The final scene ends not only Antigone, but the entire sequence of tales in the Oedipus Trilogy. After this sad end, with Creon led off in despair, there will be no more possibilities — tragic or otherwise — for the House of Oedipus.
All the tragic events of the episode — Antigone's hanging, Haemon's suicide, the death of the queen — result from Creon's initial determination to ensure the stability of the city by punishing its enemy even after death, and his stubborn insistence on his orders, even when challenged on the grounds of divine law and human decency. Creon's change of heart comes too late to save anyone, but just in time to allow the proud king a last heartbreaking confrontation with his son. In this, fate seems to condemn Creon with particular — perhaps justified — harshness.
Modern readers may wonder why the climactic scene in the tomb is not dramatized on stage. Greek theatrical tradition demanded that scenes of violence be described rather than actually seen. The emphasis of the drama was on poetry and horrifying or shocking action would distract the audience from the power of the words spoken by the actors.
