Discussions about the gods

Can anyone explain the idea of the gods in the story? Not the dragons warriors the dragons themselves.

At the beginning of the story, we find that the people of Kouka worship them. The first king of kouka made made il the next king because he was the father of yona king Hiryuu reincarnation. That was the beginning of the stubid decisions. Yuhon hated the priests and gods and as result killed the priests and his brother wife which was extra stubid King il killed his brother and treated his nephew badly because he worship them.

in the beginning of the manga the gods was spotted as great. But after the last events, the gods appeared to be extremely selfish they just want be with the crimson dragon.

Well after the last chapters I can't stop thinking that SooWon was right.
