Video games contributing to violence among youth?

Gaming is a part of modern life whether we like it or not, most of us play video games of one sort or another but the sad truth is that approximately 50% of these games contain violent scenarios that, when practiced, reward the player. Playing such games can contribute to a whole host of problems that result in negative impacts for society 
I think violent video games should be banned.
