"The connection between bullying and violence toward others is more complicated, although again there's a correlation. Bullied kids often become bullies themselves, which appears to be what happened with Dylan and Eric. Larkin cites a student who claims they terrorized her brother, a student with special needs, so badly he was afraid to come to school. Researchers call students who both bully and suffer bullying "bully-victims," and find that these bully-victims are at the greatest psychological risk. "Their numbers, compared to those never involved in bullying, tell the story: 14 times the risk of panic disorder, 5 times the risk of depressive disorders, and 10 times the risk of suicidal thoughts and behavior."
