Question: who did okonkwo kill in the end?
Answer: Okonkwo's gun accidentally goes off and kills Ezeudu's sixteen-year-old son. Killing a clansman is a crime against the earth goddess, so Okonkwo must atone by taking his family into exile for seven years. Okonkwo gathers his most valuable belongings and takes his family to his mother's natal village, Mbanta.
