So let me get this straight.
A father, discovered his daughter "suddenly" became a psychopath (from his perspective), and she's harming his servants / workers, when left unchecked -- and he runs away under the promise to "heal her", while not restricting her authority, at all?
If she's labeled a saint, let her play the part of a saint. Dump her to the temple, go torture their people who defend her -- but why the fuck would he abandon his workers, and let his daughter terrorize the land, under HIS name, under HIS authority?
The dad is so incompetent, he's borderline malicious in his lack of forethought behavior.
P.S: Frankly, he's so incompetent, that I'm actually certain that the dad was written last-minute into the story, this screams of: "oh yeah I want to add a loving father to the picture, how do I asspull this into the story, uhhh...?"
