Honestly he only loves himself
I personally think he saw her as impressionable and naive, he thought he could use her to get pregnant, have and heir and then dispose of her, making Naiver his empress again. I don't think he loved her at all, it was all and act. Although, when Rashta started making stupid decisions did he really start to show how lowly he thought of her. All in all they're both crappy and deserve what has happen to them.
He felt like a god helping a poor woman in a poor situation. But the poor woman was only financially poor. So suddenly he hates her. Even though he brought this all to himself. He only thinks with his pride and his crotch
Just wondering, did he every truly love Rashta at some point or did he get involved with her for the sole purpose of an heir??
