We shall reflect that he already bears, or will bear, the whole penalty of his error; if he spoils his life by mismanagement, we shall not, for that reason, desire to spoil it still further: instead of wishing to punish him, we shall rather endeavor to alleviate his punishment, by showing him how he may avoid or cure the evils his conduct tends to bring upon him. He may be to us an object of pity, perhaps of dislike, but not of anger or resentment; we shall not treat him like an enemy of society: the worst we shall think ourselves justified in doing is leaving him to himself, If we do not interfere benevolently by showing interest or concern for him.
