I think that is his charm. His impulsiveness, his naivety, his ignorance. He's not smart, but isn't stupid. And he's greedy and overly cautious all at the same time. All of these things you can work with if you have the right tools to mold him. He has the strength and the experience to back himself up, he just lacks forethought and courage... most likely due to insecurity and depression. He's lived his life in surplus and all of that has lead him to nothing, which the advisor had pointed out a few chapters ago telling him to give all of his divine relics away he has no need of them. (The advisor included if you think of the advisor as a "relic".) So what the advisor and the 2nd young master are trying to tell him or at least for him to realize is that he has worth he just needs to let go of some things to see it. Bc he can sit dignified and proud on his throne but ultimately he chose the chains to shackle himself with. They are literally just telling him to use the key to unlock the chains.

Idk i really cant get myself to like the sky heaven cult leader. His low iq is too annoying he really cant think for himself?
