Considering the Aristotelian definition of a tragic hero, Othello's suicide is significant because it marks the protagonist's acceptance of responsibility for his actions and serves as his self-punishment. Some critics argue that in taking his own life, Othello actually takes the easy way out. (He explains, after he stabs Iago and Iago brags that he won't die as a result of the wound, that in his view "'tis happiness to die.") Essentially, these critics think that Othello doesn't have to suffer the consequences of his actions for very long. Other critics, though, argue that Othello's suicide is the ultimate punishment. If we consider suicide to be a sin, which was the accepted belief during Shakespeare's time, then we can assume that Othello will end up in hell for what he has done. Either way, Othello's suicide is his form of self-punishment and shows that he has accepted responsibility for his actions.
