Sinfulness of Cooperation

The Sinfulness of Cooperation.—The Sinfulness of Formal Cooperation.—(a) Formal cooperation is always sinful, for it includes the approval of the sin of another and the willing participation in the guilt of that sin.

(b) Formal cooperation is from its nature opposed to charity; for charity disapproves of the sins of others and strives to prevent them, while formal cooperation, on the contrary, approves and assists the sins of others.

(c) Formal cooperation is also opposed to the virtue violated by the sin of the principal agent, in so far as the will of the cooperator delights in or approves of the circumstance of help given to the sin of the other (see 1468). Thus, if one opens the door to a caller whom one suspects to be a burglar and at the same time mentally sympathizes with the act of burglary, one is guilty in will of the act one approves.

(d) Formal cooperation as to its external act is opposed to the virtue violated by the cooperator, when the external act has a malice of its own. Thus, if one swears falsely in order to conceal the presence of a burglar hidden in the house, one is guilty of perjury; if one disobeys the laws of the Church by marrying clandestinely, one is guilty of disobedience; if one scandalizes third parties by cooperating with sin, one is guilty of scandal; if one shares in fraud, one is guilty of injustice, etc. Hence, in confession it does not suffice to say that one has cooperated in sin, but one must also tell the sin committed and the necessary circumstances.

The Sinfulness of Material Cooperation.—(a) Material cooperation, in itself, is sinful; for charity commands that one strive to prevent the sin of another, and much more therefore does it forbid one to help in the sin of another. (b) Material cooperation, in case of great necessity, is not sinful; for charity does not oblige under serious inconvenience to self, and it does not forbid one to cooperate by an indifferent act to prevent a neighbor from committing a greater evil than the evil he has in mind. He who cooperates materially through necessity does not cause sin, but uses his own right, which the bad will of the other abuses and makes an occasion of sin (see 1447 d).
