The biblical advice to "judge not, that ye be not judged" seems relevant here. It's pretty obvious to me that it refers to a person's heart, that is, their internal desires and motivations that no one but them can truly know. If that motivation leads to a person acting the way I'd like them to, and they claim it's for reasons I agree with, and I'm not on the parole board or one of their family members where I have a need to look deeper, then fine.
You really need to come up with actual evidence for that if you keep repeating it everywhere.
I wholly believe psychopaths can be redeemed and live a fulfilling life without hurting anyone if given the proper support and guidance. I don't for a second believe the US legal system is equipped to do that, especially the prison system.
