I don't really like stories that go into too much personal detail (physical description is fine)... too much personality spoils it for me because my fantasies usually view women as plain objects of sexual gratification... They're there to be snuffed and butchered.... fucked and destroyed, used for target practice or for devious games.

If a character is fleshed out, has a family or exhibits too many emotions...that makes it too lifelike for me to enjoy reading about being snuffed.

This is probably because I differentiate a lot between reality and fantasy and I empathize with humans around me, and snuffing people wouldn't turn me on. I must admit I do sometimes mind-murder some hot chicks that I see on the street, but that is because I don't know ANYTHING about them so I can't fully empathize with them. Same goes for porn stars. While I do imagine some things with mental characters that are as lifelike as people, I don't usually get off to the idea of killing real people. Yeah...that about sums it up.
