Basically, everyone is selfish and even though they suffered a bunch, they decided to hurt others. The Devil, Judan, Yuha and Jiyul kept thinking "he don't understand me", but they didn't try to communicate and thought they suffered the most. I really loved Mugi, even though he did it all because of revenge instead of his supposed "loyalty" to the Han country, he did his best.
