I think we all like to believe the best in people, but sometimes, it's unfortunately necessary to let go of the idea that certain people are ever going to feel remorse for what they have done.
It is NOT a normal person who inflicts such suffering and pain on another living thing.
Interestingly enough, I just got a copy of Oprah magazine, in which there's an interview w/the woman behind the new US hit series 'Medium'. This woman is well known and works w/police and the FBI in a medium capacity. She does at time try to sense things from the mind of the perpetrator, and she brought up that some criminals do pass and they do NOT feel remorse for what they have done.
I honestly believe some people deserve to be locked up without the possibility for parole. EVER.
It does work. There are no riots about it.
