What do you think a living will is/does??
First of all (and I know the culture of death has managed to change this), a living will should ONLY be about life support and extraordinary measures; hydration and nutrition are BASIC NECESSITIES, there's nothing extraordinary about them.
Secondly, this monster wants to make murder the default treatment absent a living will.
Originally a living will was to ensure if someone did not want to be on life support or have other measures taken, then a living will was a guideline. Now if you don’t want to be starved/dehydrated it better be in writing- and who knows if that would be honored.
