The power to use another person and manipulate them is a great skill which Iago possess, but without all of Othello ‘s weakness’, it would be a pointless skill, which is why the main cause of Othello’s tragedies is his weaknesses. His passion to follow his will, not his mind, means he is easily susceptible to jealously which, for Desdemona, means her untimely death. The fact that Othello is an outsider makes him vulnerable to questioning how well he knows the customs and traditions of the foreign land he is in. However Iago’s malice is the key to Othello’s downfall; without him taunting Othello into near madness, Othello would never have destroyed his own life. This is why Othello’s weakness is as much a cause of his downfall as Iago’s Malice.
Othello’s passion, or even ego, make him easily manipulated and thus can be exploited into making him jealous. Othello’s great and passionate love for Desdemona is seen clearly as he recalls his tale of wooing her to the court remembering how she was seduced by his tails of danger and he “lov’d her that she did pity them”. This passion is what Iago uses to seek his revenge on Othello for not choosing him as his lieutenant. For this love might be seen as a good passion but when twisted by Iago this love is what burns Othello on the inside. Iago makes it seem as if Desdemona had given Othello’s handkerchief to Cassio. Because of this Othello becomes apprehensive to the fact that he has been “cuckold” by none other than Cassio, and this jealousy bring out the “green-eyed monster” in him to act on this enraged jealousy. As he is passionate, he acts without thought and these blind actions lead him to murder his wife without seeing reason. In his anger when he is torn between his love for Desdemona and his rage for being “cuckold” he lashes out at iago who fills his “mind with poison” yet again and this is the final straw before he murders
