A few things:
I partly blame the parents. If parents had taught this kid to fight back and not take shit from people, he could have done something to make a point. I'm not an advocate of violence, but hey, at what point is enough, enough? Sometimes you have go to drastic measures, especially if people are bringing harm to you.
Next, why is this kid on a Social Networking site if that is where his bullying was taking place? Hello?? Disable your account and leave the site.
Lastly, sure it's sad that he took his own life, but that's pathetic and I have no respect for that. Life gets rough sometimes, that's the way it is. Anyone can take their own life. It's harder to deal with and work through your problems and that's why people cop out and do things like this. If I go home and jump out of my apartment window right now, that's it for me. However, no one should be thinking "Oh wow, things must have been so rough... blah blah blah." They should be thinking "Damn, I always thought he was better than that..."
