How we cite our quotes: All quotations are from Star Trek III: The Search for Spock.
Quote #1
KIRK: No. More empty even than that. The death of Spock is like an open wound. It seems that I have left the noblest part of myself back there on that newborn planet.
Spock's choice to sacrifice himself and implant his katra into McCoy looms large over this film. In fact, this story is really about Kirk and his crew dealing with the consequences of that choice while Spock enjoys a staycation chillin' in McCoy's brain space.
Quote #2
VALKRIS [in Klingon]: Success, my lord, and my love.
KRUGE [in Klingon]: You will be remembered with honor. Fire!
Kruge can't make a decision that doesn't end in someone dying. It's like he has some kind of villainous death quota to meet. That's because, unlike Kirk, who makes choices based on what he feels is best for others, Kruge's choices stem from what is best for Kruge. Everyone else is incidental cannon fodder.
Quote #3
DAVID: Why don't we beam it up?
ESTEBAN: Oh, no, you don't. Regulations specifically state, "Nothing shall be beamed aboard until danger of contamination has been eliminated."
SAAVIK: Captain, the logical alternative is obvious. Beaming down to the surface is permitted.
ESTEBAN: If the Captain decides that the mission is vital and reasonably free of danger.
DAVID: Captain, please, we'll take the risk, but we've got to find out what it is.
SAAVIK: Or who.
Captain Esteban is a by-the-books leader. Every choice he makes is designed to skirt personal responsibility and place the burden on the rule book. In a universe where decisions need to be made quickly and consequences can be messy, this doesn't make Esteban the most effective of captains.
