you would have prefered euthanasia by something quicker? controlled morphine OD? Lethal injection? taken out back and shot?
Actually causing someones death by direct action rather than by withholding life support (including artificial feeding) is considered as a different class of actions legaly and ethically.
Animal people consider injections much more humane than letting the animal wilt away over time. And for some centuries, indeed, shooting a horse was more humane than just letting him gradually die.
Yes, by God, I would prefer it that way, if I HAD to choose how to execute an innocent person.
But the real choice was between letting her die (by neglecting her, no less) and letting her be cared for by her family.
In which the latter is ALWAYS my choice.
