I don't even come close to pretending to be a psychologist, but I can't help trying to understand the situation that leads people to do horrible things. In particular, these school shootings, the last one being almost unbearable. So I would like to throw things out there and see where they go. I think the greatest clue is that he killed his mother. From his point of view (however twisted): 1) He killed his mother so she would not see what he was doing. 2) He killed his mother so that she would not have to bear the pain of what he did. Bobby Fischer once said that kids without parents become wolves. He understood this all too well, never having a father and essentially being abandoned by his mother. Luckily for him he found an art form to bury himself in. An unstable home is the harbinger of many of societal ills. The fact that he killed children is also not random: 1) He was bullied by children at this age (he was probably awkard even at this age) and had horrible memories of it. He had unresolved issues that most of us resolve and he couldn't. In a CNN interview, his mother was looking to move and "start over" 1) Theory, the school system could not handle him, made him feel horrible and isolated him even more. "Babysitting a mentally challenged child is not their problem". School systems are full of people that are overwhelmed by what should be a joy (to learn) instead is a horrible situation full of stress, memorizing things that in most cases have little meaning except to a corporation at some job. Add to that children with special needs, and it becomes unbearable for everyone. Resentment everywhere. But why this school? Whas that random?
