Final answer:
Oedipus's decision to have the Oracle's message announced publicly rather than in private shows that he values transparency with his citizens and aims to foster trust as a leader, adhering to the traits of the ideal Greek Hero.
Step-by-step explanation:
Oedipus tells Creon to make his announcement about what the Oracle has said in front of the citizens rather than in private, highlighting his commitment to transparency and public trust. This choice reflects Oedipus's character as a leader who values the well-being and the inclusion of his people in the affairs of the state. His willingness to openly address serious matters suggests that he seeks to foster trust and demonstrate his dedication to solving the city's problems, in this case, the plague decimating Thebes. Additionally, by handling issues in a public forum, Oedipus reiterates his role as the Greek Hero, adhering to the ideals upheld by Sophocles, that the hero, despite any personal flaws, must take responsibility and be an exemplary figure for the people.
Aristotle's concept of the Greek hero, coupled with Sophocles's understanding of human response to divine actions, emphasizes that the protagonist, while virtuous, is not without faults. By making announcements publicly, Oedipus also substantiates his intent to operate in a manner consistent with the expectations of a leader, as perceived by the citizens of Athens, who represented the typical audience of Greek theater.
