Does video games cause violence

well i played lots of violent games and i do not think that i will ever try do those violent things in real life. I played lots of games. I played games hours & hours but feel that i should ever those things in real life. I use games to fulfill the desires that i can not accomplish in real life. So if you can not fight like a hero in your real life just do that in games. Real life these things are really difficult but in games they are just matter of practice.
