I believe that some people just start out violent, and video games just feed the fire thats already there.
sure some games make you feel more powerful than you actually are, but only the psychos and idiots ever act on those feelings.
why, instead of pointing fingers, dont these so-called 'experts' work on solving the problems. people dont become violent just because the feel like it, there are always motives. no matter what a person does, the reason they do it is because they feel it is within their best interests to do so. that is the bottom line in human nature.
