To start the discussion I do believe that most people can conceive of a
situation where suicide would be a desirable outcome. This situation may
be extraordinary, such as being trapped inside a small box, no light, no
external sound, unable to move a muscle, constantly cramped, and
attached to a feeding tube keeping you alive for as long as possible and
with no possibility for escape.
