No it doesn't, the issue is did Janeway have the right to murder Tuvix by forcing him to undergo something against his will.
Did Tuvix have the same rights as any other Federation Citizen?
If not what rights does he have?
If he does not have the same rights as other Federation Citizens, Why is he not afforded them?
Why are Tuvok and Neelix's rights not part of the picture to you?
Tuvix is kind of an accidental body-snatcher/organ-harvester here.
