Well, we disagree. I don't think this is a situation of impermissable "bad means" for "good end." I think this is morally equivocal means for a good end.
Kervorkian's means was "to end life" in order "to relieve pain." I don't believe there is any comparison between ending a life to relieve pain and giving someone a "stay short" injection to permit a better life.
