When we’re hit by dissonance–a symptom of our personal belief systems failing to produce an expected result–I believe we are faced with a choice: backtrack and adjust, or cling to the ego-borne notion that we’re still on the right path.
From what I understand, the hero will do enough of the former to mitigate however much (s)he indulges in the latter. The villain will do the opposite. Wisdom come from knowing that both can (and probably will) lose their way, and that both can find it.
