What makes a child become a bully? It's a question researchers have been diligently trying to answer for years. Are bullies born with a bullying gene? Do children learn to be bullies through their environment and social conditioning? Is a certain type of parenting to blame? Is exposure to violent television or video games the problem? The answers to these questions aren't always clear. But it is known that bullying behavior often has its origin in early childhood, and that a variety of environmental and social factors combine to create a child capable of bullying.
