Janeway killed Tuvix.
1. Tuvix become a member of the crew, and was given the rank of Lieutenant, nonetheless, Janeway decided it was best to murder him.
2. Janeway doesn't have the right to murder Tuvix, because Tuvix chose to live, and as a rational and sentient being, had the right to life.
3. The Doctor refuses to perform the procedure as it is a violation of the Hippocratic oath and his ethical programming given him by Starfleet. The Doctor knows that this is murder.
1. So were Tuvok and Neelix, in fact the case can be made that Tuvok outranked Tuvix.
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.
Brit said:2. Appearently she does have the right to make that decision, because we do not see Starfleet chastising her for it either, what we know for sure is that she is promoted when they get back.
What Starfleet does or does not do, of course, doesn't change the morality of the issue.
Brit said:I believe both Neelix and Tuvok chose to live too....
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.
Brit said:3. The Doctor has a lot of knowledge all programed into him, and most likely a lot of conflicting knowledge. His decision was pretty immature IMHO....
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.
