CO-OPERATION IN EVIL

Definition

The concurrence with another in a sinful action. This concurrence may be done in several ways: by acting with another in the same sin, as when a person joins another in perpetrating a robbery; by supplying a person what is helpful in performing a sinful action, such as providing a gun or other deadly weapon; and by commanding or suggesting that one do something sinful, by encouraging him or her or suggesting means of carrying it into effect.
