Antigone in a sense is about the evil that good people do.
Antigone, a play written by Sophocles in the 5th century B.C., is a play enclosed by conflict and problems. Conflicts are evident from the beginning of the play, to the end. Even before the play has even begun, these problems are already evident in the history of the characters in the play. Oedipus for instance had killed his own father and married his mother. Although he was not aware of that fact, this results in Jacasta hanging herself, and Oedipus blinding himself. Their two twin sons, Eteocles and Polynices agree to rule in alternate years, but Eteocles refused to relinquish his rule of Thebes, and as a result Polynices fled to Argos to gain the aid of the Argive army. Polynices and the Argive army attacked the seven gates of Thebes, and the two twins ended up in killing each other.
Also, evil is a common factor in this play. If it were not for the evil within Eteocles, then the brothers would not have slayed one another. Furthermore, when Creon gains royal power he refuses to give Eteocles, his nephew, a proper burial and leaves him unburied to rot and get eaten by the animals. As for Polynices, he shall receive all the proper burial rituals. This makes Antigone very mad, as they are both her brothers, and she believes they both should be buried. Although Creon is royalty and is seen to be a good person and respected ruler, when he is angered, his anger blinds him, and the actions he takes portray some evil.
When Creon gains power over Thebes, as closest relative to the dead King, he proves to be a great ruler who cares about the right being of his city and townspeople.
