428. Those who are born with a disposition to mercy, but do not make their natural acts of mercy spiritual, as they would if they did them out of true charity, believe that charity consists in giving to everyone who is poor and helping everyone who is needy, without previously enquiring whether the poor or needy person is good or wicked. For they claim that this is unnecessary, since God has regard only to the help or alms given. But after death these people are easily distinguished and separated from those who have performed the kind acts of charity with prudence. For those who did them from that blind notion of charity, are as kind to the wicked as to the good, and the wicked use these kindnesses to do evil, and so to harm the good. So it is that the people who do kindnesses are to blame too for the harm done to the good. Doing a kindness to an evil-doer is like giving bread to a devil, which he turns into poison. Any bread in the hands of a devil is poison, or if it is not, he turns it into poison, an action accomplished by enticing someone to evil by being kind to him. It is also like offering one's opponent a sword, with which he can kill someone. Or like giving a werewolf a shepherd's staff to lead the sheep to pasture; yet when he has got it he leads the sheep away from the pastures into deserted places and there slaughters them. It is like giving the office of magistrate to a robber, whose only purpose is to keep his eyes open for booty; he dispenses justice and makes his decisions with an eye on how wealthy and affluent his victim is.
