From the document (emphases ours):
"All I ever wanted was to fit in and live a happy life amongst humanity, but I was cast out and rejected, forced to endure an existence of loneliness and insignificance, all because the females of the human species were incapable of seeing the value in me."
"My orchestration of the Day of Retribution is my attempt to do everything, in my power, to destroy everything I cannot have. All of those beautiful girls I’ve desired so much in my life, but can never have because they despise and loathe me, I will destroy. All of those popular people who live hedonistic lives of pleasure, I will destroy, because they never accepted me as one of them. I will kill them all and make them suffer, just as they have made me suffer. It is only fair."
"Why do things have to be this way? I’m sure that is the question everyone will be asking after the Day of Retribution is over. They will all be asking why. Indeed, why? That is the question I’ve had for everyone throughout all my years of suffering. Why was I condemned to live a life of misery and worthlessness while other men were able to experience the pleasures of sex and love with women? Why do things have to be this way? I ask all of you. All I ever wanted was to love women, and in turn to be loved by them back. Their behavior towards me has only earned my hatred, and rightfully so! I am the true victim in all of this. I am the good guy."
"Humanity struck at me first by condemning me to experience so much suffering. I didn’t ask for this. I didn’t want this. I didn’t start this war… I wasn’t the one who struck first… But I will finish it by striking back. I will punish everyone. And it will be beautiful."
Online, Rodger left behind a number of comments on body building and pickup artist websites
expressing disgust at interracial couples and women who didn't find him attractive. He also made
a series of YouTube videos chronicling his feelings of rejection and anger.
UPDATE: Some quotes from the so-called "manifesto:"
On a trip to Morocco in 8th grade:
"In just a week into my summer break, my mother told me that father and (stepmother) Soumaya were going to Morocco, and I would be forced to go with them. This news upset me tremendously. I then asked how long this trip would be, and I was told it would be eight weeks. EIGHT WEEKS?! I could not believe what I was hearing. I threw a big tantrum.
"For one thing, I was never enthusiastic about Morocco. The country is very backwards, and that made me very uncomfortable. They didn’t even have the latest video games. And to be forced to go there for eight weeks? That would take up the entire summer and the first two weeks of high school. It was even longer than the last time we went, and I thought that was too long. I wouldn’t be able to play WoW at all for two whole months. The prospect devastated me.
"...As I expected, the journey there was a disaster. (Younger brother) Baby Jazz cried a lot during the trip, and Soumaya wasn’t at her best of moods. We didn’t take First Class, and we had to make three stops; once in Michigan, again in Paris, and yet again in Casablanca, before taking a small plane to Tangier."
On discovering masturbation:
"I started to masturbate on a regular basis. At first I only did it by rubbing my penis on my bed, but it eventually escalated to looking at pictures of girls online while rubbing my penis against my pants, fantasizing about doing sexual things with them. I didn’t know how to access any porn sites, so I would just browse regular websites until I found a picture of a hot girl to masturbate to.
"I developed a very high sex drive, and it would always remain like this. This was the start of hell for me. Going through puberty utterly doomed my existence. It condemned me to live a life of suffering and unfulfilled desires. Even at that young age, I felt depressed because I wanted sex, yet I felt unworthy of it. I didn’t think I was ever going to experience sex in reality, and I was right. I never did. I was finally interested in girls, but there was no way I could ever get them. And so my starvation began."
On being bullied in 10th grade:
"I was completely and utterly alone. No one knew me or extended a hand to help me. I was an innocent, scared little boy trapped in a jungle full of malicious predators, and I was shown no mercy.
"Some boys randomly pushed me against the lockers as they walked past me in the hall. One boy who was tall and had blonde hair called me a "loser", right in front of his girlfriends. Yes, he had girls with him. Pretty girls. And they didn’t seem to mind that he was such an evil bastard. In fact, I bet they liked him for it. This is how girls are, and I was starting to realize it. This was what truly opened my eyes to how brutal the world is. The most meanest and depraved of men come out on top, and women flock to these men. Their evil acts are rewarded by women; while the good, decent men are laughed at. It is sick, twisted, and wrong in every way. I hated the girls even more than the bullies because of this."
