I’m not quite sure what you are saying. It is permissible to remove an embryo which has no chance of survival, but otherwise would result in the death of the mother. Such an event occurs most commonly in a uncommon problem called an “Ectopic pregnancy” (the embryo implants into a Fallopian tube instead of the uterus). There is no hope for the baby, and the mother will die unless the baby is removed.
It is NOT permissible in this conceivable instance to remove an Embryo which has no chance to live.Removal of liver results in instant death to Mother,and Embryo,removal of Embryo only is abortion,removal of fallopian tube doesn’t kill Mother,and is Indirect
The surgical removal of the embryo is permitted because the purpose of the procedure is to save the mother, not to kill the embryo. This is sometimes called the “double effect,” and it is morally permissible. The Church considers intent very seriously. If the intent is to save the mother, and not to kill the embryo.
Removing Embryo from liver would be Direct Abortion,so Embryo would die along with Mother.So a Father with 5 or more children would have to watch his wife die and rear his children himself.If the Embryo had been removed it would have died,thus Direct Abortion,but Mother would have lived and excommunicated.This is where your Catholic Faith would be tested to its limits
There was a million to one case miracle where the Embryo landed on the Mother’s liver and was born perfect and healthy.Mother never even knew she was pregnant
The same is true of painkillers in medical environments. Painkillers make us more comfortable, but reduce our cardiac and pulmonary (and digestive) capacity. Administering painkillers to terminal patients may hasten their deaths, but the painkillers were not prescribed for that purpose, but were prescribed for a morally acceptable cause (to alleviate pain and suffering). It is morally permissible to administer such painkillers to terminally ill patients if the primary purpose is to alleviate pain (an act of charity) and not to kill the patient (a misguided act of charity).
If the doctor perscribed painkillers to provide relief from pain and suffering, then the action is morally permissible, even if the doctor is “pretty sure” that the painkiller would result in the death of a patient, and that he knew of no other (less fatal) way to alleviate this suffering.
