I have had several students in my classes compare Macbeth to Creon from Antigone by Sophocles. In Antigone, Creon has recently become king, and he wants to gain the respect of the people. He assumes that upholding the law will cause his people to love him, so when he is presented with Antigone's unique situation, he does not care to entertain her side of the story and orders that she be executed. Even though the people side with Antigone, Creon is stubborn and ambitious--just like Macbeth--and will not bend to common logic. In the end, Creon loses his closest family members as a result of his stubborn pride. So, Creon is much like Macbeth in that he follows his own ambition without listening to others around him.