On seeing a family friend kiss a girl:
"In the Spring, something horrible happened that will haunt me forever. We met up with the Bubenheims at the Sagebrush Cantina in Calabasas, and a friend of Pollina’s was there with them, named Nicole, a girl around my age. She sat next to Leo the whole time, and by the end of the dinner, the two of them were making out. Twelve-year-old Leo was making out with a girl who was almost my age. Not only does Leo have a better social life, but now he was making out with girls, AT AGE TWELVE!
"They made out for a long time, and I could see them tongue kiss. They knew I was watching with envy, and they still did it. I bet that lucky bastard took great satisfaction from my envy. There I was, watching a boy four years younger than me experience everything I’ve longed for… to kiss a girl… to be worthy of a girl’s attraction."
On deciding, at age 17, to get revenge on people who had sex:
"One day I found some posts on the internet about teenagers having sex, and I was once again reminded of the life I had been denied. I felt that no girl would ever want to have sex with me… And I developed extreme feelings of envy, hatred, and anger towards anyone who has a sex life. I saw them as the enemy. I felt condemned to live a life of lonely celibacy while other boys were allowed to experience the pleasures of sex, all because girls didn’t want me. I felt inferior and undesirable. This time, however, I couldn’t just stand by and accept such an injustice anymore. I refused to continue hiding away from the world and forgetting about all the insults it dealt to me.
"I began to have fantasies of becoming very powerful and stopping everyone from having sex. I wanted to take their sex away from them, just like they took it away from me. I saw sex as an evil and barbaric act, all because I was unable to have it. This was the major turning point. My anger made me stronger inside. This was when I formed my ideas that sex should be outlawed. It is the only way to make the world a fair and just place. If I can’t have it, I will destroy it. That’s the conclusion I came to, right then and there."
He continued this theme later on, at age 18:
"I delved more into learning as much as I could from books at Barnes & Noble. I expanded on the political and philosophical ideals I concocted when I was seventeen, and I soon became even more radical about them than I ever was before. It was all fueled by my wish to punish everyone who is sexually active, because I concluded that it wasn’t fair that other people were able to experience sex while I have been denied it all my life. I started to have the desire to create a world where no one is allowed to have sex or relationships. I again saw that as the perfect, fair world. Reproduction can be accomplished without sex, through artificial insemination. Sex is evil, as it gives too much pleasure to those who don't deserve it."
On getting kicked out of his father's house at 18 by his stepmother:
"Not only did she kick me out of father’s house, but she forbade me to go there even for a short visit. And still, father didn’t do anything about it. Father kept saying that the house is her house as much as his, and that she has the right to kick me out. No! I am the eldest son! The house should be MY house before hers! This caused any respect I still had for my father to fade away completely. It was such a betrayal, to put his second wife before his eldest son. What kind of father would do that? The bitch must be really good to him in bed, I figured. What a weak man."
On refusing to get a job after dropping out of community college:
"I refused all of the jobs that (life coach) Tony suggested to me. The problem was that most of the jobs that were available to me at the time were jobs I considered to be beneath me. My mother wanted me to get a simple retail job, and the thought of myself doing that was mortifying. It would be completely against my character. I am an intellectual who is destined for greatness. I would never perform a low-class service job."
On finding out his mother was dating a wealthy Hollywood executive:
"When I found out about this, I started to harbor the hope that my mother will get married to this man, and I will be part of a rich family. That will definitely be a way out of my miserable and insignificant life. Money would solve everything. I started to frequently ask my mother to seek marriage with this man, or any wealthy man for that matter. She always adamantly refused, and demanded that I stopped talking about it. She told me that she never wanted to get married again after her experience with my father. I told her that she should sacrifice her well-being for the sake of my happiness, but this only offended her further."
