I'm not understanding your point. I was establishing that he was indeed a crew member and was even given a rank, therefore he should have the rights of any other crew member. Maybe you can elaborate on your point. What Starfleet does or does not do, of course, doesn't change the morality of the issue. They couldn't choose to live, they weren't there. Janeway assumes Tuvok's and Neelix's desire without evidence. We could well imagine Tuvok arguing that Tuvix combined the abilities of both crew members, but would only require the resources and living space of one crew member, so, logically, he was far more efficient and useful than Tuvok and Neelix as separate beings. We could see Neelix arguing that he liked to be a dynamic duo with Tuvok, all squished into one. They well might have said nothing of the kind. The point is Janeway doesn't know and acts on emotion, not evidence, to murder Tuvix. Ethical programming given him by Starfleet. Brit, a question, now answer honestly, "Would you have given Tuvix due process?" Remember, he had committed no crime, and had expressed a clear desire to live.
