The Last Samurai
One of my favorite films. If you disregard the fictitiousness, you will find a story of redemption, beauty, honor, and service.
A man destined to burn out into nothingness after bringing only blight into the world, tormented by regret and self loathing, he is given a second chance, and with it he opens his mind and soul to the purity of a life in service to that which surrounds him in every breath. He finds a way of life he is unworthy of living, and devotes himself to earning it. A way of life that nears it's end. He gives everything he possibly can to keeping it's fire burning, not only because of what it's given him but because of what it can give the world.
"You believe a man can change his destiny?"
"I think a man does what he can, until his destiny is revealed."
