Curiosity: Oedipus' insatiable curiosity and desire for knowledge drove him to seek out the truth about his past, even though it eventually led to his tragic fate. He could not resist the temptation to uncover the secrets of his birth and parentage, even though it meant confronting painful realities.
Anger and Impulsiveness: Oedipus' quick temper and impulsive actions often got the best of him. His tendency to react emotionally and without thinking through the consequences led him to make rash decisions that ultimately contributed to his downfall. For example, he killed a man in a fit of anger without knowing that he was his own father.
Blindness: Oedipus' physical blindness, which was a punishment for his actions, also contributed to his downfall. He was unable to see the true nature of his situation and the people around him, which led him to make mistakes that ultimately sealed his fate.
In summary, Oedipus' tragic flaw was a combination of hubris, curiosity, anger, impulsiveness, and blindness. These flaws led him to make choices that ultimately resulted in his downfall and the tragic consequences that befell him and his family.
