As soon as the day broke, a large crowd of men from Ezedu’s quarter stormed Okonkwo’s compound, dressed in garbs of war. They set fire to his houses, demolished his red walls, killed his animals and destroyed his barn. It was the justice of the earth goddess, and they were merely her messengers. They had no hatred in their hearts against Okonkwo. His greatest friend, Obierika, was among them. They were merely cleansing the land which Okonkwo had polluted with the blood of a clansman. (13.15)
The gods are beings to be feared, respected, and appeased. Pleasing the gods is far more important than anything, even friendships.
