My brother and I have the same parents, and we were disciplined exactly the same way. He has been known to steal and lie, and he loves to fight. I, on the other hand, couldn’t hurt a fly, despise fighting or arguing and find myself rather truthful for a teenager. Have you considered the thought that some violence is genetic? Parents have enough to handle as it is without trying to change the genetics of their kids. Think about your own life – do you honestly think you can blame your parents for every part of your personality?
