Sparing the Aces

Mitth'raw'nuruodo, brilliant tactician. Equally brilliant strategist. A being who could take on Republic warships, nomadic pirates, and even Jedi, and win against them all. And Doriana was actually considering killing him?
Doriana: [puts blaster down] Don't be absurd, Vicelord. I would sooner shatter a thousand-year-old crystal as kill a being such as this.
Thrawn: So I was indeed right about you.

Alice is a once-in-multiple-lifetimes genius at something. What it is doesn't matter - a brilliant general, a mathematician, a painter. Bob has a very good reason to want to kill her and is in a position where he can easily do so. He decides against it despite the fact that he could safely get away with it.

Why? Because the life of someone so brilliant has intrinsic value, and he doesn't want to deprive the world of it. Some overlap with Kill Me Now or Forever Stay Your Hand, and a sister trope to Uniqueness Value. While that trope demands uniqueness, this one required exceptional genius at something in particular—if there happened to be five brilliant physicists, the character acting out this trope would still have as much trouble killing them as if there were only one at that level.

Frequently, the "genius" in question becomes a Morality Pet. A subtrope of You Will Be Spared.

  • Fist of the North Star: Hokuto Shinken tradition states that those students who do not become the successor must renounce Hokuto Shinken or have their fists destroyed so as not to be able to use it. However, Toki alone was spared this fate for myriad reasons: first, he is a true prodigy among the art's millennial history and it'd be a loss to it for him to not be able to use it; second, his radiation sickness disallows him from challenging the successor and saps much of his physical might; and third, Toki does not use Hokuto Shinken as a fighting art, but as a healing art. While Raoh uses Hokuto Shinken because he disregards its rules, Toki uses it because he's just that special and important to Hokuto Shinken.
  • Played with in the 'ant' arc of Hunter Hunter. First, all the humans in the country the King has taken over are to be tested to destruction in such a way that the most potentially powerful can be converted into the superpowered mindslave footsoldiers of his world conquest. Then to keep him busy for a few months while they get this plan into operation, his bodyguards start bringing the most accomplished strategy gamers they can find; once he beats the national chess champion, the man is killed and eaten, et cetera. Then he can't best this blind girl with a runny nose, Komugi, and starts to get obsessed with doing so. That's all stage one.
    • Stage two, she starts visibly improving in response to his challenge, and he comes to the thoughtful realization that human beings have an endless and mysterious potential to improve, and that child that he ate on the way to the palace might have had the potential to exceed him, the King, in some particular way. His bodyguards are at this point in the speech freaking out at what looks like an impending Heel-Face Turn... and then we get a giant Slasher Smile and the declaration that if they are all that, and he can kill any of them, that makes him even more supremely awesome than he'd realized.
    • Stage three, he develops even more respect for Komugi and some form of emotional maturity (the guy is three months old), which combined with his appreciation for the skill and determination of the Hunter strike force, or at least Netero, prompts him to offer very reasonable terms, which are not accepted. He eventually dies of radiation poisoning inflicted by Netero's dying act, while playing against Komugi. He never did beat her.
    • The King's arrival at any kind of civilized interaction with humans was thus built on a foundation of this trope, via Komugi and Netero.
  • Tower of God
    • Ultimately subverted when Ren admires Baam's incredible talent and would love to recruit him into the Royal Enforcement Division, but decides to still kill him.
      Ren: It's really a shame...but I can't let an Irregular live.
    • Played straight when Love, despite his desire to enact his revenge on the organization Viole belongs to, decides to spare him out of curiosity where his immense talent will take him, under the condition that Viole renounces his affiliations with FUG.
  • Joseph Joestar convinces Wham to spare him with a variation of this sort of argument in Part 2 of JoJo's Bizarre Adventure. Realizing that Wham's a Proud Warrior Race Guy who wishes to fight a Worthy Opponent, he suggests that maybe it'd be worth sparing the one guy who has a chance of becoming that.
    Joseph: I was just thinking about how you're going to have to live the rest of long life always thinking about that how you were injured by a human. The only way to get over that... well, would be to fight a properly trained me, is what I was thinking.
  • Happens in Dragon Ball at the climax of the Saiyan Saga: After pushing Goku to use Kaio-ken x3, blasted into the stratosphere by by Kaio-ken x4-charged Kamehameha, having his tail chopped off, hit with the Spirit Bomb, having his back cut and crushed by a Giant Ape Gohan falling on him; Vegeta still had enough strength to crawl back to his space pod. While briefly impressed with his sheer resilience, Krillin decides to kill him with Yajirobe's sword to finally end the Saiyan threat. But Goku calls out to Krillin to ask for Vegeta's life to be spared, since he admired his incredible strength, and thought it'd be a waste to deprive the universe of such a strong warrior, and while not convinced he'd turn like Piccolonote , he wished to have the opportunity fight him once again, Krillin accepts Goku's request.
    • Frieza, despite being a paranoid racist, did this to fighters he found especially strong and talented. It was the primary reason why he spared Vegeta when he destroyed the Saiyan's home planet. He offered Goku to come into his service, saying that it would be a waste to destroy such talent and was quite upset when he got turned down. He also lamented what a shame it was to kill Nail when he saw how powerful he was.
  • In Bleach, it's been revealed that Kenpachi subconsciously does this. He enjoys a good fight so much that he holds the majority of his power back from fear that he will kill anyone talented enough to challenge him.
  • In Naruto flashbacks, it's shown that before Hanzo became paranoid and power-hungry, he used to spare the lives of enemies strong-willed enough to put up a good fight against him.

