Surely, the point is that nobody is killing anyone, but rather under certain extreme circumstances we have the option to take our own lives.I think it is a strange juxtaposition, that a secular society that, in living memory, has quite rightly come to the conclusion that the state has no right to execute murderers; should now be countenancing killing some of its sick.
I'd hope never to have to use it, but knowing the option is there would help, even if I didn't use it.
