Thus an act or omission which, of itself or by intention, causes death in order to eliminate suffering constitutes a murder gravely contrary to the dignity of the human person and to the respect due to the living God, his Creator. The error of judgement into which one can fall in good faith does not change the nature of this murderous act, which must always be forbidden and excluded. The decisions should be made by the patient if he is competent and able or, if not, by those legally entitled to act for the patient, whose reasonable will and legitimate interests must always be respected. Even if death is thought imminent, the ordinary care owed to a sick person cannot be legitimately interrupted. The use of painkillers to alleviate the sufferings of the dying, even at the risk of shortening their days, can be morally in conformity with human dignity if death is not willed as either an end or a means, but only foreseen and tolerated as inevitable.
Palliative care is a special form of disinterested charity.
As such it should be encouraged. CDF, Instruction Donum vitae , intro. Cf CDF , Donum vitae I,1. CIC , can. CIC , can.
