Tolkien wrote that Boromir was, at his core, a noble man whose moment of weakness came not from evil in his heart but from the Ring’s corrupting power. His fall was brief; he realized his failure at once and died in redemption, defending Merry and Pippin with courage and honor. Tolkien explained that Boromir’s death was meant to show both the weakness of Men before power and their capacity for repentance and noble self sacrifice. Aragorn’s final moment with him hearing his confession and accepting his honor. Becomes the point where Aragorn truly steps into leadership. Boromir’s death pushes him to claim Gondor’s future and fulfill his destiny.
The Lord of the Rings and Game of Thrones star Sean Bean has named Boromir's death scene as the greatest death scene in his entire acting career. This is high praise, considering he has died on screen more than 20 times. "It was just so heroic and tragic."
