Why does the sentry return to creons palace?

Answer 1

The sentry returns to Creon’s palace to report the news that someone has buried Polynices, defying Creon's orders. He is apprehensive and fearful of the consequences, as he did not want to be the bearer of bad news. The sentry hopes to avoid punishment by bringing the information directly to Creon, highlighting his duty and the tension between following orders and the moral implications of those orders. His return signifies the mounting conflict between the law and individual conscience in the story.
