I admit that I don't mind a little violence now and again, myself.
I'm a huge fan of horror films... even some that are almost going over the edge. That's mainly because I am into special effects makeup, and I love to watch a gore movie and try and see how they accomplished it. From a makeup artist's view point. ^.^
Death used to be very entertaining. Ask the Romans. They couldn't get enough of it. It's the same thing today... Only it's horror/action movies, and things of that nature. Even boxing. It's a violent sport, let's face it. Rewind history to the days of the Roman Empire... Take those boxers and stick them in the Colosseum. Our sport is a mild version of what the Romans craved.
We have a fascination with the taboo - And in most cultures, death is very taboo. And there is a morbid fascination on some level with death and violence. In a way, it reminds us we are still human and very mortal.
