Dr. Annie McKeown O'Donovan:

I do not think there is anything else. The criteria I have repeatedly spoken about concern somebody who is imminently dying, has exhausted all avenues of available respite, is at the point where his or her current and prospective quality of life are unacceptable and who values death now more than the inevitably short period of life judged by that person as intolerable, which will result in death soon anyway. The value-of-life argument ties back into the question I was asked, namely, whether this intrinsic value changes at this short period of life. No. Of course life is intrinsically valuable and of moral worth.

What happens is that it is outweighed. The want to die outweighs the want to continue living through something that is intolerable and is going to be over soon anyway. It can be overwritten. The other question is how this suffering is categorised ethically. As has been repeated and discussed, it is something that is subjective and should be a discussion between an individual and their healthcare provider.
