In Arthur Miller's Death of a Salesman, Willy is the tragic protagonist who ultimately brings on his own demise. Throughout the entire play Willy is disillusioned into thinking that he is important and successful. He also believes that true success is accidental and not based on hard work and dedication. Because of this, at the end of the play, Willy commits suicide in order to get insurance money for his son Biff's business. Tragically, Willy's decision was foolish because insurance companies don't cover suicides.
