yeah, feels like a wasted potential where we could have a morally grey antagonist, instead its just selfish villainess who do more collateral damage to achieve her ideals
considering the MC, im sure the end will be usual: villainess punished, and whatever backstory we got not affecting him since his waifu was suffering
this thig annoys me so much that many authors that give villains sympathetic backstory never actually do it properly. it always contradict with how they achieve their seemingly "good" goals. you can be sure its not going to change MC action in punishing her in the end due to how over the top the villains act in early story.
but then again, if she is actually thorough with her plan (not sacrificing or not going too far in hurting other) then who's going to be the antagonist of the story
