No one would want to be dependent on others, but what if God wanted you to learn a lesson of humility from disability? Yes, I know: nobody in the USA says such things, but here in Asia (or my patients in Africa, or my American Indian patients) understood that disability was a path that their Creator wanted them to travel.
I think the “Christian” version of this is “take up your cross and follow me”. But of course, few “Christians” in the US would hear such a sermon nowadays. The only one I heard remind his listeners that all religions agreed with Buddha that life is suffering, was Jordan Peterson. Imagine that: an agnostic teaching the lessons that rich pastors don't want to teach.
“...quality of life is a slippery slope. Lots of bioethicists out there have lists on who they think should be killed because they are like the Nazis and see no worth in a life that is crippled, brain damaged, etc. Be afraid, be very afraid...”
It is our duty to plow on to the last breath. Avoiding extraordinary measures is a prerogative but active euthanasia leads right to Doctor Mengele.
