The Role of Fate/Free will/ fate &character  in Sophocles Oedipus Rex

Oedipus Rex is one of the greatest creations of Sophocles where king Oedipus is the protagonist who is the victim of his own fate.
Jocasta and Laius attempt to get rid of their son but fate triumphs.
Oedipus is the son of king Laius and queen Jocasta. They hear from an astrologer that, Oedipus will kill his father and marry his mother. Thats why they tie his legs with a strong roof and order a shepherd to keep him on the pick of the mountain so that the beasts of the mountain eat him. Shepherd takes pity to him. The shepherd gives Oedipus to another shepherd who is the member of another kingdom. He takes it and shows him to his king. The king has no child so he becomes very happy to get Oedipus. He and his wife take great care as their child.
Oedipus fate takes him back to Thebes
When Oedipus is young enough, one day he hears from another astrologer that he will kill his father and marry his mother. At that time he does not know his real identity, he thinks that Polybus is his father. So he does not want to kill his father and marry his mother. At that time he leaves the country to get rid of the worse work. He returns to his own country but he does not know that it is his own country. It is the creation of destiny.
His fate ends up kiling his father and marrying his mother
While coming back to Thebes, Oedipus kills a man old enough to be his father .After that Oedipus meets with a sphinx which is a monster. It asks a question to the people but everybody fails to give the correct answer and when they fail to give the correct answer it eats him/her. He also asks Oedipus the same question but he gives the correct answer and the sphinx jumps from the mountain and dies. When the people of that country have learnt about the greatest success of Oedipus they become happy to Oedipus and as a gift they give their queen to Oedipus as their king was killed  and he marries a woman that was his monther ,without even doubting his wits.Here we observe that destiny has totally won and the fate has proved that no man can deny his sorrow and suffering.
Searching  ''murderer of the king Laius''
Oedipus is ignorant to the fact that by searching for the killer he is sealing his own fate.Oedipus believes by search for Laiuss killer he is using his own free will but that is not the case.Not knowing he was the murderer.Discovering he is the killer, Oedipus blinds himself and is exiled from Thebes.
Coclusion:
In this tragedy it becomes true. Oedipus has been trying his best to deny his fate and save him from the worse sin but he fails because his destiny bounds him to do so. Oedipus has failed and fate has won. So the role of fate on Oedipus is almighty.
