What action has Okonkwo taken as regards the conflict between the egwugwu and the Reverend? How does Okonkwo feel about this new form of conflict? What are the consequences of these actions? How do they react at first?

I think this is similar to your last question. Okonkwo is pleased by the destruction of the church. At the clan meeting, he had urged the destruction of the church, the killing of the white man, and the exile of all the Christians. Though the clan decided only to destroy the church, Okonkwo is pleased that something was done. Okonkwo understands violence and is happy they are being aggressive against the white men.
