Not every kid that's plays violent games will become violent but there are some that will and those kids are probably prone to anger and would have come across it later in life. Also I agree with other comments its not illegal for young youth to play Teen and Mature games. All that says is maybe they have some poor parenting going on in there lives. I believe the problem a lot of the time in those situations don't inform them self's enough they just don't care so they just buy any game their kid wants. If parents knew more they might be more inclined to tell their kids no they play games like that when there older.
