Throughout Nwoye life he has had Identity/cultures problems with himself. He does not wish to be like his father. He does not fit in with his culture. When the white men came with their culture Nwoye joined them.
He does not wish to be like his father. His father uses violence to get his way. Okonkwo beat his wives when they do something he does not want. Okonkwo wants his son to be a man so he uses fear to get him to do what he wants. When Nwoye joined the new culture his father beat him then tried to choke him.
He does not fit in with own his culture. He wonders why his clan does these killings. When his father comes home after he killed Nwoye friend something breaks in his heart. He does not like it when the clan kills