  • The Princess Bride: The Man in Black declines to kill his Worthy Opponent Inigo Montoya because Inigo is an extremely gifted swordsman who has made swordfighting his life's study in order to be able to one day avenge the man who killed his father. Not only that, but Inigo had plenty of chances to easily kill the Man in Black, but chose not to, out of a sense of honor.
    The Man In Black: I would as soon destroy a stained glass window as an artist like yourself. However, since I can't have you following me either... (Tap on the Head)
  • In Hellboy II: The Golden Army, Prince Nuada pulls this gambit to try to turn Hellboy over to his side. It rings just a little bit false, because Nuada himself unleashed the creature in question as a weapon.
    Nuada: What are you waiting for? This is what you want, isn't it? Look at it. The last of its kind. Like you and I. If you destroy it, the world will never see its kind again...
  • In The Silence of the Lambs, Hannibal Lecter spares Agent Starling for precisely this reason.
    Clarice Starling: Where are you, Dr. Lecter?
    Hannibal Lecter: I've no plans to call on you, Clarice. The world is more interesting with you in it.

  • Jeane-Claude of the Anita Blake series says he doesn't turn people often because he doesn't like the idea of taking a great artist or mind—and though vampires don't die, he says they get a good dose of Creative Sterility.
  • Outbound Flight:
    Mitth'raw'nuruodo, brilliant tactician. Equally brilliant strategist. A being who could take on Republic warships, nomadic pirates, and even Jedi, and win against them all. And Doriana was actually considering killing him?
    Doriana: [puts blaster down] Don't be absurd, Vicelord. I would sooner shatter a thousand-year-old crystal as kill a being such as this.
    Thrawn: So I was indeed right about you.
  • This happens in Salamander, where Ellen is explaining why she hasn't killed Coelus.
  • In Gillian Bradshaw's The Sand-Reckoner, Hieron of Syracuse says this about Archimedes.
  • The Ace of Labyrinths of Echo series by Max Frei was convinced that the life of people who show a talent for the magic using forces of the Universe — as opposed to forces of the world, which anyone can in a magical enough place — is "almost sacred". Which is why he devised a complicated trap to capture the Big Bad instead of killing him. That's the man who slaughtered so much powerful mages that he became the most feared and hated being for the magical Orders in the middle of a civil war despite pretending he's no one's enemy and kills just for money (they still hired him, of course).
  • In Memory, Sorrow and Thorn, this is part of the reason why Prester John spares Camaris. Camaris was widely considered to be the greatest knight who ever lived, with John being the only one who had a chance of holding his own against him in battle.
  • Discworld's Havelock Vetinari can be ruthlessly pragmatic at times, so this is probably why he keeps Leonard of Quirm in a Luxury Prison Suite instead of having him executed. Leonard is a genius capable of drawing the blueprints for devices that would deliver explosive payloads to the other side of the Disc, and naive enough to think that no person would be cruel enough to use them on other people. Still, some of the other things he doodles can be benign and/or useful, and sometimes Vetinari needs someone utterly guileless to talk to.

  • Doctor Who: In The Seeds of Death, The Doctor invokes this when captured by Ice Warriors.
    Doctor: You can't kill me! Your leader will be very angry if you kill me! I'm a genius!
    • Played with in "Asylum of the Daleks." The Daleks have an entire planet for Daleks they deem too insane or out-of-control to be of any use. When asked why they don't destroy these mad Daleks, as they tend to do to anything they feel has outlived its usefulness:
      Dalek Prime Minister: It is offensive to us to extinguish such divine hatred. (...) Does it surprise you to know the Daleks have a concept of beauty?

  • In Erfworld, it is impossible to intentionally create casters, so they are usually captured rather than croaked when their side is destroyed.

    Real Life 
  • Operation Paperclip was a secret mission by OSS (CIA's predecessor) to extract German rocket scientists and medical doctors after World War II to the US, regardless of their past affiliations with the Nazi party or even war crimes.
  • The Greek mathematician Archimedes was supposedly killed by a Roman soldier despite orders that he not be harmed.
  • The Colombian ecovillage of Gaviotas woke up one morning to find that they'd been occupied by the FARC. The heavily armed guerrillas lined all the villagers up and demanded that they declare their allegiance. One of the villagers stepped forward and said that they had no allegiance save peace, and would take no sides in any armed conflict. "What," she asked, "will you do to us now?" "Nothing," came the reply. "We have orders to hurt no one here. What you're doing is too important."
