Was stealthing around in a mage dungeon just now, and was coming up to where I knew a spellsword was lurking. Got careless, and she caught a glimpse of me- I snuck away quick and avoided a fight, but during the short time while she was in caution/alert mode, she did what she was programmed to do in defense- resurrect a nearby dead thing to assist her. I knew there were no human corpses near there at all, so didn't know what it was that she'd rez'ed. I just waited until the red dots disappeared from the compass, and snuck back in and backstabbed her to death. While looting the area, I found the ash pile from her resurrection spell, so I looted it- a chicken briast. She had resurrected a chicken to assist her, from a nearby plate of food.
These NPC's scare me, sometimes.
