As much as I wanted a "flawed hero" scenario, I feel like this works out almost just as well. Like it would be cool to see a story where maybe the protagonists were wrong in their judgement, but in this case, it would completely undermine everything we've known up to this point about the Hero, his companions, and their journey.
Maybe I'm reading into this too much but this is sort of a 'return to form' in that demons are just that, DEMONS. They aren't another race we can communicate with, instead, they are our mortal enemies. Why? Who knows for other stories, but in this one, it's clearly defined and shown. They are the predator to humanity... and so for us to live, they must die.
But damn. That line about using "mother" is convenient was just... DAMN... Fucking. Ruthless. And I loved it.
Edit: Scratch that part about reading into this too much. ALL Y'ALL ARE THE SAME! ... AND I LOVE IT! 🤣
Edit2: Wow. Okay. I was not expecting this when I just wanted to post a random comment on my thoughts about this glorious chapter and then jump ship to catch up on other manga. There is a LOT to digest with this whole thread. But my main thing is that people are taking these... how should I put this... ideologies a bit, no, WAY too far. I personally don't see this as analogous to human A vs human B. I definitely see this as sheep accepting a wolf (that they've seen on numerous occasions tear their friends and family limb from limb, devour their flesh and organs down to the bones, and then piss on their skeletons just because they can, aka to show dominance) into the herd just because the wolf went "baaaaah baaaaaaaaah" a couple, a few times. This isn't an ethnicity or race difference, no no no, THIS IS A DIFFERENCE OF SPECIES. Actually, no, taxonomically speaking, this is a difference of ORDER, maybe even CLASS.
I understand where some people are coming from, I really, truly do, but this manga, more specifically, THIS CHAPTER, is not the place to be having this discussion. The demons themselves even say it, THEY. ARE. MAN EATERS. There is no argument, or at least, there SHOULD be no argument over this FACT (in this world, anyway). This chapter LITERALLY gave us an example of what would happen to humans with the ideology of 'demons can be redeemed' or whatever in the village chief. Demons don't understand the human language. They may be able to imitate it, BUT IT'S FOR THE SOLE PURPOSE OF DECEIT. I don't have a good way to end this so...
