In my opinion, No. Usually the only people who become violent or inspired to commit violence from video games, are people who are either violent to begin with or have deep rooted physcological problems. Though it should be noted that if a child is raised in a violent enviroment or one in which they are allowed to have violent outbursts without any sort of control or punishment, then they could possibly be influenced by videogames. Most children with anger problems that I have encountered, are the same children who sit around and play M rated games (Which their parents buy on a whim for their children) all day and then throw a tantrum when something doesn't go their way. In essence, it's just deep rooted to bad parenting choices of allowing children access to Adult games without any sort of restrictions or monitoring, or emotional/mental issues.
