Had he not had a greater purpose, the saving not of his…

““Had he not had a greater purpose, the saving not of his life but of his soul, the resolve to become a good and honourable man and upright man as the bishop required him - had not that been his true a deepest intention? Now he talked of closing the door on the past when, God help him, he would be reopening the door by committing an infamous act, not merely that of a thief but of the most odious of thieves. He would be robbing a man of his life, his peace, his place in the sun, morally murdering him by condemning him to the living death that is called a convict prison. But if, on the other hand, he saved the man by repairing the blunder, by proclaiming himself Jean Valjean the felon, this would be to achieve his own true resurrection and firmly close the door on the hell from which he sought to escape. To return to it in appearance would be to escape from it in reality. This was what he must do, and without it he would have accomplished nothing, his life would be wasted, his repentance meaningless, and there would be nothing left for him to say except, 'Who cares?' He felt the presence of the bishop, more urgent than in life; he felt the old priest's eyes upon him and knew that henceforth Monsieur Madeleine the mayor, with all his virtues, would seem to him abominable, whereas Jean Valjean the felon would be admirable and pure. Other men would see the mask, but the bishop would see the face; others would see the life, but he would see his soul. So there was nothing for it but to go to Arras and rescue the false Jean Valjean by proclaiming the true one. The most heartrending of sacrifices, the most poignant of victories, the ultimate, irretrievable step - but it had to be done. It was his most melancholy destiny that he could achieve sanctity in the eyes of God only by returning to degradation in the eyes of men.””
