Heroes and the Defiance of Fate
As tragic Heroes influenced by fate, Achilles and Oedipus both share a fatal flaw that eventually leads to their demise, though there are also numerous differences between their myths. No matter what these two heros do, the choices and decisions that they make will lead to there downfall. Even if they believe that they are cheating their way out of it, they actually set the path for their pre-ordained fate.

The great Achilles of Greece is known as the greatest warrior in the Achain Army. Still, this mightiest of warriors cannot escape his own tragic fate. His own choices and decisions guide his fate, and fate guides his decisions to an end that he cannot escape. When Achilles decides not to fight, his closest friend, Patrolelos, dresses in Achilles armor to boost the morale of the Greek Army. But, Patrolelos ends up getting killed by Hector. This sets in motion a series of fateful revelations and decisions that lead to Achilles fatal flaw. Achilles Mother, the goddess Thefis, tells her son that he will die if he avenges the death of his dear frioend and kills Hector. But Patrolelos is more than a dear friend. He is also a reflection of Achilles glory and in an emotional sense a part of him. So in every way, Patrolelos death is a direct blow to Achilles, and Achilles has no choice, being the great warrior, but to seek revenge. His decision guides fate, but at the same time, fate guides his decision. [ From one point of view, we see that Achilles chooses not to fight of his own free will and we see that Patrolelos chooses to masquearade in Achilles armor by his own free will. From another point of view, we see that fate guided these two friends to make these fatally flawed and fateful decisions.] We must also understand that Achilles is selfish and full of himself and could care less about the forces of fate. He thought of himself as invincible. In spite of the warning from his Mother, Achilles chooses to continue his plan for revenge and certain death. Fate knew all along that Achilles ego would take care of the rest.

In contrast to Achilles who charged boldly into his fate, Oedipus tries to run away from his fate, but the outcome is the same. Though Oedipus tries to run away from his fate, he ends up running right into it without even knowing it. Quote an oracle. The great King Oedipus of Theba was probably the greatest Greek King of all time. He was an honored hero to the people of Thebes, but not even this great King and hero could escape his fate. At birth, an orcale informs Oedipus parents, the King and Queen of Thebes that their son will kill his father and marry his mother. In dispair, the parents banish their son and leave him to die on a mountain top. He is rescued and raised by the King and Queen of Corinth with no knowledge of his true heritage. In a fateful encounter on the road to Corinth, Oedipus meets a rude and mean stranger and ends up killing him; the stranger is his father. Shortly after reaching Thebes, Oedipus is crowned King and takes as his wife the widowed Queen - his mother . His decision guides fate, but at the same time, fate guides his decision From one point of view, we see that Oedipus chooses to fight of his own free will and we see that the people of Thebes choose to to make him eKing of their own free will. From another point of view, we see that fate guided Oedipus and the people of Thebes to make these fatally flawed and fateful decisions.]
