Re: Janeway's Decision to Kill Tuvix
Tuvix was an aberration - a sentient aberration, but an aberration nonetheless - and Janeway essentially exercised her right as Tuvok and Neelix's 'legal surrogate' (which, as their Captain, she was by default) to make a choice that they themselves couldn't make, just as a person's 'legal surrogate' would decide whether to put said person on life support or remove said person from life support or to authorize surgery that might correct an aberration in said person's body or brain that might allow them to survive and live a normal life following severe injury.
