Othello

Othello's lack of self-knowledge makes him easy prey for Iago. Once Iago inflames Othello's jealousy and sets the darker aspects of Othello's nature in motion, there is nothing Othello can do to stop it, since he cannot even admit that he has these darker traits. Even after he has murdered his wife, and has learned that Iago set a trap for him, Othello is unable to acknowledge the character flaws that were manipulated. He asserts he is "honorable" even in murder. This theme is related to pride, as Othello's pride blinds him to his weaknesses, precipitating his downfall.
