How does okonkwo overcome the tragedy of losing his first son to christianity?

Okonkwo is a self-made, well-respected member of the Umuofia clan. Though outwardly stern and powerful, much of his life is dictated by internal fear. His greatest, overwhelming worry is that he will become like his father – lazy, unable to support his family, and cowardly. Okonkwo considers many of his father’s characteristics to be feminine. Much of Okonkwo’s behavior results from a reactionary desire to be completely unlike his father. This means that Okonkwo attempts to work hard, provide for his family materially, be brave, and be masculine in every possible way. As a result, Okonkwo’s becomes successful in many ways – he becomes very wealthy, holds a high-ranked position in the community, has three wives, and is known for his skill as a wrestler and warrior. But he also tends toward emotions that are extreme, and his fear motivates him to take actions which are often unnecessary and ultimately destructive. His fear of being feminine leads him to assist in the murder of Ikemefuna whom he loved, to beat his wives, be emotionally distant from his children, and to disown his oldest son.

As an uncompromising man’s man, Okonkwo’s relationship towards his family is one of complete dictatorship. His three wives are there to serve him his food and raise his children. By seeing them as his subjects, Okonkwo can justify his brutal behavior against them. He can beat his wives without guilt. He can threaten Ekwefi with a gun when she talks back. He can rebuke Nwoye for listening to old wives’ tales. This sense of ownership is exemplified when Okonkwo takes Ikemefuna’s life. Though he does have qualms about killing Ikemefuna, they are not qualms about whether or not he has the right to do it. Okonkwo feels complete ownership over his family.
