Why did he kill/disabled himself?
Either I view the ending as a suicide or just getting rid of the "superpowers", I don't understand the significance of it.
He did seem to think that this knowledge of the name of god was given to him and that he's worthy of it. So why he gave it away? Couldn't he have used it to make the world a better place? Did he just gave up at the end? What does that tell us?
