How does fear and identity drive okonkwo?

In Chinua Achebe's "Things Fall Apart," Okonkwo is driven by a profound fear of becoming like his father, whom he views as weak and unsuccessful. This fear compels him to adopt a hyper-masculine identity, emphasizing strength, stoicism, and success in order to assert his place in Igbo society. His obsession with maintaining this identity ultimately leads to his tragic downfall, as he becomes increasingly isolated and unable to adapt to changing circumstances. Okonkwo's internal struggle highlights the conflict between personal identity and societal expectations.
