Guys, I need help!
So I have a friend who was a great friend a year ago, you could talk with him about cars, weapons, girls, etc., and now he's totally lost his mind. He watches those life-sucking animes* all day, and he now hates us (Me and my 2 other friends), because we said he should not watch that much of it.
He said we are schumbags because we believe in God, he wants us to believe that Lucifer from the anime is the only true God. He says that when he will die he'll become a demon with red eyes, wings, 2x power, and he'll be the servant of Lucifer, and he'll kill us. He always talks about Tokyo Ghoul, and he says he's starting to feel hungry whenever he sees blood, or chopped arms whenever he watches that. And he keeps showing us those toxic things on 9gag, and those fat nude anime girls, he always says: "THICC!" But we actually don't care about those, we told him, and he got upset again.
He always starts a war against us and against the teacher when we are in the school, he says that there is no heaven, only hell, which is much cooler (In my opinion maybe there is both heaven and hell, or both is just fantasy, since I'm not really a religious person).
My other friend said, those animes are just drawings, and aren't real, he (the former good friend) started to punch him.
What should we do? Should we leave him alone or do something about this problem?
