The case of Oedipus, I do not see how it captures your idea. You are taking a work of art literally. What happens when you apply that to religion? Were the children of Adam and Eve incestious? There were art healing centres in ancinet Greece the were caleld Asklipia and they were attached to the theatres. They used hipocratic medicine and also dream healing. They would watch a full day of comedy, and tragedy, then they would all sleep in a big room where they burned some incense laced with hallucinogens and the god of Medicine Asklipios would appear in their dreams and heal them. Original sin as idea in a religious sense is a better example of fatal flaw or original sin don't you think?
