No, these are two different things.
She doesn’t want to make waves because making waves will jeopardise her chances at Saintessing, and she does the bare minimum because… that’s who she is, I guess?
Considering you only need, what, 70%? in Spiritism to make it happen, I presume there’s a reasonable amount of mages who could actually do it. Literally anyone who’s not-quite-as-good at Spiritism as she is at Theurgy can do it. (also, goddamn you Ilya, you’re also great at Enchantment, how about teaming up to invisibility glyph all the kids out of there?)
The “let’s let half these people die” is before this. And after going “let’s let half these people die”, she doesn’t even have the guts to make the call about which half, foisting that decision on the MC.
She getting huffy when you ask why the Church is only sending one healer to deal with a plague because “there aren’t enough healers” (conveniently not mentioning that the reason there’s a scarcity of healers is because the Church she belongs to and supports hoards the knowledge on how to do it and actively hunts down any non-affiliated healer*, to the point that when Eli went around healing people during the first Moonvein plague the Church immediately inquisitoned itself trying to find out who was responsible for the knowledge leak) is just for bonus points.
*after ordaining Param and Salantira to murder everyone else who had the knowledge, of course
