Holy damn.....IDEAS!
This reminds me of my first really horrifically filthy vile character I played in FO3.
He had just finally snapped, and it was around Moira. It was at that point I realized, much to my surprise and slight repulsion, you cut cut limbs off of NPC's.
He made a mess of her, then walked out calmly.
Yes the cutting off limbs of corpses came as a surprise to me in F3.
At one point I filled the bathtub outside of Megaton with nothing more than Torso's.
The first guy I killed was the old man who sat looked after the water in Megaton, can't remember his name, I sneaked up on at night when he was sitting in his chair and stabbed him right in the skull.
I wore a baseball cap and glasses, had a beard as well. Wore pre-war clothes.
