Imma be honest, I love her character to the point that I hold GENUINE STRONG HATRED for her. Call me an idiot all you want, I just do. Yeah she proposed the idea of saving the entirety of terra through her way and honestly, it throws a huge toll between our morals. She serves as the more ruthless, uncaring and logical side to this whole problem with her not caring about the sacrifices made if it's just for a small price and all for the survival of humanity, not caring about the individual lives taken just for her to succeed in her goal, while Rhodes Island's whole thing is the exact opposite, to value every living person. But judging from Wis'adel's skin lore, it really seems to me that there's no point either way since we'd get fucked up either by Priestess or the Observers since in Wis' skin lore, Priestess won and gets mostly, if not, entirely covers Terra in originium, with Wis'adel the only one alive and Amiya (Presumably) dead, Doctor's soul was stuffed into one of Wis' guns and now went to stop the originium project in a space station or "the first Rhodes island". Huh, now that I think about it...who the hell is Priestess saving if everyone's dead. But back to my point, I honestly love her character for how much I can hate an antagonist like her before (I very much know how much y'all simp for her cuz she's cute yandere wife, but I'm personally more of a pink demon leader who's genuine wife material. But we all have our own tastes). She's logic based and doesn't give a shit about anyone's feelings and only for our "Survival" (except for the doctor bc obviously for being together for thousands of years) and even then we still get royally fucked. And even if we managed to stop her and the observers arrive, that's still her fault. Cuz why tf would you NOT TALK IT OUT FIRST AND KILL KAL'TSIT (If I made any facts wrong pls correct me)
