One Flew Over The Cuckoo's Part Two

In part two of One Flew Over the Cuckoo's Nest, R.P. McMurphy goes through phases of rebellion under the control of Nurse Ratched. A major theme in this part, as in the rest of the book is control, as McMurphy struggles with the idea that Nurse Ratched can postpone his confinement indefinitly, while at first he submits to defeat after discovering this vital piece of intel, it becomes clear that he cannot live under the nurses rule for long, but his later rebellion is much more significant than his own personal agenda.
McMurphy has become a symbol for the other men on the ward, most notably Cheif Bromden and Billy Bibbit, who view him as the man come to take Nurse Ratched down a peg, and afford some more control to the patients of the ward. Therefore by continuing his struggle for control against the forces of rightful authority, he becomes more than just a crook, looking for away to live his life to the fullest inside an institution. He becomes someone fighting for the rights of the less spirited in the ward, the weak, the strong, the disturbed, and the meek, McMurphy is there to deliver them all from their own shortcomings.
