A lot, perhaps even the majority of school shooters have been social outcasts and bully victims. If they weren't bullied past the line perhaps they would never have cracked. I'm not defending school shooters, what they do is horrific. But I don't believe every school shooter is truly a monster. The reason bullying isn't tackled is because of 'political correctness.' Nowadays, bully victims are blamed and bullies are glorified. A while ago I was the one who was moved into a different class and not the person trying to bully me. Plus the fact that school expulsions are extremely rare nowadays, recently a guy only just got expelled after having assaulted a total of 3 people in a few months. Basically nowadays bullies are regarded as lovely people and bully victims are the bad guys.
