In the case of Tuvix, to me the moral decision would have been to let Tuvix decide his own fate once the option became available. Janeway should have honored his decision, and Tuvix should have been on board for one or two more episodes, with Tuvok and Neelix giving him advice or even tormenting him (perhaps shown as little versions of themselves levitating near his head and talking into his ears (as with Archer in In a Mirror, Darkly before having Mayweather shoot the admiral. And the next time Tuvix beamed down to a planet on an away mission, he would (surprise, surprise) mysteriously materialize as Tuvok and Neelix. Keeping Tuvix as a regular was out of the question, since Tuvok and Neelix would still have to be showing talking in his head from time to time, ending up costing the studio more money in the long run.
