Violence on TV

Today, violence is a prevolent genre in media. You see it everywhere in movies, tv shows, and even games. If it does not have violence is it cool? Probably not. But do I think that its bad? No, Violence has been present in the human race ever since society was a thing, I do not believe it has a direct effect on the behavior of humans, they see things that are worse.  An example of a violent tv show that I can think of that I watch is Dexter, its a show about this man who is a serial killer because he physcologiclly needs to do it, but he only kills very bad criminals and is a good person at heart.
