This foolish father acts like he's so pitiful for marrying the empress meanwhile he married her to use her family's power to become the emperor and then neglected her. Does it justify her raping him, absolutely not but he is a user. Used her family to get the position and get his rivals out of the way and now wants to care that she's offing rivals. She probably killed rishars parents and that's why he care cause he sure didn't care when his brothers were killed.
