His fate was predicted as something that if he continuously hate something he will destroy it. And the world tree is already turning him in to warrior as the fairy kings word. Warrior is destined to kill the Demon King and the demon king is same as the emperor that wants to die but cant die on their own.
Its just sad that whatever choice he makes will break him ╥﹏╥
What I am thinking rn is probably he'll kill the two rulers and then the new emperor might be the prince and the ruler of the demon world is him. Not sure but my gut is telling me that and the world tree also watches him.
