Nothing Matters

Before Oedipus, a mythical Greek king of Thebes, was burn the Oracle of Delphi told King Laius of Thebes that he'd have a child who's destined to kill him and sleep with Laius's wife, Jocasta, the boy's mother.
When the baby is born, the king leaves him in a moutainside to die; However, A shepherd finds the baby, though, and takes him to King Polybus and Queen Merope of Corinth, who name him Oedipus and raise him as their own.
One day he goes to the Oracle of Delphi to find out who his real parents was. She didn't end up telling him who were his patents, but she told him about the Profecy. Hearing this he was terrified. Therefore, to avoid his destiny, he runs away from home.
On his way he got into a fight with an old man, and because answering a riddle of the Sphinx (the guardian of the city of Thebes) at the entrance of Thebes, he gets to marry the queen Jocasta and raised four children with her: Polynices, Eteocles, Antigone, and Ismene.
He eventually found out that the man whom he had killed was his father, King Laius and he had married his wife, Jocasta. He fulfilled the prophecy that everyone had tried to avoid.
This legends leads us to the question: "Do we really make our own choice? Or are we determined to end up that way?"
