How does Nwoye's acceptance to the cultural collision shape the meaning of the work as a whole?

Towards the end of the novel, we witness the events by which Igbo society begins to fall apart. Religion is threatened, Umuofia loses its self-determination, and the very centers of tribal life are threatened. Nwoye is also not entirely sympathetic to Igbo culture. There are extreme patriarchal and misogynistic traits ingrained in the culture. What is certain is that the cultural clash would inevitably change Igbo life and culture forever.
