Nevertheless Iago seem to be much smarter than Stanley in comparison.

We immediately see Iago as representative of the very basest elements of humanity.

Iago is a devious man, a liar, a manipulator, and a psychopath.

Othello is a classic example of Shakespeare’s play where good fights against evil, where the action ends with the triumph of universal human values. That’s why the touched theme of racism in Othello witnesses about profound humanism of William Shakespeare. English society of Elisabeth I had an image of black people only as of slaves; the portrait of an educated and nobleman of African heritage was something ridiculous. Shakespeare, in fact, described Othello in a manner which made him the most decent and noble character of the tragedy: as he represented good morality and loyalty, while Iago a white man is described as the most vicious and mean person. Shakespeare described Othello as a personality and hero who didn’t even think about realizing his ambitions through dirty and immoral schemes. Iago visa versa sees betrayal as the only mean to achieve his purpose and to revenge.

Iago even persuades Roderigo to kill Cassio with his lies about Cassio and Desdemona’s affair.

I feel as though we have our fair share of Iago’s in today’s society.

Desdemona, the heroine from the tragedy is Othello is a different person. She is the apparent embodiment of woman of Medieval Italy: calm, submitted to husband, dependent and faithful. She lacks such qualities as the reason, independent thinking, and willpower. In her behavior, Desdemona is very similar to Antigone’s sister Ismene, who is very beautiful but who at the same time lacks independence and willpower. As a result of her naïve behavior and trustfulness, she becomes a victim of Iago’s manipulations and dies. Her too friendly relations with Casio would be suspicious anyway as it wasn’t a natural behavior for a married woman to spend time with other men, and she had to consider it, but instead, she thought it could take place. We can also outline that her decision to marry Othello may be regarded as the demonstration of courage and devotedness to a beloved person, but at the same time considered as the demonstration of levity. Even though that she took this decision and tried to convince her father of her free will:

It is obvious that Othello is a much 'deeper', more sensitive man than Iago.

Here Othello is praising Iago for being such an honest man and for knowing the human mind.
My lord, you know I love you.
My lord, you know I’m your friend
I think thou dost.
And for I know thou 'rt full of love and honesty
And weigh’st thy words before thou giv’st them breath, Act 3 Scene 3.

Another contrast is that Iago's motivation is himself and his self-interest.

No other character can even come close to his evil (Iago: The 1).

Roderigo turns off to Othello; and here comes one, if not the only, seeming justification of our blackamoor or negro Othello. Even if we supposed this an uninterrupted tradition of the theatre, and that Shakspeare himself, from want of scenes, and the experience that nothing could be made too marked for the senses of his audience, had practically sanctioned it,—would this prove aught concerning his own intention as a poet for all ages? Can we imagine him so utterly ignorant as to make a barbarous negro plead royal birth,—at a time, too, when negroes were not known except as slaves?—As for Iago's language to Brabantio, it implies merely that Othello was a Moor, that is, black. Though I think the rivalry of Roderigo sufficient to account for his wilful confusion of Moor and Negro,—yet, even if compelled to give this up, I should think it only adapted for the acting of the day, and should complain of an enormity built on a single word, in direct contradiction to Iago's 'Barbary horse.' Besides, if we could in good earnest believe Shakspeare ignorant of the distinction, still why should we adopt one disagreeable possibility instead of a ten times greater and more pleasing probability? It is a common error to mistake the epithets applied by the dramatis personae to each other, as truly descriptive of what the audience ought to see or know. No doubt Desdemona saw Othello's visage in his mind; yet, as we are constituted, and most surely as an English audience was disposed in the beginning of the seventeenth century, it would be something monstrous to conceive this beautiful Venetian girl falling in love with a veritable negro.

Iago, in the play Othello, is a very intriguing villain....

Roderigo remarks, "That thou, Iago, who hast had my purse as if the strings were thine." [Act I, Scene I, Line 2] Throughout the play, Iago leads Roderigo, professing that ".

Roderigo/Roger and Iago/Hugo plot to kill Michael(Cassio).

Othello and Desdemona, of course, knew what consequences would their marriage have, but none of them was ready. As a result instead of doing the best to save the union, mutual trusts and love both of them started to alienated one from another after the marriage on the island of Cyprus. Desdemona appears at the beginning of the play a very independent and mature lady who can defend her love and her marriage, but her independence ruins after her marriage as she turns into a submitted wife of a jealous husband. Her inability to prove innocence and her inability to avoid the situation which took place with Casio and which was exaggerated and played over by Iago led to her tragic end. It becomes evident at the end of the play that Desdemona was ready for her murder, and she didn’t want to protest against it:
