There are pros and cons.

Pro (a bit cynical, perhaps): the person doesn't cost the NHS more than the injection. It frees up a bed, and they are short of them. Plus organ donation? For me, when I clock out, in the unlikely event I have anything useful by then, I say let it be used.

Con: if this option had been available years ago, we might not have had Stephen Hawking. He lasted years longer than predicted. I fondly remember him in ST: TNG, "Descent part 1", getting the better of Data, Newton and Einstein on the holodeck.

Pro: the person is relieved of suffering. I don't think they should suffer longer than they have to. Isn't it more civilised to let them choose?

Con: what if the person's in a coma and/or unfit to decide?

I honestly don't know. I do think the right to live as long as you want to includes the right to die when you want to - but there must be safeguards.
