|Vanessa Hudgens as Cindy Paulsen in The Frozen Ground|
It's a little weird how strongly I react to images of pretty women, and from the evidence, I would say it's not just me but most men react the same way. There is one school of thought that says naked women, whether images or in person, tend to sexually arouse men. There is another that says their appearance is relaxing. I think both are true. Your reaction depends on you and the situation.
Killers, now that's another matter. Perhaps they are broken, or damaged. In any case we are lucky there aren't more of them.
