Was McMurphy admirable? Dangerous? Both?

I like McMurphy: he is a bearer of truth, a Christ-figure or. He is only dangerous to Nurse Ratched and her obsessive control over these men. He  seems to care deeply about his fellow inmates, often putting justice and their well-being over his own desires to escape the institution--which inevitably costs him his sanity. McMurphy represents freedom and self-determination versus societal repression--a battle McMurphy ultimately loses in order to pave the way for the rest of the patients to see the light. In many ways, he becomes a sacrificial lamb for the sake of enlightenment and awakening, both within the novel and for readers. McMurphy's character is remembered as a martyr who inspires real-world social change.
