How is Oedipus seen as a Greek tragic hero? Give 3 reasons why and state evidence.

"Oedipus, the main character of the drama, is a great king with ideal traits in his individual personality also; but he is tragic due to a tragic flaw in terms of his moral disposition. That mixture makes us have the tragic experience of catharsis at the end of the drama when all the good of Oedipus is 'wasted' in his struggle against the bad."
