I watched the film years back and was intrigued. I think he knew once he was put in solitary confinement that it changed him forever...He made up is own universe and rules out of his head, alone just to keep from going insane. Or maybe it made him insane. Anyway he's certainly a very interesting character. Maybe not one to look up to, but I do admire is ability to survie and thrive and even manage to get some world feedback from such a lone situation in confinement.
