Shakespeare got nearer to what we may term the domestic as opposed to the political criminal when he created Iago. In their envy and dislike of their fellowmen, their contempt for humanity in general, their callousness to the ordinary sympathies of human nature, Robert Butler, Lacenaire, Ruloff are witnesses to the poet's fidelity to criminal character in his drawing of the Ancient. But there is a weakness in the character of Iago regarded as a purely instinctive and malignant criminal; indeed it is a weakness in the consistency of the play. On two occasions Iago states explicitly that Othello is more than suspected of having committed adultery with his wife, Emilia, and that therefore he has a strong and justifiable motive for being revenged on the Moor. The thought of it he describes as "gnawing his inwards." Emilia's conversation with Desdemona in the last act lends some colour to the correctness of Iago's belief. If this belief be well-founded it must greatly modify his character as a purely wanton and mischievous criminal, a supreme villain, and lower correspondingly the character of Othello as an honourable and high-minded man. If it be a morbid suspicion, having no ground in fact, a mental obsession, then Iago becomes abnormal and consequently more or less irresponsible. But this suggestion of Emilia's faithlessness made in the early part of the play is never followed up by the dramatist, and the spectator is left in complete uncertainty as to whether there be any truth or not in Iago's suspicion. If Othello has played his Ancient false, that is an extenuating circumstance in the otherwise extraordinary guilt of Iago, and would no doubt be accorded to him as such, were he on trial before a French jury.
