"provoked? some people are just pathetic and cant handle the difficulties of life"

"now to add insult to injury the parents of the dead kids are going to pay to keep this kid alive in prison"
Could have been a lot worse, their kids could have been partially responsible for innocent people dying. Raise a bully and he might not come home from school, whether or not it's right, moral or legal it's what happens these days. It's a sad situation all around, but hopefully by keeping this kid alive they can gain some insight and help prevent future tragedies.
