Oh, no, I'm thinking if she goes bot like, to determine kill objective, she probably quantify evil & use that as kill order. Within eyesight, there is big baddie (demon) & small baddie (ares), in an enclosed environment(dungeon) where damage will not spread (collateral damage is constant, that small party only), her first objective would be the demon, no? I'm not saying Ares will not get target, I'm just saying there are no reason for her to not target the demon first, personality or not. This is no demon king in far off place that she might have to calculate in distance vs 'evil efficiency', the demon, ares and the party are all in eyesight.
