Remember the midwives of Egypt during the slave days of the chosen people? They refused to kill the male babies telling the authorities that the Israelite women delivered without their help before they could arrive. Hence, they avoided becoming cooperators in infant killing.
But that was then and this is now.
The American Nurses Association (ANA) recently amended their statement on Nutrition and Hydration at the End of Life. The amended document approves of assisting patients to kill themselves by starvation and dehydration, even those who are suffering from dementia. Read Nancy Valko's commentary on their decision here.
The language is specifically geared to make their decision sound like it respects the dignity of the patient, as if any preference of a patient is legitimate. But what this does is to endanger nurses who don't want to cooperate in evil, as well as the patients for whom they care.
