I dont know him, but I dont think that Joe is actually going to go out and shoot anyone. I can understand, if he suffered from bullying like that, his attitude towards bullies.
I dont think its just insults that kids go through, I know of a couple of kids in high school who were subject to on a daily basis, not just name calling, but humiliation that was just so sick and horrible I dont know how the kids who were doing it lived with themselves.
I dont think that anyone should be killed, other than in self defence, if your life is in danger, or in the case of the death penalty, those are the only 2 reasons.
I DO think that kids who do that kind of bullying, need to be charged with a crime, and pay for what they have done mentally and physically to innocent young people. Perhaps being in prison, and seeing the other side of what they do might change them.
