As a doctor, I think we are prepared for our own death (not so much for illness though). Especially during the last days or months we know exactly what's happening. I agree that the less-care-but-less-side-effects way is chosen much more often by doctors for themselves and their close relatives (I personally administered to my mother opioid to accelerate death due to terminal cancer a couple of days before the expected end that would be tortuous).

For my end stage patients I advise full palliative analgesic and sedative therapy but usually against futile chemos and intubations. There is a discussion where ICU doctors and oncologists have to take part.
