Re: Mirror Mirror: Greatest Good?
Could Kirk, McCoy, Scott, and Uhura have done more good if they'd remained in the mirror universe?
Alternate Spock is rational, but he's also a pragmatist, reasoning in terms of self-interest. There is no guarantee that he, for example, spares the Halkans.
I think it's likely that Spock would do exactly that. Remember, the DS9 mirror eps said that Spock reformed the Empire which led to its downfall.