On enrolling at another community college:
"A new college provided a new start, and this college looked perfect in every way. I had the hope that I could make it there; that I could make friends, meet some girls, and eventually find a pretty girl to be my girlfriend. I pictured her in my mind all the time; her cascading blonde hair, her beautiful face, her sensual body... Everything. I imagined us walking hand in hand through the college, looking at the magnificent view of the mountains in the distance as the sun sets behind them. That would be heaven. That was what I wanted in life."
On seeing a happy couple at a Christmas party:
"During the remaining days of 2010, I joined my mother and sister at (mom's boyfriend) Jack’s beach house in Malibu to spend a few nights. They arrived there a few hours before me, and by the time I reached the house they had already invited a few guests for an afternoon get-together. To my outrage, I saw that mother had invited (family friend) Maddy and her boyfriend. I was looking forward to having another respite at the beautiful Malibu mansion where I can indulge myself in opulence and forget about my depressing loneliness. Having a young couple lurking around only reminded me of my insignificance. I was extremely upset with my mother for inviting them. She should have been more considerate."
On reflecting on his life, at age 19, before tranfering to college in Santa Barbara:
"All while I was suffering this lonely existence, other boys my age lived their happy lives of pleasure and sex. I can never forgive such an injustice, and it was my bid to overcompensate for it in the future. I had to make up for all the years I lost in loneliness and isolation, through no fault of my own! It was society’s fault for rejecting me. It was women’s fault for refusing to have sex with me."
On his first week in Santa Barbara:
"My two housemates were nice, but they kept inviting over this friend of theirs named Chance. He was black boy who came over all the time, and I hated his ******re attitude. Inevitably, a vile incident occurred between me and him. I was eating a meal in the kitchen when he came over and started bragging to my housemates about his success with girls. I couldn’t stand it, so I proceeded to ask them all if they were virgins. They all looked at me weirdly and said that they had lost their virginity long ago. I felt so inferior, as it reminded me of how much I have missed out in life. And then this black boy named Chance said that he lost his virginity when he was only thirteen! In addition, he said that the girl he lost his virginity to was a blonde white girl! I was so enraged that I almost splashed him with my orange juice. I indignantly told him that I did not believe him, and then I went to my room to cry. I cried and cried and cried, and then I called my mother and cried to her on the phone.
"How could an inferior, ugly black boy be able to get a white girl and not me? I am beautiful, and I am half white myself. I am descended from British aristocracy. He is descended from slaves. I deserve it more. I tried not to believe his foul words, but they were already said, and it was hard to erase from my mind. If this is actually true, if this ugly black filth was able to have sex with a blonde white girl at the age of thirteen while I’ve had to suffer virginity all my life, then this just proves how ridiculous the female gender is. They would give themselves to this filthy scum, but they reject ME? The injustice!"
On women:
"Females truly have something mentally wrong with them. Their minds are flawed, and at this point in my life I was beginning to see it. The more I explored my college town of Isla Vista, the more ridiculousness I witnessed. All of the hot, beautiful girls walked around with obnoxious, tough jock-type men who partied all the time and acted crazy. They should be going for intelligent gentlemen such as myself. Women are sexually attracted to the wrong type of man. This is a major flaw in the very foundation of humanity. It is completely and utterly wrong, in every sense of the word."
On getting lunch with his dad in Santa Barbara:
"When we sat down at our table, I saw a young couple sitting a few tables down the row. The sight of them enraged me to no end, especially because it was a dark-skinned Mexican guy dating a hot blonde white girl. I regarded it as a great insult to my dignity. How could an inferior Mexican guy be able to date a white blonde girl, while I was still suffering as a lonely virgin? I was ashamed to be in such an inferior position in front my father. When I saw the two of them kissing, I could barely contain my rage. I stood up in anger, and I was about to walk up to them and pour my glass of soda all over their heads. I probably would have, if father wasn’t there. I was seething with envious rage, and my father was there to watch it all. It was so humiliating. I wasn’t the son I wanted to present to my father. I should be the one with the hot blonde girl, making my father proud. Instead, my father had to watch me suffer in a pathetic position. Life is so cruel to me."
