? Pride, envy and greed are all deadly sins. These deadly sins are shown in the play "Death of a Salesman" and "Macbeth", unless these sins are controlled, they can bring you to your tragic downfall. In the play Death of a Salesman "The play's protagonist, Willy Loman, is a man whose perspective is clouded by pride that he would rather maintain the false appearance of success than accept repeated offers of help from his neighbour" (vit wagner, article). Willy Lowman is not popular and he is no longer attractive. He is incapable of doing a good job at selling, but he is unwilling to admit his failure.
