I don't condone what those teens did, but I do get it, to a point. They were teased and harassed, and for some teens, they can't handle that. It just becomes anger and hatred, and for some people, it eventually explodes.

I think those who are predisposed to it might be influenced by violent video games. Not everyone is. And just because you're exposed to something, doesn't mean it will make you become like it. Just because you're desensitized to something, doesn't mean you don't care. Doctors have to become desensitized to blood, screams of pain, dead bodies, and odors of sickness. But that doesn't mean they don't care.

I watched horror since I was a kid. I don't freak out because I see gore in a movie. But in real life, it's a whole other thing. Not everyone responds the same to what they see.
