Do bullies bully because of their psychological problems?

Many people have endured traumatic events in their lives that could possibly cause them to bully others. Not to use this as an excuse for people to bully others, but a lot of time, there are personal reasons behind the bullying. Whether it be family problems, sexual or physical abuse, or some sort of traumatic even that occurred in their lives, there is typically more to the story. Also, when a person suffers from an inferiority complex, they tend to "step on others to make themselves higher." In this mentality, they feel better about themselves when others look worse than them.

Hope this helped!
