Shoot, all the horror movies I've seen, the pretty/ sexy girl is the FIRST to die. Usually right after she sleeps with someone... then wanders off in just some skimpy panties/lingerie to get killed.
When it comes to physical violence or means of killing, usually it's going to be men. Statistically, men are more likely to be serial killers, especially using violent means (Ted Bundy, etc.) Also, men are generally physically stronger-- they are far more likely to be able to over power another person than the average woman could. So, it's more believable in that regard to have evil bad guy men.
As for "most" I think you'll find that there is no "most" in fiction. There may be many, but there are so many variations, so many stories told, that there is never a most. =)
