Oh, look. I invade a peaceful trading hub. Of course people die, but *teehee* at least I told them to not kill too many. Also, even though I started a sneakattack from the inside on you guys, I won't enslave or kill you (any further), but just take away your freedom to govern yourself. Ain't I dashing?
... I don't know, but even though I see stuff like that happening all the time in such a setting, I can't really sympathise with the MC. He is the villain so far, no matter how you look at it. The author better come up with a good bg-story, how the alliance is trying to genocide the demon races, because it confuses them with monsters (, which might be a bad thing. I don't know, but it seemed to matter to MC).
