Are guys more attracted to violence or ?

Well, me and some guys was taking about this one... Book. Lot of zombies and alot of naked chicks. Thing is, I forgot about the naked girls when I noticed one of the main characters just gotten himself eaten, and a one of my friends noticed that too (There was four of us, btw). The other two thought I was weird that I was looking at all the gory stuff and not the scenes. I'm not a scientist or anything, so i won't make a study of this, but I just want to know what you guys think about it.
