I am totally in favor of euthanasia under the right circumstances. A nurse tricking someone who is certainly is shock into nodding their heads and saying "ok" is not under any conditions the right circumstances.

I saw you got a downvote, which is a shame, since I think that you made a good point: the importance of assisted suicide as a right should not allow its use to cover any instance of intentional death. However, I think that point might have been based on a misreading of LCDninja's post (https://news.ycombinator.com/item?id=11706159). As near as I can tell, there was no trickery going on, just an honest, if tragic, instance of two people trying honestly to interpret a conversation, but coming to different interpretations about its meaning because the one who understood that there was subtext present could not legally make it explicit.
