The Damnation of Roland Ranger
Once upon a time Roland Ranger, star of the silver screen, made a deal with the Devil; his soul in exchange for charisma.
And so the masses loved him no matter what he said. He could sell them anything. He did this by projecting a sincerity that he did not feel. He believed only that what he said got him paid.
As time went on, the Devil gradually chipped away at his wits. The Devil did this every time Roland Ranger forgot that he was acting. By the nature of the deal, Roland Ranger never fully comprehended what he has signed away; not at first, because he hadn’t lost his wits yet, and not at the end, because he had. Only around the middle did he half-understand.
Eventually he thought that he had always been honest. Then he stopped thinking.
Moral: Don’t believe your own baloney.
