Apparently some people just don't see choosing when you die - natural outcome of a terminal disease VS personal choice to forgo that particular end - as a right or a means of maintaining good mental health or dignity.
Suffering is the only thing that's healthy?
Suffering is the only form of dignity?
What about other people wanting someone to suffer and agonize to the end? Where's the dignity in craving that?
If it's legal for doctors to devise medicines and means of killing convicted murderers, commit abortions, then I don't see how assisting someone who's life is coming to an end with a means of having a more dignified and less horrific end is all that bad.
