Final answer:
The Chorus in Greek tragedy, such as in Sophocles' Antigone, underscores the evil that can be found in tragedy, which often involves moral choices and ethical dilemmas leading to a character's downfall.
Step-by-step explanation:
The Chorus in Greek tragedy often comments on the morality of the characters and the unfolding events. In relation to Antigone and Creon's situation, the Chorus highlights the evil present within the realm of tragedy. This is a clear reference to the classic definition of tragedy as a literary genre where a protagonist, typically of noble birth like Creon, faces ethical dilemmas with high stakes, often resulting in a downfall due to a personal flaw or hamartia.
In Sophocles' Antigone, the Chorus serves to critique the actions of the characters, reflecting the overarching sense of morality that tragedy seeks to examine.
