In William Shakespeare's play "Othello", we learn about the dramatic contribution of the antagonistic character Iago, who through his manipulative and hypocritical qualities satisfied his insatiable desire for revenge, and showed his constant deception of the entire cast. Iago is incredibly manipulative. He seems to be aware of how those around him will act and react to certain events.

On the surface, Iago appears to be someone completely different. When speaking to Othello he says, "My lord you know I love you" (III.iii.116), but to Roderigo a whole other side is revealed through the words, "In following him, I follow but myself./Heaven is my judge, not I…
