Although the reasons why William Shakespeare created a sinister character like Iago are unknown, it can be seen as a commentary on the inexplicable evil that exists in the world and how good men and innocent people can fall victim to it. In Othello, Shakespeare creates a psychopathic character named Iago who visits the extremes of human depravity, fueled by sordid emotions while adhering to no morality, and who commits reprehensible and inscrutable actions often with little or no reason other than his own pleasure in manipulating innocent and blind. vendetta.

Get an original essay Roderigo, after Othello's marriage to Desdemona, is blinded by the jealousy that Iago exerts to manipulate him by promising him his chance with Desdemona; however, it is quickly apparent that Iago, in reality, has no concern for Roderigo and instead only uses him for his own purpose and pleasure, showing how psychopaths manipulate everyone they meet. Although it appears that Iago has developed a friendship with Roderigo for shared reasons of revenge against the Moor, this feeling is quickly dismissed by Iago who ridicules him behind his back and amuses himself as if he "would spend his time with such a snipe, / if he were not for my sport and profit” (1.3.376-377), highlighting early in the play what kind of man Iago is before the audience fully sees the extent of Iago's deception Roderigo, Iago is able to exploit him as a pawn solely for his revenge against Othello and in the meantime to line his own pockets. Later in the play, Roderigo gets a sense of Iago's manipulation and goes to confront him, only for Iago to influence him again. once exploiting his weakness, promising "If next night you will not have fun with Desde-/ mona, take me from this world with treachery and/ Invent engines for my life" (4.2.215-217), once again, exploiting Roderigo's blind lack of Desdemona, this time going so far as to convince Roderigo to kill Cassio by "blowing out his brains" (4.2.230) to prevent Othello and Desdemona from leaving Cyprus. With this action Roderigo preserves his opportunity and Desdemona; furthermore, Iago keeps his promise to kill Cassio, but does so through a prosecutor who would get all the blame so as not to arouse suspicion, showing how Iago considered Roderigo a superfluous tool for his punishment and how quickly Iago was ready to get rid of him . . The same relationship of feigned interest and eventual betrayal parallels that between Iago and Cassio, establishing that Iago has no true allegiance except to himself. Although Iago seems incapable of feeling real emotions, his jealousy is what drove him to destroy Cassio's life by exploiting his weakness, out of the belief that he was more deserving of the title of lieutenant rather than Cassio, to whom the title went instead, following the Shakespearean theme of jealousy, demonstrating that not only does Iago exploit the jealousy of others, but he himself is dictated by it. He first shows his jealousy of Cassius when he speaks of his military career as "Mere talk without practice, / It's all his trade as a soldier" (1.1.23-24), saying he doesn't deserve the title of lieutenant due to the fact that Cassio has never been a military leader before, unlike Iago who has been in charge of a multitude of deployments and is therefore an obviously better choice for the rank. Although his jealousy played a major role in his intention to undermine Cassio, given his apathetic and devious behavior pattern, it is almost certain that Iago would have ruined Cassio's life..
