I think people that kill/rape children should not be put in jail, nor should they be put to death. Someone who wants to do that stuff is obviously fucked in the first place, and acting on there instincts just as we would a member of the opposite sex. I never understood why throwing someone in jail or killing someone was better than rehabilitation.
I really can't get behind this. I mean, I'd say that most people who kill another human being period without a strong motive are kind of fucked in the head. So, we'd make a distinction for people who killed/raped
children, because it's a much more disgusting thing and therefore the person must be fucked in the head?
The Justice system is really also for people who are "fucked in the first place." It's not about making people pay for doing horrible things to each other as much it is trying to keep people from doing more horrible things to each other in it's own semi-dysfunctional way. So, even if a person is mentally unstable, in my opinion, you can't really make that distinction and not at least lock them away for the horrible thing that they did just under the assumption that they are too "fucked" to be dealt with in a way that would make everyone safer.
Given, I really only have a real issue with the fact that you mentioned "jail." Hell, I'm not saying that we should kill kill kill with an objective look into what the person did and disregard the mental state of said person, but in case you didn't know rehab isn't often a very effective system and sometimes, even if the person has mental problems to blame for it, they really need to be in jail, not for the purposes of retribution but for the purposes of keeping people safe.
