Re: Janeway's Decision to Kill Tuvix
I see it as equivalent to any other Trek episode where a crewman is taken over and controlled by a noncorporeal being. Any captain would have tried to get his crewman back. For Janeway, two of the crew were being controlled by a single entity.
Tuvix wasn't an entity that possessed them. Tuvix was a sentient being created from them.
He did nothing to cause it; he was the result.
