What are the motifs in Antigone by Sophocles?

The perils of pride are a recurring idea. At the conclusion of the play, following the deaths of Haemon and Eurydice and Creon’s realization that their deaths are at least in part a result of his arrogant determination to see the law obeyed, the Chorus comments that “great words by men of pride bring greater blows upon them”. In other words, they are reiterating what Creon has already realized, and commented upon in his lament to the gods.
