What morals does Othello have?

Answer 1

Othello is a person of high moral standards. He does not run when apprehended by Brabantio and his group, nor does he fight. He is prepared to justify his actions in marrying Desdemona before the court and he does so. Even though he is newly married, his sense of duty tells him that he must go to fight the Turks. When faced with one of his officers who disgraces himself, he demotes him even though he is a close personal friend. Doing what is right is more important than taking care of his friend Cassio.
But all this gets turned on its head when Iago finds his weak spot (which is oddly enough one of his many virtues, his humility) and twists the knife. In the upside-down world created by the fiction of Desdemona's supposed infidelity, Othello tries to act morally, and finds moral justification for his action. What Desdemona is doing is wrong, she needs to be eliminated not only to protect Othello but also to protect others, the most appropriate punishment would be to strangle her in the bed she has defiled--in this way Othello (with help from Iago) finds moral justification for his action. And when the upside-down world collapses around him and he sees Desdemona for what she really was and his actions for the crimes they were, he does not shrink. He asks for understanding, "nothing extenuate", that is, not as an excuse, because he knows the remedy for his crime, and he administers it himself.
