I: What did McMurphy symbolize?
A: I believe McMurphy was the christ-like symbol in the novel. He was working for the others to create greater lives for them, and he was symbolized as Christ specifically in the electric shock room. He died a martyr to the others, and that further concurs with the christ symbolism.
E: Was it effective to use Chief as the narrator?
A: Yes it was for several reasons. First of all, the fact that he was introverted it made him a character that could listen to conversations on both sides. This made him useful in telling a non-bias story. It also helps having Chief as the narrator because he shows change over the course of the story due to McMurphy which makes the audience like McMurphy more.

E: What was McMurphy's motive for helping the other patients?
