I think that the book suggests that individuals must try to find their own way "to become good again." The idea here is that Hosseini's work suggests that the inner conflict that exists within the individual rests in the capacity to choose good over those forces which are not good. For example, Amir must wrestle with his own demons in terms of the desire "to become good again." He might not be able to do anything about the relationship and lives he ruined when he was younger, but he has a chance to resolve that inner conflict with seeking out Sohrab. Amir is able to take active steps to find his own path that resolves his inner conflict. Baba never fully addresses his inner conflict in terms of his own life and actions. He never divulges the relationship between Amir and Hassan. He dutifully goes about his work and does provide for his son. He does not abdicate his responsibility. However, his conflict is something that he is able to put aside, and not directly address. For Hosseini, there is not as much of a judgment here as much as there is a statement that all people have the capacity to be able to resolve the inner conflicts that most likely reside in the ability to choose good over bad, the propensity to forge relationships as opposed to severing them.
