I also don't understand the spirit hate. He distrusts humans (who doesn't), he knows that she was once abandoned by her family, and he knows how terribly humanity treats those with jeweled eyes. No shit he'd rather her be safe in the forest that in the mist of greedy humans. But he hasn't forced her to return to the forest because he respects her autonomy. That makes him a good guy who's ultimately concerned about her wellbeing.
Anyway, just let her call you dad dude, this uncle shit is confusing.
