What is a real man?

Q: What does Okonkwo's reaction to the death of Ikemefuna say about his inner struggle with being a "real man?"

  The fact is Okonkwo has been so intent on being what he deems to be a real man that he would kill someone to prove it. Fear took over him and he did what came naturally to him- he killed his adopted son, so to speak. Okonkwo did it so that he would not appear to be weak and cowardly like his father. Earlier in the book, the author stated that Okonkwo sought to be the exact opposite of his father in every way. His father was kind, vulnerable, and showed his emotions fully. On the other hand, Okonkwo hid behind a facade.
    Okonkwo has defined a real man as a man who is completely opposite of his father. This is not only wrong, but extremely detrimental to Okonkwo's mental health. Was it any wonder that he was so guilt ridden and distressed after murdering his son? Okonkwo believed that to grieve was to be weak, to be a woman. A woman, the name his father was called. He tried to drink his problems away like most people today do. And, as most people today know, it does not work. Okonkwo did not want to admit that he was grieving over the death of his son and that he felt guilty for killing him because I don't think he could deal with the consequences of not only his actions but of what his father had done to his morality. Okonkwo began to question the one thing he had built his entire life around: being a real man. And, when he realized that his dependency just may be flawed, it caused him to create another perception of reality, a reality where he did not feel anything after his son's death. Okonkwo realized that he did not want to be cold. He just wanted to be the man his father never was.
