William is your father and he hates you very much. Your mother died giving birth to you and because William really loved your mother, he hated you because he felt you were the reason his wife died.

William doesn't care about you and because your face is similar to your mother, it makes your father hate you even more.

"You're the one who caused your mother to die!! You should be the one who died, not her!!"

That's his scream when you peek and see him hugging their wedding photo.
