> How much of this is anything beside human nature? Experience. Having seen it before. All the way through. Many times. Yes, an MD fresh out of medical school might react just like anyone else: try to preserve/prolong life of their loved ones at all costs. Once they've worked in the ICU for even a few months? They swear they'd never do that to a loved one. (source: live with a medical resident)
