Two sides of... well, maybe not exactly the same coin

Pretty sure it was God emperor but maybe it's children of dune. There's a decision Leto makes to stay in the Golden Path that Paul wouldn't take and it's around then we find out he wasn't dead.

Nah he pussed out like a bitch and ran away after he saw he had to become a worm with no dick to save humanity from itself and guarantee the species survival to the end of the universe and by running out when he did put mankind on a path twords extinction something his son Leto II latter does and calls out his father now a blind wandering priest for running away like a coward and all the stuff he had to fix because he chickened out halfway in. Leto became the worst tyrant in human history to guarantee our survival and none will thank him for it and rember him as a monster when he sacrificed his own humanity to guide mankind onto a path that saw our survival till the end of time Paul should have done this yet he lacked the courage to make such a sacrifice
