More like if you had the chance to kill the person telling you to do it, would you kill them or not.
Kumoko hasn't encountered a single friendly creature for a long time. Even her siblings were cannibals and her mother tried to kill her. The only not hostile things were the corruption larvae. No human has been friendly, which isn't surprising since it's basic logic humans enter the dungeon to hunt monsters. Such circumstances will start to shape your mind. She's not anymore the same person she used to be, ignoring the body/species difference. The other reincarnators we have seen so far are humans or elves with jolly circumstances, all the way up to a royal prince. The dragon one is a prince's pet, no less, living a similarly leisurely life. They have the luxury to uphold high morals, but even so one got rotten.
Ainz and his cohorts are evil, Kumoko is merely neutral by now, like a wild beast. A lion might kill and eat humans, but it's not evil. If Kumoko gets out of the dungeon and starts massacring civilians in towns, then we can call her evil. If she eats the human bodies, she will have abandoned a big portion of her former humanity, but that's all.Originally Posted by MFauli
