I was raised with video games, I'm a gamer from the age of 7, used to play Pong on the "original console" and lot's of games on Amiga ZX spectrum, and played lot's of games since 286 pc's era, violent or non violent.
I've never had any violence issues (except for minor fights as kid, that are inevitable), and guess why? because of my education. My father told me to never hit a girl in my life because the day I do that I won't be a man anymore and I never did it even when I was a child playing with children, my father told me not to mess up with the wrong people and never do what they do, and I listened, because I had great respect for him all my life ...
So, its' not the games, it's the education, a good childhood and nice parents that determine how you act on violence, not the games ...
