The takeaway from this passage is that Iago is filled with hatred towards Cassio which is important because this contributes to the larger theme of revenge. This is seen in multiple instances in the book where Iago wants to sabotage both Cassio and Othello through a spindle of lies and vague assumptions. Iago as a character connects to a more modern character named Maleficent, who is the villain in the story Sleeping Beauty. Both characters uses their evil powers to acquire satisfaction over those they resent. However, Shakespeare was able to create one of the most villainous characters in literature not through the use of spiritual/physical powers such as what Maleficent has, but through the power of manipulation, deception, smarts and betrayal.
