Aside from the huge dick, we have got some interesting information to add to the bucket of (cu-!) information.
1. Guwon may be acting a lot of the time in front of people/humans. It seems he knows on a basic level that there are good and bad things, but he doesn't really know how to react appropriately to each situation or how to choose between morally ambiguous situations. It seems because of how he is as a person (huge, intimidating, strong) people tend to be scared of him, so they generally don't want to upset him - like when Teach first met Guwon, he did all he could to try and not be killed by Guwon. This creates a dynamic where the townspeople don't necessarily question Guwon on his actions because they risk becoming a problem that Guwon may want to get rid of. This is important because, although somewhat cruelly, the town has survived for so long because it follows the rules and follows the limits. Generally I think Guwon is acting because he wants someone to guide him, and so far the townspeople have been rightfully too scared to really do anything about it. Now he has Teach, who can guide him but the real question is if Teach should guide him. It is true that being too emotional in high stake situations can be bad, but it is also human nature to care - can Teach actually guide Guwon with nuance or will Guwon learn the wrong lessons? Another minor point is that Guwon gave Teach the necklace/ring but he isn't bothered by the necklace being abandoned - which shows that perhaps what Guwon said about the ring is something he heard not necessarily believes.
2. Teach is in love with Guwon, but Guwon is NOT in love with Teach. I think so far we have confirmation that Teach did fall in love, however Guwon feels something more like attraction or interest not actual love. This goes with my idea of Guwon acting because he doesn't know how to be human. For now Guwon is interested in Teach as a moral guide and teacher, that does not signal love although that could change, we just don't know yet. This is confirmed because of 2 things: Guwon wasn't even worried about the necklace/ring being abandoned (even when he said it was something that proved Teach was his only one, seems like little care was given to such an object being left behind) and Guwon still lusting and hoping to fuck Teach. It seemed like Guwon understood that Teach was upset, but that is pushed aside because he wants to fuck Teach and depending on if Guwon tries to force Teach or not, it will prove Guwon is morally 1 dimensional. Like I would be questioning what to do if someone told me they hated me because of my actions, not wanting to fuck them. But that only goes to show that Guwon is possibly not human or at least some sort of experiment that has difficulty understanding morality.
3. Everyone is lying but it's not necessarily because they're evil. Before I was 50/50 about the Doctor lying and now I'm closer to 80/20. He said that Guwon killed his wife and kids, but Guwon confirmed that there were more kids before who died although they tried to give them medicine and help them. So either the Doctor arrived after changes were made (meaning no more waste of medicine/no more extra people allowed) or the Doctor purposefully lied to Teach to get him emotional enough to want to help the kid and talk to Guwon. I think the Doctor was one of the old owners at the village (because of an earlier conversation with Teach) so it wouldn't make sense that his wife and kids were killed, but it's entirely possibly that they were outside of the village when everything went to hell and the Doctor did see his wife and children die. I also don't think it's out of real malice, but necessity to live and save others. Although it is scummy to hide behind Teach, who will have to bear the consequences.
