Shakespeare's "Othello" describes a cruel chain of events ending in tragedy. This is one argument for and destruction caused by envy and malice of a man whose actions on behalf of revenge against a firm friend out of control, and go beyond reprisal, the conclusion is the loss of life through murder and suicide. Iago's activities appear to be guided by a combination of emotions normally resentment, greed and jealousy directed primarily towards Othello and indirectly another character. The following attempts to examine the possible reasons behind Iago's disposition of hatred. The main reason for the anger of Othello Iago is that professional jealousy, Iago's failure to obtain the position of Lieutenant of Othello's army, which has given to Michael Cassio, "a great arithmetic 1, 1, and a scholar that "the big three of the city" 1, 1 such as, he is recommending that the lieutenant is his "preference goes by letter and affection" 1, 1, the doing this Othello ignores the established chain of command where by "each second stood heir ro or" first "1, 1. Disregard grading Othello" old "1, 1 greatly offends Iago, he being the former lieutenant is his position that more than Cassio.

This feeling of resentment is deeply compounded since he believes it deserves more than a man who has "never set a squadron in the field, or the division of a battle knows" 1, 1. whom "his eyes had seen the proof" 1, 1, which is in the experience of war. Yago he has confidence in their own abilities in warfare (the peach in Act 1 seen a show this "I know my price, I better not worse a place") all of which are practically useless.
