Context

But no man has the right to set himself up as a purely moral judge and requiter, and punish the misdeeds of another with pains which he inflicts upon him, and so to impose penance upon him for his sins. Nay, this would rather be the most presumptuous arrogance; and therefore the Bible says, “Vengeance is mine; I will repay, saith the Lord.” But man has the right to care for the safety of society; and this can only be done by interdicting all actions which are denoted by the word” source
