This woman is mentally unstable and I can guess spoiled from the time she was young expecting others to worship her. If rejected, she goes crazy and I have a feeling that was the case with the father who end up in an arranged marriage with a woman he never wanted, fell in love with someone else. Moyu is a reminder of that rejection and hate. I stated in a previous post that its possible that she killed Moyu's birth mother and twin. Its a definite.
