It doesn't make sense to me that the 'execute' action on a prisoner doesn't satisfy kill thirst/satiety.
Similiarly, organ-murdering someone necessarily involves killing them with one's bare hands. Based on the kill thirst gene's description, shouldn't that count?
Also, why does beating someone to death with a mace count for kill thirst, but clubbing them to death with an assault rifle doesn't?
This doesn't make sense, and it requires annoying micro to have a ranged pawn drop their gun before beating a prisoner to death, then pick it back up again.
