Not only he witnessed that with his mother, but he was also abandoned by his father. Had to survive by all means when he's still a teenager, left US, went to America. He was psycho not just because of his mental illness alone but because he sees how people reacted towards it. Mental illness + some kind of twisted preconceived ideas about people in general
Here we go again... Are we still reading the same thing? While I do not condone Woohyeon's actions, you can't blame him everything for it. I know it sounds hypocrite but the man has APD (Anti-Social Personality Disorder). He did get diagnosed with it and had professional help but imo he needed someone to teach him what emotions are and how each of it feels. He does not understand what emotions are and their functions. He did have his mother but even his mother was having a hard time...now it seems like I'm making excuses. Anyway, to shorten it the ml has a mental disorder where he lacks empathy or does not understand emotions. Thus, he says or do the things he has been doing.
