Reactions to performances of the tragedy have indeed been
strong; during an 1882 performance in Baltimore a soldier on guard duty,
"seeing Othello… about to kill Desdemona, shouted: 'It will never be said
in my presence a confounded Negro has killed a white woman!' whereupon "he
fired his gun and broke an arm of the actor who was playing Othello"
(quoted Bate, 222)" (Pechter 12). John Quincy Adams used words rather than
gunfire in his indictment of the play, stating "The great moral lesson of
the tragedy of Othello is that black and white blood cannot be intermingled in
marriage without a gross outrage upon the law of Nature; and that, in such
violations, Nature will vindicate her laws" (Kaul 10).
A.C Bradley, on the comparisons between Hamlet and Othello: “[Hamlet and Othello share] the fascination of the supernatural, the absence of the spectacle of extreme undeserved suffering, the absence of characters which horrify and repel and yet are destitute of grandeur.”
Carol Thomas Neely writes that Iago, “destroys his superior by destroying Othello’s belief in his own superiority and the bonds which confirm that superiority.”
Carol Thomas Neely ‘Othello and Iago as closely identified with each other; they are "two parts of a single motive--related not as the halves of a sphere, but each implicit in the other.’
