"He did not know that the new life would not be given him for nothing, that he would have to pay dearly for it, that it would cost him great striving, great suffering.

But that is the beginning of a new story -- the story of the gradual renewal of a man, the story of his gradual regeneration, of his passing from one world into another, of his initiation into a new unknown life. That might be the subject of a new story, but our present story is ended."

Nobody is irredeemable.  Hard work, time, and true repentance can make up for any sin committed in this life.
