No, you are wrong, because as you can see, all people summoned to that world other than Koreans are either EVIL or INCOPETENT, only KOREANS are good, competent, awesome and have proper manners or culture. This is his point about racism in this novel, not about this certain dude and his deeds. Just look properly how other people are portrayed; English dude - incompetent fool, Chinese dude - evil schemer and..., Polish dude - pedoph**e, another guy with Polish surname - b*nd*g* master, Jewish guy necrop**e... Really, are you sure of your statement?
