I'm glad my group of friends never bullied anyone. If I were in the shoes of someone being bullied, I don't think I could stop myself from doing something drastic to stop it. Columbine is a bit extreme, but you can't get away in life walking over people. It doesn't end in highschool either, so you gotta learn to stand up for yourself eventually. These kids probably didn't want to hurt another person so they took it out on themselves.
