yes time to kill every demon in town and then pull a batman and take the heat coz fuck it
this is fantasy, the demons look like humans and talk like them, but their core instincts are to bullshit everyone, just because something talks doesnt mean there can be dialogue, also for the ppl getting mad at this...
we have had good demons or neutral demons like in 95% of mangas, hell it has gotten to the point that a bunch of times the angels are the super assholes while the demons are good and mistreated, so im so fucking happy with these pure fuckery demons.
the only problem ppl have is that since they look human they think its a 1:1 representation of our world, and that this manga now promotes bigotery to other races and thats is BULLSHIT
This is a fictional world, maybe there's a bunny looking monster that eats ppl or some shit, just because it looks like a fucking bunny doesnt mean its a bunny!
And yes! they may be a good or neutral demon, but it will take a long ass time for a demon to fully learn and maybe understand feelings and these demons are at the barrier city and they are in the middle of a kinda war atm, they cant go ''ehh maybe they aint so bad'' atm, coz if they fuck up then the whole city goes to shit and from there its a whole ass domino effect.
man i suck at explaining my point, but basically dont try to correlate everything to real life, sometimes human shaped monsters are just human shaped monsters
