1.) Was McMurphy honestly caring towards the ward patients, or were his motives purely selfish?
He cared about the patients, but he saw that he had opportunities to make quick money a few times in the story, so he took it. At the same time though, I saw he frequently let the patients win back their money, and he didn't con as much money from the patients as he could have. Especially at the end when he turned against the black boys, he didn't do that for himself, he did it to stand up for the patients.
2.) How was Chief able to control himself from letting on that he could actually hear?
Chief was actually crazy. It was part of him being insane that at times he could probably convince himself he was deaf; so he never spoke up or showed signs that he could hear what people said.
3.) Why was Chief chosen as the narrator?
Chief was narrator because he could see both sides of the story. Since people never had any filter around Chief because they thought he was deaf, he heard everything. He was to see how people really were at heart, and make fair assumptions of people like Big Nurse.
4.) What did Chief's fog represent?
the fog was Chief's way of blocking out what upset him.For example, when he thought he was going to shock therapy at the beginning of the book, the smoke came in to block it out. As the book progresses the fog becomes less frequent, showing that Chief is becoming more brave.
