I said equivalent. Yes it was an accident. Yes it was no fault of Tuvok and Neelix. Neither is dying in a shuttle accident. But sometimes it happens. It's also not the fault of Tuvix that he was the result of the accident. He didn't cause the accident, yet you still insist on assigning blame to him for it. Tuvix is a sentient being with all the rights of anyone else, including not to be summarily executed against their will because Janeway decided it serves the needs of the state... which by all means she's the de facto head of out there. The only thing you could condemn Tuvix for is moral cowardice for not volunteering... but last I checked that's not a capital crime.
Keeping something that doesn't belong to you is a crime.
Tuvix's life doesn't belong to him? So now we get to it... you endorse servitude and slavery in the name of authority just because he's different?
