While rape and murder often go "hand in hand" in real life crimes, I've always separated them in my fantasy world of entertainment for lack of a better term.
I admittedly get off on most all 'typical' rape fantasies, but I am not into violent torture, and/or killing someone, especially a helpless victim. It completely turns me off..
If someone is killed/murdered whatever, you've taken everything from them, and 'getting off' on that is way different than just 'dominating' someone sexually, physically. I dunno, just my veiwpoint on it...
Not my thing for sure..
