When something like this happens I always wonder why.
This didn't use to happen, did it? What changed? I think of all the usual 'suspects'. Violent video games. Over prescribed childhood ADHD drugs. Absentee parents. Are any of those things the culprit? What has created this rare but deadly new type of human being who glories in rampages?
I remember in a few angst filled moments in high school thinking, "If I died everyone would be sorry." It was never serious but that sort of thought floats through a kids head sometimes.
The NEXT thought that always came to me was a notion I'd picked up somewhere that if I killed myself I'd go to hell. I think we've lost our religious. There have always been unbelievers but not like now.
