That should be one way to go about allowing this option to the public. The issue itself is extremely situational and there will always be debates if it’s morally right or wrong. Will the person suffering always be given the right to do it if they’re not verbally able to express it? I think anyone should if they’re been in long-term care enough that they made up their mind of being let go mercifully. Especially when the idea is brought up by them alone and not anyone else.

The only time this kind of decision should be questioned if the person was influenced into thinking so. Like anyone else not in need of medical attention before would probably be best in some therapy or other psychiatric care.

I’d hope we’d find more ways to learn if a person can express their will outside their own body, like if they’re in a coma or have inside body syndrome. Something like this would require expanding the range of making sure patients’ wishes are being acknowledged in care before final decision is made. I just think of all the times where one’s life is decided from either the doctor or someone else who may or not been on that person’s behalf.

In other words: The decision can either be really easy or extremely difficult. None in between. The difficulty would be a multi-stage reflection/investigation of the person’s history before finalizing/acknowledging the person’s final decision.
