When Iago finds out that Othello, the man he had served for a long time, had named someone else for the position he wanted. Iago says “Forsooth, a great arithmetician, /One Michael Cassio a Florentine,” (I, i, 20-21) Othello believes that Cassio is a good fit for the position of a lieutenant. Iago thinks that this new lieutenant knows more about the numbers than how to fight in a battle. He is good at math and possibly how to create strategies in battle but he can’t possibly be able to fight.

Finally he destroys Cassio’s life by (not permantatly) handicapping him and striping him of his title as lueitenent, all so that he could live a happy live without people that he didn’t like around him, with lots of money and the title that he wants. Iago shows the fact that individuals will react in mean and horrible ways to be
