The episodes “Death Wish” and “Tuvix” are only a few episodes apart and both weigh the rights of the individual against the needs/desires of the majority.
In “Death Wish”, Janeway rules Quinn has the right to live his life as he chooses, even if that means his own death. Her verdict implies that the majority have no right to tell him how he should live or die and his rights should be protected no matter how they impact society.
In “Tuvix”, Janeway rules that the individual has no rights if it impacts the life and pursuit of happiness of others. If a person’s free will must be sacrificed for the good of others, then it needs to be done.
Did Janeway exercise a double standard in a brief period? Do these cases compare? Does it make a difference that Tuvix was under her command but Q was not?
