What are Haimon's arguments that he presents to tell Creon he's making a mistake about his judgment of Antigone?

The dialogue between Haemon and Creon reveals Creon's strengths and flaws as a leader. His main strength is that he is concerned with justice and fairness. In his reaction to Haemon, he emphasizes that the good and just ruler should not favor his own family but apply justice impartially to all people.

The main weaknesses Creon reveals about his own character are authoritarianism and too high an opinion of his own rectitude. He reacts to Haemon's criticism not by listening carefully to what Haemon is saying but by emphasizing how the father must have authority over the son and the ruler over his subjects.
