(b) Joy about things that are sinful or consequent on sin rejoices, not that what was done was wicked, but over other circumstances that were good or indifferent. Examples: An employer admires in the conduct of a dishonest employee, not the injustice committed, but the shrewd manner in which the fraud was perpetrated. A bystander is very much amused to witness a fight, not because he likes discord, but because the acts and remarks of the fighters are comical. A man rejoices when he hears that a friend has committed suicide and made him his heir, if the joy is confined to the second part of the news. 238. The moral gravity and species of evil rejoicing has the same character as the past sins that are its object (see 70 sqq.). For to rejoice over sin is to approve of it, and therefore to be guilty of it in will. Example: A prisoner who, to overcome melancholy, thinks over the times he became intoxicated in the past, is guilty again of those sins, with their number and circumstances adverted to. 239. What has been said about evil rejoicing applies likewise: (a) to boasting over sin committed, because this implies complacency in the sin; (b) to sorrow over sin omitted, because this means that one approves of sin rather than virtue. 240. To be sorry because one performed good that was not obligatory is not sinful of itself, but it may become so by reason of the evil motive of the sorrow, or of the danger of sin. Examples: If a person is sorry that he performed many unnecessary devotional exercises, because he injured his health thereby, his sorrow is not sinful. If he grieves over this because he now dislikes religion, his sorrow is made bad by his evil motive. If he regrets that he married, this is sinful if it leads him to neglect the duties of his state and commit injustice. 241. Evil desires are acts of the will by which one deliberately intends to commit sin in the future. They are of two kinds, viz., absolute and conditional: (a) absolute or efficacious desires are those in which the mind is fully made up to carry out the evil design, come what may; (b) conditional or inefficacious desires are those in which the purpose to commit sin hinges upon the fulfillment of some event or circumstance that is explicitly or implicitly willed. 242. Absolute evil desires have the same moral gravity and species as that to which they tend (i.e., they take their character from the object, end and circumstances). Example: He who plans to steal a large sum from a benefactor in order to be able to live in idleness and dissipation, sins gravely against justice, and is also guilty of ingratitude and intemperance, for he has committed all these sins in his heart.
