"How do you think we can fight when our own brothers have turned against us?"
After Okonkwo's seven year banishment, he finally returns to his home tribe, only to find out that it has changed completely due to the church that the white man has built. Enforcing rules of judicial systems and harsh rules, turning most of the tribesman on the white man's side. Angered, Okonkwo questions his clan, calling them cowards, only for them to use the quote above.
In my mind, Okonkwo seemed to think he was going to return back to his tribe and be the "top dog". Boy, was his vision shattered. I mean, the man spent seven years in banishment. He was anticipating this day for a LONG time.
Maybe he was a LITTLE more than anxious...
