As soon as the day broke, a large crowd of men from Ezeudu’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 again 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 Umuofia believe that killing a brother clansman is a sin against the earth – the provider of life, the matchless nurturer of life, and the ultimate mother. The village believes that the earth will turn against them if the sin isn’t atoned for.
