Okay, let's put it this way.
Today's Media.. streams a lot of horrible, horrible stuff. Brutal killings, rape, murder, random imprisonment, theft, kidnapping, armed robbery and etc to name just a few. Such media is spread every day into TV news broadcasts, radio stations, and newspapers. Every single person on the planet is subject to at least two forms of this every single day, guaranteed, if there is any sort of news source around, or some kind of media. INCLUDING casual conversation.
Is everyone a rapist? No.
Is everyone a murderer? No.
Is everyone a thief? No.
If anything, playing violent video games helps to relieve stress to help relax, as well as get rid of such violent urges. Anyone who thinks that they actually make someone violent obviously has no loving clue what they're talking about.
