Dramatic significance of the last scene

Willy Loman's suicide can be interpreted as a noble sacrifice, driven by the belief that Biff may go into business with the insurance money he gained from his death. Paradoxically, Willy's suicide may be related to his reconciliation with his elder son; having realized how much Biff cares for him and convinced that Biff does not behave out of spite, Willy can now sacrifice himself for his son.
