"Now I believe it is by the laws of heaven that man must live." * Haemon says this to his father to show that he once sided with Creon, but has now reconsidered. The Sentry said this to Creon because the Sentry allowed someone to bury Polynices. Creon said this at the end of the story when he realized that he was wrong and experienced catharsis. Ismene said this to Creon when she changed her mind and insisted on dying with Antigone.

Creon said this at the end of the story when he realized that he was wrong and experienced catharsis.

Explanation:

In the story 'Antigone', Creon decided to release Antigone from the prison and set up a tomb for Oedipus because the oracle Teiresias prophesied great suffering if Creon didn't undo his wrong doings.

After being convinced by Chorus and the prophecy foretold by Teiresias, Creon remarks the words "It is by the laws of heaven that man must live" at the end of the story to amend his misdeeds. He realized that it was wrong to take Antigone's life because it was against the laws of heaven.
