> Humans aren't adapted to the possibility of reconciliation, our knee-jerk reaction is revenge out of past necessities. But if we can afford to rehabilitate someone, we absolutely should. We should never limit the rights we grant people purely out of vengeance.

I don't think punishment for criminal action is "revenge" or "vengeance". In theory, it is suppose to stop the possibility of it occurring again and hopefully deter people attempting it.

My opinion is that society needs to be protected from certain people.

If you tell me with a straight face that if someone mutilated your kids and did unimaginable things and you are truly fine with accepting that he will live his life as if nothing happened after a few years, I wouldn't believe you are human.

I can be downvoted to oblivion, but it won't change certain facts and realities.
