How can it be selfish if a person wants to survive? It would have been different if Tuvix's death actually served some other purpose than to make the crew feel better - so, who's selfish there? IMO a crew who can't cope with two of its members gone isn't the most stable crew anyway.
As I said, it's not about who's there and who's gone. It's about trust, an absolutely vital commodity in any team. These people had to believe they could trust one another with their lives, had to know their crewmates would put their own lives on the line for their benefit. Tuvix's actions would've created doubt in the crew's minds about whether he was capable of that. It doesn't have to be a huge degree of doubt; it could be a very subtle, back-of-the-mind sort of thing. But in the exceptional circumstances of Voyager's situation, with a crew that might have to spend the rest of their lives together and didn't have the luxury of transfers and crew replacements to deal with interpersonal tensions, even such a subtle seed of mistrust could fester and grow over time.
And again, I'm not saying this is what I believe. I'm evaluating this objectively. I'm just saying that, in my attempts to reason out what Janeway's decision process must have been and why she made the choice she did, this is my best estimation.
I definitely don't agree there. There was no crisis situation when Janeway ordered Tuvix to die. The crew's livelihood wasn't threatened in any way.
I never said it was. I'm not talking about events, I'm talking about emotions. You could see it in the way the scene was written and directed, the way the actors played it -- when Tuvix refused to sacrifice himself, the rest of the crew turned against him. They'd liked him before, but now they soured on him. That's what I saw in the performances, in the onscreen action, and that's the basis for my hypothesis about what Janeway's decision-making process was.
They would have needed time to come to terms with reality but in the end they would have come to terms with it and let go.
Tuvix never would have hesitated to lay down his life if there had been a real threat to the crew. I don't think that the crew doubted that if they had taken a step back and actually thought about the situation.
You're approaching this as if the whole thing were a completely rational, surface-level decision process that everyone in the crew would be consciously aware of. People's minds don't work that way. They have subconscious reactions to things. One person's trust in another can be poisoned in ways they aren't even cognizant of. No matter how much they intellectually rationalize things and decide they're acceptable, they may still have underlying emotions that say just the opposite. Especially in a case like this, where we're talking about the life or death of their friends and coworkers. That's an incredibly traumatic thing. You can't just "get over" something like that by intellectually rationalizing it.
Honestly, I rather think that not so important crewmembers should consider the fact that they could be sacrificed needlessly, just to make the higher-ups happy. Talk about a boost of morale.
That's completely unfair. What I'm saying is that Janeway made the choice she felt was best for her entire crew, because that's what captains do. You just can't toss out pat caricatures and oversimplifications here. The moral dilemma of "Tuvix" is brilliantly complex and challenging, and you can't sum it up with sound bites.
