An honourable murderer, if you will;
For nought I did in hate, but all in honour.

– William Shakespeare

Othello, Act 5, Scene 2. Othello justifies himself and his killing of Desdemona by calling himself an honorable murderer. He believes that since he did nothing out of hate but out of a sense of honor, he is not really guilty of a terrible crime. Othello is trying to salvage what is left of his reputation.
