Shakespeare's Othello, Acts One, Two, Three

I have read Othello a few times before since it is my favorite Shakespeare play. This time while reading Othello Acts one, two, and three I could only think of one thing and thats Jigsaw, or John Kramer, from "Saw". My reason for this weird comparison is that both Iago and Jigsaw use manipulation or games to make others do what they want. They then watch the chaos unfold and see if it ends in their favor. Iago and Jigsaw have no sense of consequences for their actions, they just think of how great it would be it they pulled it off. Then when they are successful in one action, they immediately want to take another risk witch another action. They are like gambling addicts.
