I have heard the sentiment before that ICU doctors would rather die than go through the ICU. Couple this with PTSD being a common side effect from ICU care and it starts to make a picture that maybe death is just the way to go.
It does not surprise me that many would choose to just die ASAP if something bad happened to them.
“You should put your wishes in an advanced directive so you don’t suffer in the ICU in ~hopeless situations” (true) and “there are a non-negligible number of cases where the suffering in the ICU is not worth the modest life extension according the patient’s own values” (also true) and “the balance between life extension and quality of life errs, on average, too much toward the former” (plausibly true) are nothing like “the ICU is worse than death for most people”.
