The quote "If you fuck you, you have the right to yell. And since we fucked!" from Ken Kesey's "One Flew Over the Cuckoo's Nest" embodies a notion of accountability and expression. It suggests that if individuals are responsible for their own situations or actions, they should be able to voice their frustrations. This highlights the theme of personal agency within the narrative, particularly in a setting where characters struggle against oppressive systems.

In the context of the novel, this line reflects the protagonist's rebellious spirit and the larger struggle against authority. It implies that through conflict and struggle, there comes a rightful empowerment to speak out against injustices. This dynamic emphasizes the importance of individual voice and the need for confrontation in the face of oppressive forces, resonating with the overall message of defiance and self-assertion in Kesey's work.
