Children and Violence

Is the world getting more violent or less violent? In my opinion, violent cases are increasing in the world. It is because I often hear the news about child abuse, terrorism, violent crime of children and so on. I am especially interested in the last one, violent crime of children. The reason is that I have never come up with using violence when I was in trouble. I want to know why children tend to become violent. Is there anything that we can do for them? Let me think about it through this opportunity.
