This is the question of questions for biblical faith. Paganism then, like secularism now, had no such doubt. Why should anyone expect justice in the world? The gods fought. They were indifferent to mankind. The universe was not moral. It was an arena of conflict. The strong win, the weak suffer, and the wise keep far from the fray. If there is no God or (what amounts to the same thing) many gods, there is no reason to expect justice. The question does not arise.
