It is true that, once embarked on his course, Iago could not turn back, even if this passion did abate; and it is also true that he is compelled, by his success in convincing Othello, to advance to conclusions of which at the outset he did not dream. He is thus caught in his own web, and could not liberate himself if he would. But, in fact, he never shows a trace of wishing to do so, not a trace of hesitation, of looking back, or of fear, any more than of remorse; there is no ebb in the tide. As the crisis approaches there passes through his mind a fleeting doubt whether the deaths of Cassio and Roderigo are indispensable; but that uncertainty, which does not concern the main issue, is dismissed, and he goes forward with undiminished zest. Not even in his sleep—as in Richard’s before his final battle—does any rebellion of outraged conscience or pity, or any foreboding of despair, force itself into clear consciousness. His fate—which is himself—has completely mastered him: so that, in the later scenes, where the improbability of the entire success of a design built on so many different falsehoods forces itself on the reader, Iago appears for moments not as a consummate schemer, but as a man absolutely infatuated and delivered over to certain destruction.
