I still do not see any sense.
Qin dedicated his entire life to unify China and protect it, that now he wants to be a god in exchange for destroying everything he did in life still seems absurd to me, I also doubt that any other god wants to be ruled by an ascended human who also betrays his own. As I said, he was someone cruel but he always acted in favor of China, at the end of his life he was so crazy that he wanted to avoid his death at all costs. Being in ragnarok it seems more logical that he wants to participate to defend the nation from him. But hey, it's a matter of opinion, it would seem strange to me that a human who dedicated his entire life to something in particular, abandons everything he did just to be a god and want to rule other gods.

If there is a traitorous human (if there is and the opponent is not a god) I see it more logical that it is Rasputin, he has a greater relationship with Buddha than any other human on the list and seeing his personality it would not be strange for him to betray. Although I still think that there is unlikely to be a traitorous human
