Throughout the play there is much deceiving from Iago. One example is how Iago tries to use Cassio to enrage Othello. "I humbly thank you for 't. I never knew a Florentine more kind and honest."(pg 113) This is a perfect example because really he is rarely honest, but he is deceiving Cassio and making him think that he is just trying to help.
Iago has also caused Cassio to become inebriated at the party even though he originally did not want to drink. "Not tonight, good Iago. I have very poor and unhappy brains for drinking. I could well wish courtesy would invent some other custom of entertainment."(pg 83) But very shortly after he tricks him to drink more, causing him to stab Montano. There is much deceit throughout the play and these are good examples.
