Fairness on the Ward

The patients greatly rely on McMurphy for many things-confidence, fun, a leader, and even a scape goat.  But McMurphy is also using the patients for his advantage, as well.  He is slowly luring Chief out of his fog, and even getting him to speak so he can lift the control panel in the tub room.  He is also being permitted on a fishing trip because of his stronger power over some of the Acutes.  But is this a fair relationship or is one side taking more advantage of the other?