On realizing how he'd get revenge on everyone:
I ordered my coffee and sat down on one of their chairs to relax. A few moments later, when I looked up from my drink, I saw a young couple standing in line. The two of them were kissing passionately. The boy looked like an obnoxious punk; he was tall and wore baggy pants. The girl was a pretty blonde! They looked like they were in the throes of passionate sexual attraction to each other, rubbing their bodies together and tongue kissing in front of everyone. I was absolutely livid with envious hatred. When they left the store I followed them to their car and splashed my coffee all over them. The boy yelled at me and I quickly ran away in fear. I was panicking as I got into my car and drove off, shaking with rage-fueled excitement. I drove all the way to the Vons at the Fairview Plaza and spent three hours in my car trying to contain my tumultuous emotions. I had never struck back at my enemies before, and I felt a small sense of spiteful gratification for doing so. I hated them so much. Even though I splashed them with my coffee, he was still the winner. He was going home to have passionate heavenly sex with his beautiful girlfriend, and I was going home to my lonely room to sleep alone in my lonely bed. I had never felt so miserable and mistreated in my life. I cursed the world for condemning me to such suffering.
"I wanted to do horrible things to that couple. I wanted to inflict pain on all young couples. It was around this point in my life that I realized I was capable of doing such things. I would happily do such things. I was capable of killing them, and I wanted to. I wanted to kill them slowly, to strip the skins off their flesh. They deserve it. The males deserve it for taking the females away from me, and the females deserve it for choosing those males instead of me."
...
"Every time I looked out my window to the courtyard, I saw young people socializing. Obnoxious drunk boys were chatting up pretty girls, and I wondered with great panic if they would be having sex together in the night. I often fantasized about barging into their rooms while they had sex and slashing them to death with my knife."
Reflecting on life on his 20th birthday:
"My teenage years were completely denied to me by the cruelness of women. The only way I could make up for it was if I could have an extraordinary sex life in my twenties. I would have to have a profoundly amazing decade in my twenties to compensate for all the misery I experienced in my teens. If I fail to do that, then I have nothing to live for. Sadly, I will only experience the opposite in my early twenties, and it will destroy me."
On making up with an old friend:
"Addison had changed and matured tremendously, and he was no longer associating with the popular Malibu high school kids. This didn’t change my resentment towards him, and I kept confronting him the whole time about the insulting way he treated me over a year ago. After a lot of debating, we agreed to resolve our conflict with each other. This didn’t mean I forgot all of the slights he dealt to me in the past, however. I never forget. I never forgive. One day I’ll show him how superior I am."
On meeting some new housemates:
"Their names were Ryan and Angel, and to my dismay they were of Hispanic race. In addition, the two of them were already friends with each other, which meant that they could possibly gang up against me if any conflicts were to arise. They also seemed like rowdy, low-class types. My first impression of them soured me, but I tried to be pleasant and not show it. The two of them acted cordial to me on the first day, but after observing them for a bit, I had a bad feeling that they would be trouble to live with... And they were to be my housemates for a whole year! When I was alone in my room, I panicked to myself at how dire a situation this was. This was extremely disappointing. I was hoping I would get decent, mature, clean-cut housemates. Instead I got low-class scum.
...
"On the day after, I almost got into a physical fight with Angel. The ugly pig kept acting as if girlsthought he was more attractive than me. Hah! I am a beautiful, magnificent gentleman and he is a low-class, pig-faced thug. I had enough of his ******re attitude, and I started to call him exactly what he was.I tried to insult him as much as I could, telling him how superior I am to him, and saying that he was low-class. He tried to attack me, but Ryan, being the more mellow of the two, held him back. A pity, I was itching for a chance to hurt that obnoxious little animal. Though I suppose it was for the best… My life was too important to risk doing anything rash."
near the University of California, Santa Barbara campus in the Isla Vista neighbourhood. The identities of the victims were not immediately released.
wow that's something.
He sounds like a self-entitled little bastard, and I doubt much of anything would have changed his opinion of humanity.
