In Oedipus the King the climax of the play is when he discovers that he is not the son of the rulers of a nieghboring country, but is a prince in the country he currently rules, and has married his mother. His wife (and mother) gouges her eyes out, and Oedipus blinds himself. The resolution is that he leaves the city, with only his daughter, Antigone, in search of a place to die. One of the main points of attack is that the gods control everything, and often quite cruelly.
Hope this helps some.
