Do Games Help Cause Violence?

Recently there has been a lot of talk about games causing violence. There is a valid point to what people are saying about murder in a virtual space maybe, possibly having something to do with tragedies that happen in the real world. While the idea of video games training you to kill is absured, the idea of it implanting a sort of bloodlust into our minds, and personalities, is not. However, the truth of the fact is, if you are ready to kill, or cannot tell where virtual reality begin and ends, it should not be noted as the games fault. It is the person who commits fault, and if games caused this, it can be assumed that the person in question had something wrong with them beforehand. If the person just so happened to be playing a game as a hobby, it would be comparable to blaming someones breakfast cereal.
