One thing is for sure. Even those who still insist saying Emet-Selch was an un-nuanced terrible character despite all his sympathetic traits simply because he would consider genocide as a means to enforce his ideals over ours, now have nowhere left to go -- because we just performed a genocide on another reality because we deemed their continued existence incompatible with our ideals of how existence should work. The game can sugarcoat it all it wants by throwing a few people patting us on the back and saying it's okay, I feel that was entirely NOT okay and we did not even try anything else first. Like, did we need to even completely erase them? They supposedly only used up aether while manifesting physically anyway, it really looked to me like they could have happily lived in virtual reality forever without bothering anyone. Especially after seeing the last dungeon. Our motivation was literally, "If our enemy is doing this to preserve the lives of her people, then if we kill all her people first, she won't have a reason to go through with it anymore." And then the writers forgot that was the point of that exercise and everything went ahead anyway so it wasn't even just unnecessary, it was full on meaningless.
