Janeway själv verkar klassificera det som ett mord som gav sitt tal till Vidiiansna i "Phage". Hon verkar ha glömt sina höga principer när Tuvix visas.
So now I am left with the same choice you made. Whether to commit murder to save a life, or to allow my own crewman to die while you breath air through his lungs.
I can't begin to understand what your people have gone through. They may have found a way to ignore the moral implications of what you are doing, but I have no such luxury. I don't have the freedom to kill you to save another. My culture finds that to be a reprehensible and entirely unacceptable act. If we were closer to home I would lock you up and turn you over to my authorities for trial, but I don't even have that ability here, and I am not prepared to carry you forever in our brig.
