I kind of have two, both in the similar vein, both probably disgust most people (even on here..)
The first being, stalking someone long enough to know their mannerisms and more importantly, their fears, then abducting, torturing/violating them to the point of death.

The other being essentially the same, only having my girlfriend help me with it. She can be a vicious little bitch, and it's almost never that I actually get to watch her hurt someone, which is a shame.
