470. What is forbidden by the fifth commandment?

2268-2283

2321-2326

The fifth commandment forbids as gravely contrary to the moral law:

• direct and intentional murder and cooperation in it;

• direct abortion, willed as an end or as means, as well as cooperation in it. Attached to this sin is the penalty of excommunication because, from the moment of his or her conception, the human being must be absolutely respected and protected in his integrity;

• direct euthanasia which consists in putting an end to the life of the handicapped, the sick, or those near death by an act or by the omission of a required action;

• suicide and voluntary cooperation in it, insofar as it is a grave offense against the just love of God, of self, and of neighbor. One’s responsibility may be aggravated by the scandal given; one who is psychologically disturbed or is experiencing grave fear may have diminished responsibility.
