Interesting.
A cheeseburger, fries and a shake are food and drink when we feed ourselves or cut them up into little bites and use a spoon to feed our children. They don’t miraculously become something other than a cheeseburger, fries and a shake just because we use some other method to deliver them. Food and water are always basic human rights, always ordinary care, and always mandatory in Christian medical ethics unless the body cannot assimilate them.
If they are going to be stopped, the question must be asked: “What is the proximate cause of death?”
In this case, will Casey die from the dementia or the sepsis, or will he die from dehydration leading to blood volume loss and organ failure?
If the latter them he will die from euthanasia, not from the withdrawal of “life support.”
