Every one who has studied the subject at all is only too well aware that the world offsets the readiness with which it condones a crime for which a man escapes punishment, by its unforgiving relentlessness to the often far less guilty man who is punished, and who therefore has made his atonement.

Context

“Certain crimes of revolting baseness and cruelty were never forgiven. But in the case of ordinary offenses, the man who had served his term and who then tried to make good was given a fair chance; and of course this was equally true of the women. Every one who has studied the subject at all is only too well aware that the world offsets the readiness with which it condones a crime for which a man escapes punishment, by its unforgiving relentlessness to the often far less guilty man who is punished, and who therefore has made his atonement. On the frontier, if the man honestly tried to behave himself there was generally a disposition to give him fair play and a decent show. Several of the men I knew and whom I particularly liked came in this class.” source
