Answer:
In Chinua Achebe's "Things Fall Apart," Okonkwo initially develops affection for his adopted son Ikemefuna. Despite being initially forced upon Okonkwo's household as a peace settlement, Ikemefuna becomes like a son to Okonkwo. Okonkwo appreciates Ikemefuna's hard work, obedience, and growing maturity. He even sees in Ikemefuna the potential for greatness and hopes that he can mold him into a strong and successful young man.
However, as the story progresses, Okonkwo's feelings towards Ikemefuna become complicated. Due to the tragic turn of events, Okonkwo is forced to participate in Ikemefuna's execution, an act that deeply affects him. Okonkwo's conflicting emotions of love and duty ultimately lead to his involvement in the tragedy, and he feels a great deal of remorse and sadness for the loss of Ikemefuna.
Overall, Okonkwo's feelings towards Ikemefuna evolve from initial acceptance and fondness to conflicting emotions of attachment and guilt, ultimately resulting in a sense of sorrow and regret.
