To me it's like that was the sacrifice they had to give in order for them to live/survive. They are in a zombie apocalypse so everything is not going to be sun shine and rainbows. Everything in their town has order to it and Guwon the main thing holding the town/order together so if Guwon is gone then everything is going to fall apart.
I don't understand why some comments are asking why dont the people just leave, I'm pretty sure this has been explained in the story already??
