If I knew it was what they really wanted and that they were in their right mind (that raises another question, doesn't it?) when they asked for it, probably. (Also, I'd have to have it in writing, obviously.)
I could never make that decision for someone else.
Edit: Also, I didn't vote in the poll, because, as usual, my answer lies within a gray area. There should be an option that says something like, "I am skirting the actual question by adding my own hypothetical circumstances and saying, 'Maybe;' a.k.a. ambivalence."
