I was making a general statement about when anime has a political theme, not on that particular anime.
Only anime I know of where this is actually a thing is Attack on Titan, but I haven't watched the last season (apparently it deviates from the source material, maybe for this reason, which is why I haven't).
Though I guess you could find a utopian vision in a nation that views all to be equally worthless and champions genocide and calling the dark young of shub niggurath to stomp on people.
Yeah, I do like multifaceted morally grey and villainous characters with interesting or even aspiring motives. I highly recommend Hunter X Hunter, The number of characters in that anime that aren't majorly flawed in one way or another you can count on your fingers. One of the communities favorite characters is a murderous pedo clown that serves as the main characters mentor and drop-in father-figure for a large part of the story. If you watch any single anime and never watch anime again, let it be HxH.
