Nwoye was seen associating with the Christians. After being threatened by Okonkwo, he joins the Christians and volunteered to go to Umuofia where a school had been set up to to teach young Christians literacy. Effectively, Nwoye had abandoned the gods of Okonwko and his fathers.

Answer 2

Nwoye's actions in converting to Christianity and ultimately rejecting his father's traditions and beliefs disturbed Okonkwo because he saw it as a betrayal of their family and Igbo heritage. Okonkwo believed that Nwoye's change represented a weakening of their clan's identity and a rejection of the values that he held dear.
