@typeOU So if you were on a situation in which the end of the world had come and you have an entire group of people to protect, and so you murder people trying to steal resources, kidnap or even rape the woman and children under your protection, you would be a Psycho? How does that even work?
The nun is merely trying to protect the beastfolk children in her church from a world that clearly hates non-humans, she HAS to do this because these children are treated as if having no rights. There's nothing psychotic about wanting to protect someone.
And it's not like you didn't know this, there were quite a few foreshadowings of this in the series already. One character even asked MC about his stance towards other races, which can easily imply that the world has extremely prejudiced views about other races. To which you should've clearly related to the whole event with the nun in this chapter.
