Being anti death penalty even for multiple murderers, no. (Also: Khan's crewmembers are responsible for whatever they did 300 years ago, but not for Khan's actions while they were frozen, so I don't see how you'd justify them being shot into Sol along with him even from a pro death penalty pov, and you wrote "cyrotubes", plural.)

McCoy in charge of the cyrotube/torpedo stuff: now that you mention it, probably. I only watched Undiscovered Country twice due to my strong dislike of the film, once in the cinema and once when it got broadcast on tv to see whether I hadn't softened towards it, and I hadn't. Both was more than 15 years ago.
