Final answer:
McMurphy is distinct from other mental ward patients due to his rebellious spirit and his refusal to conform to the oppressive institutional system.
Step-by-step explanation:
In the context of literary characters, McMurphy from "One Flew Over the Cuckoo's Nest" by Ken Kesey is notably different from most of the other patients in the mental ward. McMurphy's distinctiveness lies in his nonconformity, his rebellious spirit, and his ability to challenge the oppressive system of the institution, personified by Nurse Ratched. Unlike the other patients who have been subdued by the routine and rules, McMurphy maintains his individuality and often inspires others to rediscover their autonomy and courage.
