No, I don't think a game or any inanimate object can "cause" violence. That is something only a person can do.
However, if a person spends their whole life playing violent games, and they don't interact with society, it may alter their grasp of reality. They may devalue life or think that violence is acceptable, but that in itself doesn't cause violence.
I really don't know, I am an economist, not a psychotherapist.
