So you are basically saying as a lifeform Tuvix has no rights what so ever?
since JanewayRulez slid in before you, not sure if this is directed at me or her, but, no, that's not what I'm saying. He has all the rights (The right not to be imprisoned nor abused, the right to a meaningful life while he waits for Tuvok and Neelix to be saved or given up on, etc), except the right to deny Tuvok and Neelix from being saved if possible. Once that possibility is given up, then he also inherits the right to keep the body.
