The "prime directive" of medicine is simple and to the point.

"First, do no harm."

In medicine, we are not tasked with the impossible job of deciding whether or not a person deserves to live or die. I have treated cops & prisoners. Priests & atheists. Rich & poor. It is what a doctor is supposed to do, and we are not supposed to do less for a patient based on our judgment (or even society's) of how they lived their life.

Some will say, with some justification, that we do practice some indirect judgment by accepting or not accepting Medicaid patients, the indigent, etc. That is true, and I am shamed by my colleagues who turn patients away based on ability to pay.
