Does Creon give a proper burial to Polynices in the end?

No, Creon does not give a proper burial to Polynices in the end. Despite the pleas of Antigone and even the intervention of the blind seer Tiresias, Creon remains steadfast in his decision to leave Polynices' body unburied and exposed to the elements as punishment for his treachery against Thebes. This defiance of the gods' laws and natural customs ultimately leads to Creon's downfall and the deaths of his son Haemon and wife Eurydice.
