The Nurse's practices, treatment or torture?

Nurse Ratched definately does not have positive motives in mind when dealing with McMurphy. She has had enough with him , she is fed up and she is trying everything to stay in control and keep power at the ward. She uses shock treatment as more of a torture than an actual treatment. It is also very interesting that the little japanese nurse in the Disturbed Ward does not agree with the Big Nurse's practices. The doctor's seem like they want to fight back against her as well, for instance, the Doctor goes against the nurse and goes with the men on the fishing trip. The reason no one takes over is because they are afraid of her, she runs her entire Ward solely on fear. Mcmurphy is the first one to break down her barrier because he is not afraid of her.
