Throughout the life of Oedipus, we see the evolution of one a man who was born into a position of power. This fact that he was going to be a future king merited him an "insider" position. However, once the curse that Apollo created was put force, Oedipus immediately lost this position because he represented a threat, thus becoming an "outsider" position. An intriguing aspect of this situation is that Oedipus hadn’t yet even been able to make decision for himself. He was an insider and outsider without actions. As Oedipus lives life, he gradually (and with some luck) becomes an insider once again, but this time trough his own actions of solving the riddle. He leads a strong kingdom while king and represents perhaps the epitome of an "insider" to society. This lifestyle is seized in an instant after it is revealed that the king had indeed completed the curse and married his mother and killed his father. Just like that, the powerful king descends to rock bottom of the "outsider" role. Things that can be learned from Oedipus' story is that perhaps what make one an insider or outsider are generally not actions taken by an individual, but destiny and luck rather that determine one's presence in society.
