Okonkwo bases his self-worth on what other people think of him rather than following his own conscience. After he is asked to adopt Ikemefuna, a prisoner of war, Okonkwo comes to love him more than he loves his own son, Nwoye, who he considers weak. Okonkwo considers Ikemefuna honorable and hardworking. However, when the oracle decrees that it is time to kill Ikemefuna, Okonkwo does not do anything to protect him. Though Ikemefuna calls out to Okonkwo for help, Okonkwo kills him. Okonkwo is petrified of seeming afraid in front of other people because his father was deemed effeminate and weak. By attempting to seem strong in all circumstances, Okonkwo negates his own conscience. In the end, he suffers as a result, and he cannot ever reconcile himself to his biological son, Nwoye.
