He would even angry during such a sacred week. "And when she returned he beat her very heavily. In his anger he had forgotten that it was the week of peace." (pg. 29)
He would get angry over simple things. "Okonkwo's second wife had merely cut off a few leaves off it to wrap some food, and she said so. Without further argument Okonkwo gave her a sound beating and left her and her only daughter weeping." (pg. 38)
People who seem weak make him lose his calmness and he resorts to anger. "Nwoye overheard it and burst into tears, whereupon his father beat him heavily." (pg. 57)
He's quick to anger. "'Is that enough?' she asked when she had poured in about half of the water in the bowl. 'A little more ... I said a little. Are you deaf?' Okonkwo roared at her." (pg. 85)
