How is Othello a noble man who is simply deceived into believing a lie?
The other teams argument is "Othello is an inherently insecure character prone to violence. Iago simply takes advantage of his already flawed and corrupt nature. I NEED ARGUMENTS FOR MINE AND REBUTTLES FOR THE OTHER TEAM. PLEAAASE HELP!
The key scene to explore is Act 3 Scene 3 - as well as Iago's statements about himself at the start of the play. We learn that Iago is deliberately seeking to destroy Othello and therefore creates and manipulates situations to allow him to do so. This reveals to the audience the evil nature of Iago. This evil nature is also revealed through Iago's actions to Roderigo and Cassio, as well as his killing of Emilia at the end of the play.
Othello, although insecure at times, faces a psychological onslaught in Act 3 Scene 3.
In addition, if Iago is able to act only due to the flawed and corrupt nature of Othello, how does that explain Iago's ability to dupe the other characters? The suggestion is that Iago is a plausible but totally evil character who can manipulate any weakness he sees in others for his own end.
