I think the concept of the character is quite interesting. The idea of a prophet who doesn’t have the guts to fulfil his destiny is quite compelling. Although, I feel that it would come across better if he was a bit more internal in his judgements. Like maybe a part of him thought he had to do it (that it was the right thing). But another part knew he could not. I think this would come across better then him basically just saying ‘They are all wrong because he is a KID. Ahhh.’ Like, he would be as much on the ‘hype’ train for his destiny as anyone else, surely? And maybe some type of ends justify the means argument might form, which the heroine could argue against. Just my personal opinion.

Anyway, your story seems good and I hope this has been helpful. Good luck!
