I want to live!
- EvilKirk’s last words
Whatever else you want to say about EvilKirk, it’s pretty clear that he didn’t want to be merged back into the single Kirk. Despite this, there is no shortage of reasons why it was a good idea to merge the Kirks: the Enterprise needed its CO back, GoodKirk wanted to do it, and it seems possible that the strain of remaining split would have eventually killed EvilKirk anyways. However, the fact remains that EvilKirk did not consent to the procedure which ended his existence.
Clearly the circumstances here are quite different and there’s basically no argument to be made that allowing EvilKirk to continue to exist would benefit any involved party, EvilKirk included. But for the purposes of this comparison, the only fact that really matters is that EvilKirk was just as passionate about his desire to continue existing as Tuvix was.
Yet—and it’s obvious where I’m going with this—“Spock murdered EvilKirk” is not a meme.
So what gives? Did Spock murder EvilKirk or not? If yes, why does he get a pass while Janeway is condemned?
It also helps that both good and evil Kirk were slowly dying due to that traumatic separation, hence their need to be reintegrated before it was too late.
By comparison, Tuvix seemed stable, and there was no pressing need to have them be reintegrated before they both died. It seemed uncharacteristically spiteful to have him be forcefully dragged off to be separated with a risky procedure, whilst still begging for his life, with the only words Captain Janeway having about the situation being “sorry, I need my science officer back”.
