Paolini did admit that Eragon was a chosen one. But he also said that he was trying to play with the idea of destiny and prophecy by having someone learn that they were going to do something and then killing themselves so that they wouldn't. I don't remember that. But whatever.
Wat? When has Eragon ever, ever, EVER contemplated killing himself? The hell?

You've been touched by the devil. You must wash.
