Is Willy Loman misguidedmalicious or mistaken?

Answer 1

From Shmoop Literature on Death of A Salesman

http://www.shmoop.com/character/literature/arthur-miller/death-of-a-salesman/willy-loman.html

Willy is a rather insecure guy. He tries to make himself feel better by lying to himself and his family. In his world of delusion, Willy is a hugely successful salesman. He disguises his profound anxiety and self-doubt with extreme arrogance. Periodically unable to maintain this image of strength, Willy despairs and pleads with successful people around him for guidance and support. Despite his efforts, it becomes clear that Willy Loman is not popular, well liked, or even good at his job. In fact, he was never was. In all likelihood, he never will be. Now an older man, Willy can no longer drive competently, pay his bills, or sell anything.

Willy is a tragic character because he never grows.
