Creon reveals his rigidity and insecurity when he tells his son Haemon "the way to behave: subordinate / Everything else, my son, to your father’s will." Creon demands blind obedience and filial devotion from his son simply because he is Haemon's father. Creon's rigidity will end up costing him his son when Haemon defies him to stand up for Antigone. Creon demonstrates his insecurity as the new king of Thebes when he asks Haemon, "If I permit my own family to rebel, / How shall I earn the world’s obedience?" Creon sounds desperate to firmly control the citizenry and fears that if he allows his niece, Antigone, to openly defy him, his authority will be lost.
Regarding Ismene, Creon tells the chorus, "One has just now lost her mind; the other, / It seems, has never had a mind at all." Here, he means that Ismene has no strength of character or ability to think or speak for herself. It stands to reason, then, that another of Creon's flaws is misogyny. He considers Antigone insane for her defiance, but he also maligns Ismene for her obedience.
