According to the book, Oknokwo's whole life was dominated by fear. Explain this statement. (chapter 2)

Here is a quote from the book that explains this:

Perhaps down in his heart Okonkwo was not a cruel man. But his whole life was dominated by fear, the fear of failure and of weakness. It was deeper and more intimate than the fear of evil and capricious gods and of magic, the fear of the forest, and of nature, malevolent, red in tooth and claw. Okonkwo’s fear was greater than these. It was not external, but lay deep within himself. It was the fear of himself, lest he should be found to resemble his father. Even as a little boy he had resented his father’s failure and weakness, and even now he still remembered how he had suffered when a playmate had told him that his father was agbala. That was how Okonkwo first came to know that agbala was not only another name for a woman, it could also mean a man who had taken to title. And so Okonkwo was ruled by one passion – to hate everything that his father Unoka had loved. One of those things was gentleness and another was idleness. ch 2
