takahmamash:
based on your reasoning, if this elderly woman’s dying wish was to eat pork, you would allow it.
Halachah TRUMPS dying wishes. That why we have a Rov. If your Rov cannot or will not give you a Pska, at least he can send you to a Rov that is more knowledgeable about end of life issues.
But “express wishes” don’t count, the Torah does.
