thoughts that keep me awake at night: what IS the price of ressurection?

because John specifically says that he brought people back once, and he can never do it again, because the price was too great. and he is a liar liar pants on fire but like. something about that rings true to me. so what IS that price? the 10 billion were already dead, so there wasnt any kind of sacrifice needed. John himself ostensibly got off scott free, with an immortal body and the power of God to boot. The Ressurection Beasts can’t kill him, any fear he pretended to have of them was a lie. Blood of Eden might threaten his empire, but i cannot imagime them being any real personal danger to the King Undying.

im deeply fascinated by that conversation he had w Harrow where he told her that her parents had commited a type of ressurection. commited being the operative word – why is it a sin to bring back the dead? what is the price? what is the consequence? is it inherently related to massacre, like how Harrow’s parents only ressurected the souls that they themselves had just killed? is that what John did? did John kill the 10 billion? is the price of ressurection that you have to kill them first? but then what is the POINT of it? did he, like Harrow’s parents, want to create necromancers? that doesn’t any make sense purely on the cost benefit analysis of the utter destruction and loss of skills, culture, etc that must have preceeded the ressurection. people dying, especially on a “everyone on earth” scale, is generally considered bad by basically everyone. so how could reversing that be immoral? Tamsyn Muir is way too careful with her word choice for it to je an accident. so why is ressurection something to be committed?

i do not think that these are a questions that can be answered with the information we have avalible to us right now, but i am aggressively turning it all around in my head like a microwave.
