i really don't think that guwon was bad at all for killing the 'rat'
keep in mind how this is an apocalyptic situation where everyone can die at any moment, and from what we know so far the people that are keeping the rest of the town alive are called hounds.
if you were a hound, it makes sense that you would want preferential medical treatment when you're putting your life on the line for everyone else. and if you were everyone else, you'd also want the hounds to stay alive and well so that they can protect YOU.
in this situation, all rules are written in blood, and the rest of 'society' deemed that he ought to die. guwon was crying because he did NOT WANT to kill the 'rat,' but he had to do so to enforce the authority of the law so that everyone would keep obeying the rules, and thus, safe.
