The resurrection of NPCs would tie in here pretty neatly imo.
I was really bummed when i couldn't revive Paladin Cork, as it is really nigh impossible to keep him alive through the suicidal episode that he calls combat.
Naturally, there should no longer be an EXP gain from revived NPCs, but if they weren't hostile prior to being revived, they should atleast come back neutral (or just make it impossible to revive enemies to begin with).
In the case of friendlies/neutrals turning hostile in combat the resurrection could pick up the disposition before combat and maybe remove a bit of goodwill? I'm not too sure about the correct implementation of such a mechanic, but a forum is just the place to throw something like that out there and hope for the best.
