I've ranted about this before, but rights applied to prisoners are joke. When the financially struggling, but law abiding people have less access to medical, education, entertainment, etc., than criminals who are in prison for violating others' rights, it is in need of an adjustment.
I don't believe in death penalty either. In case of repeat offenders of crimes like rape, I think the death penalty is warranted. But even then, they need to do it cheaper. Lethal injection? Too costly. Adequate caliber bullet or two to the head will do the job, and maybe you should be required to dig your own hole.
If I had the say in sentencing, if you are clearly guilty, and if the offense is serious enough, I'd put you in a labor camp. Eternal sleep is too easy. I'd put you to work for rest of your life, paying back to the victims and the society you've violated. No TV, no internet, minimum comfort, minimum free time.
They'd be begging for second chance, and IMO, that's how prison should be. No more room in your local prison? That's because they are doing it wrong.
