I think if you look at it this way it will be clearer for you. First is the fact that the baby is both of theirs, so they should both have a say on what they decide to do whether that be abortion, giving birth, or something else. But the master took that choice into his own hands and decided it for himself. That’s where the problem happens. Yes his intentions were good, as he was worried for Hwan’s life, but it just wasn’t his choice to make, essentially on his own. Secondly, Hwan is the one that’s pregnant (when he wasn’t necessarily looking to be) and it’s his body, so he gets the only decision on if he is willing to take the risk of childbirth and maybe sacrifice his own life for their child’s. I think a lot of people are focusing on their fact that the master made this decision because of his desire to keep Hwan safe, but it just wasn’t his decision to make on his own. He should’ve been truthful with Hwan in the beginning.
They both have a point, I don't know which side to take. Guess I'll remain neutral?
