based on me, no.
ive spent my whole life playing violent video games, played all the GTA games as a kid, all the CoD games, doom, UT as a kid, im the most unviolent person ever. how ever it did mess up my social life. i always laugh when news tries to blame someones behavior on video games.
although i understand things affect people in different ways, some people might get really affected by it, but as a child its really up to the parent to monitor what games the child is playing, and if they are having any effect on them, to take action.
