Oh he** no, self-fullfilling prophecy coupled with time travel, that's such a messy setting. He knows of the demon king in the future, then he goes back in time so there should be 2 demon kings, but if it was always only him as demon king then there was no demon king before, so he couldn't have known about the demon king in the future and wouldn't go back in time and all this wouldn't even kick off.
If you write about time travel you absolutely need to make sure that it follows the rules and makes sense, this is nothing an amateur webnovel writer should touch
@Tyrus no maybe its a time loop, so to explain he is the demon lord bit he is not at the same time. so before he become the demon lord he to travel back in time so he will get access to his power, then so on the story of betrayal and his death that only mean that his death is needed for him to be him.
i know this is not understandable but if you watch the episode where stuwy Griffin created the universe for the universe to create him and so on it is cartoon so you know
