218. When the objects are morally one, they may become many through the intention of the one who acts. Example: He who calumniates a family of three persons by saying they are all dishonest, commits three sins, if he intends three distinct injuries (e.g., against the business of one, the religious reputation of another, and the friendship of the third). So also he who steals part of the money in a purse, and later on, having another opportunity, decides to steal the rest, commits two sins.
219. When the objects are not morally one in themselves and cannot be apprehended as such, distinct sins are committed. Example: He who intends to miss Mass all year, foresees at least in a confused way many distinct violations of the law; he who purposes to rob various proprietors foresees at least in a vague way many separate and complete external acts of robbery.
220. Comparison of Sins.—Sins that differ in species differ also in gravity, those being more serious that depart further from the norms of reason and the law of God.
221. Other things being equal, those sins are worse that offend against a more noble object or a more noble virtue. Hence, sins that are directly against God (such as infidelity, despair, and hatred of God) are the most serious of all; while sins against human personality (such as murder) are more serious than those against human rights (such as theft).
222. Of those sins that are opposed to the same virtue, that one is worse which is opposed to the principal inclination of the virtue. Thus, avarice is more foreign to the virtue of liberality than the opposite vice of prodigality; timidity is more contrary to bravery than its opposite rashness.
223. The gravity of a sin is increased in the following ways:
(a) by the circumstances, in so far as they give it a new species of malice (e.g., theft from a church) or increase its malice within the species (e.g., money given prodigally and to those who do not deserve it, or money stolen in a large quantity);
(b) by the greater willingness with which the sin is committed. Hence, those who sin through ignorance or under the excitement of passion are less guilty than those who sin in cold blood;
(c) by the condition of the person offended. Thus, a sin is made worse according as the person offended is nearer to God by reason of his personal holiness or the sacredness of his state or the dignity of his office, or is nearer to the offender himself. Hence, an injury is greater if done to a priest, a public official or one’s own family, than if done to another who has not the same claim to honor or justice;
(d) by the condition of the person who sins. Those who are better instructed or otherwise better advantaged, or who are supposed to give good example to others, sin more grievously by reason of their greater ingratitude and of the greater scandal they give, whenever they sin deliberately;
