Since I'm the resident almost-liberal, I guess I'll weigh in. I do tend to feel sympathy for all parties involved when I read such things. I wonder how that bad guy got to be a bad guy, and figure in most cases it was just a series of bad choices and bad circumstances. I feel a lot of sympathy for someone who is so desperate that they end up threatening or killing someone. But parenting has a lot to do with it, as well. I know my mother would have whooped my butt for major infractions of my childhood. That, and the fear of disappointing her kept me in line.
Then again, there are also some bad seeds out there. There are just some people who have no sense of empathy or social norms. Sociopaths are likely born that way, and no amount of parenting can set them straight.
We've all made mistakes. I'd wager that half of us on this forum are walking around free when we ought to have been charged or imprisoned for some infraction, however small.
But we all make choices in life, and when you do wrong you risk getting caught, and when you get caught you have to face the consequences.
