Some literacy critics have defined tragedy as "the downfall of a hero." Would Aristotle agree? How might he revise this definition?

Aristotle‘s ideas about drama were based on a generally Greek belief that tragedy was the highest form of drama. He said that tragedy is an imitation of an action that is serious. Moreover, he expected the drama to cause the feeling of the pity and fear that are to cause the catharsis - the purification of emotions. Thus, in Aristotelian perspective, tragedy tells about the high deeds or feeling of a man.
