Yeo-dam judge things from his perspective as a human, The Emperor did things as a Jin, he didn't understand what he did wrong because it was not wrong as a Jin.
Still, he may have had his reasons, and I get that they were too different and never communicated properly in their first life... However, even if it was a misunderstanding and a miscommunication... I still do not understand why Yeo-dam got back together with him. I mean wasn't he so traumatized? Real trauma cannot be reasoned with. Even if there was a reason, trauma cannot be easily erased just because you learned there was justifiable reason behind what happened to you.
