Yea like what if he's the one who killed his own dad but guwon doesn't say it to him because he doesn't think it's important at all?
I agree. I think this would certainly explain those flashbacks

I feel that the teach definitely had a violent past before the head trauma and is an unreliable narrator. His initial extreme reactions to violence feels like the images are triggering his memories, but he recovers from them way too fast for it to be a complete aversion. He is living in his truth and only his truth.
