As I mentioned, in the vast majority of cases and even in the most severe situations, something can be done to attempt to ameliorate. Failing all of that, it is conceivable that there could be an illness that's irremediable. Honestly, that would have to be assessed on a case-by-case basis. We're suggesting that the thinking process behind the patient making this request needs to be teased apart very carefully, because while they have a perception of something being irremediable, it may not actually be irremediable.
