The director situation kinda confusing, at first I thought they want to be a woman but then we see they got disgusted to be touched by their father as a 'woman'. I don't think we can really refer their gender yet, anyone who calls them he or she is not wrong because we definitely need to see more of their story
from my understanding i don't think they want to do that, but because they look so much like there dead mother. Its a request for when the father's not in his right mind to keep him happy til he dies. The disgust is understandable because his father is feeling on him like a lover. They don't have an identity outside of that
Man really go from getting revenge to a love sick puppy so quickly
