How does Okonkwo jeopardize his own authority within his community?

Okonkwo does several things to do this:

• He is not humble, and puts down an agbala at a meeting.
• He breaks the week of peace by beating his wife. Further he is not repentant outwardly.
• He takes part in the killing of Ikemefuna, thus possibly committing an offense in the Goddess of the Earth's eyes.
• He accidentally kills Ekeudu's son, forcing himself into seven years of exile.
• He is unable to convince his son Nwoye to not convert to Christianity.
• He kills a kotma without the proper backup from the rest of his clan.
