Bullying is taught at home, imo. These kids learn intolerance from their parents, then act it out at school.
I concur with what you say, Talesin. Yes, I think that's true in far too many cases. But I also think that in a lot of cases the bully has learned his trade from others at school. In the case where the bully has learned intolerance at home, the parents are even more blameworthy than the bully. But do we see the mother of this particular bully accepting any responsibility for what her son had done? What we see, instead, is her having said: "My son has suffered, too. His face is permanently scarred and the injury from the pencil required nine stitches."
Wouldn't it have been nice to have heard her say something like: "My son's own actions is what caused him to be injured. He should be ashamed of himself!"
