To bring arise to our discussion on how McMurphy serves as a Christ figure, I've noted some things that support the idea. He performs "miracles" of some sort, getting Chief to speak to him, as well as stop Billy from stuttering briefly. Also, before he plans to escapes, McMurphy throws a sort of Last Supper party for the men. I see this story so far as the story of Jesus from the eyes of one of the apostles, the apostle being the Chief, for he narrates the story.
