i’m not comparing the whole thing; just breaking the problem down into parts… i’m asserting that your definition of “dead” is wrong. they are not permanently dead, because they can be revived
we have 3 potential people. either you remain at the end with 1 person, or 2 people… the choice is between action (killing tuvix to save neelix and tuvok) or inaction (allowing tuvix to live, and accepting the death of neelix and tuvok)
it’s perfectly valid to say that inaction is the ethical choice because you should never personally cause harm… but it’s also perfectly valid to say action (in this case, murder, as we see in the episode) is the ethical choice because it has the greatest good for the most people
and in fact, the latter is repeated often in star trek: the needs of the many outweigh the needs of the few
and indeed, in this episode they further throw a spanner in the works: the many includes voyagers crew, and their chief security officer
