so if you tuvixed neelix, would that be splitting neelix into two separate people, nee and lix? in that scenario putting them back together would be ending two lives for the sake of one life, making it kind of the opposite of the original tuvix situation where youre sacrificing one life for two. then again we have to consider that the person we’re saving is neelix in that scenario, so on the whole it might be better to leave him separated.
