You see, I never understood how people could view the situation in "Tuvix" that way. An answer that constitutes of killing an innocent sentient being in cold blood simply CAN'T be the right answer. Sure, not getting Tuvok and Neelix back was very unfortunate, but murdering Tuvix was just all kinds of wrong.There's no right or wrong answer, which is the entire point of the episode.
(As an aside, I can't believe I'm actually posting in yet another Tuvix thread. Seems like there's one every other month.)
