Causes of Bullying

"Psychologists used to believe that bullies have low self-esteem, and put down other people to feel better about themselves. While many bullies are themselves bullied at home or at school, new research shows that most bullies actually have excellent self-esteem. Bullies usually have a sense of entitlement and superiority over others, and lack compassion, impulse control and social skills. They enjoy being cruel to others and sometimes use bullying as an anger management tool, the way a normally angry person would punch a pillow." -Jane St. Clair

This is a part of an article written about the reasons people bully, primarily in teenagers. The article comes from a site made by parents for parents. It's used as a resource for parents of teens.

I also found another article on the MassGeneral Hospital for Children that talks about "causes, consequences, and practical advice."
