I'll be honest, a lot of people are coping. And I don't blame them! This part of MSQ was SO rushed. You're completely right: they directly tell us it's just a copy multiple times, and also directly show us memory aether being physically removed from a corpse and show all the endless dissolving into the same aether when we delete/kill them. It's completely unambiguous both times and also directly contradictory. No one is gonna be happy trying to talk about this one, lol.
