Lwk, the whole “humans are destroying the planet, so their population needs to be controlled” thing isn’t even a particularly unreasonable position for another sentient species to have. Forgive my baby’s first foray into ethics of war, but I feel like military intervention would even be just, as humans are a genuine existential threat.
Though, because this is a tit and ass comic, I think the author will just default to hitlerite characterization to make it clear that the demons are the bad guys.
