I guess that's one way to put it bullys can be seen as a lost cause, unworthy of teaching or you know the dangers of hurting others so you have the chance to be better than them. So in a way they're using the bullies to make you stronger, But it's not the other student's job to make you stronger it's just the teachers The bullies are at school to learn too The teacher should just teach them not to be bullies and build up the good students instead of teaching them trial by fire.
