Nah killing the mc father makes the story more fked up cause the MC is finally turning into a psycho can't you see him shifting and his feelings colliding both his fear and like is a total mess. Anw Guwon did say everyone is like a dog lol.
What's a lil patricide between lovers
Tbh even IF Guwon didn't kill his father, which we will see at some point, it wouldn't change the fact that Guwon is a bad guy. He killed people, he will continue killing people. He uses and plays with them like livestock. Of course killing the MC's father would deal even greater damage but even if he wouldn't have done it, Guwon still did things that go against Teach's morals and he would still be against it.
