I mean yeah, I don't really understand how he would really fix that though, he really isn't in the most ideal world for a girl like her, after all shes a miracle, anyone would 100% take advantage of her and abuse her for their own growth, you have to look at this from his POV, what can he do to protect his literal "daughter", what can he do to prevent her from being abused by unfaithful people? There's no real way he can do any of that in the most ideal way unless he quite literally the pinnacle of power in his world, but he isn't, he's getting stronger but you still see the dude fumble and get tossed around.
All I'm saying is that, he is really trying his best to keep her and himself safe from the unknown horrors that she can truly bring, and that's really the best your going to get.
