For whatever reason -- someone is magically divided into their "light" and [[EvilTwin "dark" halves]], or an encounter with a SufficientlyAdvancedAlien -- the cast and crew have to deal with a "pure good" (and occasionally an identically powerful pure evil) entity.

Regardless of the circumstances, [[StupidGood the pure good entity will be a complete and total wuss. Militant pacifist, empathic to a ridiculous degree, incapable of defending itself, and generally utterly useless]] till the main cast reunites it somehow with its evil, depraved and (of course) effective and proactive side.

This probably accounts for the shock and horror with which most {{Media Watchdog}}s greet heroes who are, shall we say, [[AntiHero less than touchy-feely about how they deal with the villain of the week]]. "Good," after all, is supposed to be NICE. [[GoodIsNotNice Right]]?

The seeming impotence of Good in general might be because [[GoodHurtsEvil good no longer hurts evil]]. May explain why the BalanceBetweenGoodAndEvil is needed because [[VillainsActHeroesReact Evil will get things done]], while the presence of Good reins in the {{ambition|IsEvil}} to prevent harmful and destructive actions, thus ensuring that Evil's proactivity will be channeled into things of which Good approves.

In a meta sense, this trope is used because a good character that is suddenly made extremely powerful and deadly can tip the scales too heavily in the favour of good. While this might not be so bad if the writers make it so the villains work at meeting the hero at the same level, more often it makes the good side into {{Invincible Hero}}es. On that same note, concentrating, increasing and highlighting all the positive aspects of one character without [[PowerCreepPowerSeep upping the ante all-round]] and doing the same to the other characters can only lead to [[GameBreaker one]] [[MarySue thing]].

Can sometimes happen when a character [[AscendToAHigherPlaneOfExistence ascends to a higher plane of existence]], and later finds out that when you're Ascended you can't actually ''do'' anything because of [[ObstructiveCodeOfConduct The Rules]].

For when Good can actually do stuff, see HolyHandGrenade.

Compare GoodIsBoring, RedemptionDemotion, TheGodsMustBeLazy, BoringFailureHero. Frequently includes an inversion of EvilCannotComprehendGood. For when the impotent good is one of two or more personalities, see HelplessGoodSide. A CluelessBoss may contribute to this.

And no, [[IThoughtItMeant we don't mean]] ''that'' kind of "[[TheLoinsSleepTonight impotent]]". After all, GoodPeopleHaveGoodSex.


[[folder:Anime and Manga]]
* The entire series of ''Manga/{{Othello}}'' is based on this trope, albeit the "evil" Na-na is different personality and not a literal "new" version of Ya-ya.
* ''Manga/DragonBall'':
** Buu's internal conflict splits him into good and evil halves. While good Buu is far from impotent, he is still bested by his evil side and is absorbed into the more powerful Super Buu. Later on, when Buu is extricated from Super Buu, it is revealed that "Fat Buu" was created when the Grand Supreme Kai was absorbed by the original, pure evil, Kid Buu.
** Earlier, Kami splits into a good and evil half to ensure that he could work as Earth's "God" (God in this series is actually a [[GodJob job position]]) without the evil in him causing him to abuse his power. The evil half that becomes Piccolo Daimaou is not, as far as the audience can see, actually any stronger Kami, but Kami is a NonActionGuy so it's rather academic. The 2nd Piccolo ''is'' stronger due to a combination of youthfulness and an inversion of VillainForgotToLevelGrind.
* In one ''Anime/{{Slayers}}'' made-for-video movie, a magic mirror creates [[EvilTwin opposite clones]] of Lina Inverse and Naga. To the villain's horror, these turn out to be simpering, useless "good" copies that won't fight. This leads to his ''greater'' horror when he realises what this must make Lina.

* ''ComicBook/TheLeagueOfExtraordinaryGentlemen'''s Dr Jekyll and Mr Hyde are the embodiment of this trope, in one package. Hyde even explains to the rest of the League why he has been getting stronger and stronger while Jekyll had been getting correspondingly weaker: as the embodiment of Jekyll's id, Hyde has all the drive and ambition, leaving Jekyll with nothing.
* In ''Comicbook/{{Watchmen}}'', the superheroes come in three flavors: sympathetic and ineffectual, sociopathic and effectual, and [[PhysicalGod Dr. Manhattan]], who is all over the map depending on how "into" humanity he's feeling this week. Nite Owl is the [[TheLoinsSleepTonight other kind of "impotent"]] as well and given the nature of the work, this is almost certainly intended to be symbolic.
* The Italian comic [[https://en.wikipedia.org/wiki/Tiramolla Tiramolla]] features a three-person variant. AppliedPhlebotinum splits the protagonist into three individuals possessing all of the original's strength, cunning and kindness, respectively: the first is a brute who wreaks havoc in the city [[BloodKnight looking for an adversary]]; the second [[TheTrickster plays pranks on everybody he sees]]; the third is an ineffectual dreamer who recites poetry and does bird-watching, oblivious to the mayhem caused by the other two. The predicament is solved when the AppliedPhlebotinum is used to fuse the second and third personalities together, creating someone who is [[GuileHero both willing to save the town from the brute and smart enough to pull it off]].
* In the French-English comic ''ComicBook/RequiemVampireKnight'', Résurrection is a Hell-like dimension where evil people reincarnate as hideous monsters and split into different categories according to their sins in life. The closest thing to a "good" faction in this world are the [[OurGhostsAreDifferent lamias]], who did not commit any real crimes in life, but they are [[CrapsackWorld sentenced to this world regardless because they were victimized by someone else that did became a monster]] and the only way they can leave Résurrection is to destroy the one responsible. They are among the weakest creatures in this setting, only slightly above [[OurZombiesAreDifferent zombies]] and make up a significant portion of the slave population, with the most beautiful and not yet bitten female lamias being forced to join Count Dracula's harem. On their own, they are only capable of spooking their tormentors in their sleep and depend on mind-controlling other creatures such as centaurs and werewolves (i.e. other evil individuals - rapists and religious zealots, respectively) to really make a difference. And even then, that doesn't mean much since the vampires (Résurrection's elite made up of the most depraved individuals to ever live) are more advanced in every single way.

* Subverted in ''Film/ArmyOfDarkness''. "Good, bad, I'm the guy with the gun."
** Better illustrated by the director's cut version of the line: "I ain't ''that'' good."
* Superman was affected by a different kind of kryptonite, and winds splitting him self in to good who is Clark and bad as Superman, the good part of him took one heck of a beating in ''Film/SupermanIII'' -- for a while, and gets back up for a second wind.
* In ''Film/MeMyselfAndIrene,'' the whole reason Charlie's psyche creates his evil alter-ego Hank is because Charlie's too much of a nice guy to stand up for himself.
* In ''Film/TheDarkCrystal'', the wise and gentle urRu and the cruel Skeksis [[spoiler: were split from a single race of beings]], the urRu retaining their wisdom, benevolence and purpose but lacking the will to take action, while the Skeksis retain their strength, force and willfulness but lose their wise and compassionate natures and devolve into a DeadlyDecadentCourt.
* The basic message of many of Creator/RomanPolanski's movies, with ''Film/{{Chinatown}}'' being perhaps the most infamous. This was especially the case after his wife Sharon Tate's brutal murder, although it was evident as early as ''Film/TheFearlessVampireKillers''.
* Done very subtly in ''Film/TheGoodTheBadAndTheUgly''. Most of the characters and plot are stuck firmly into a BlackAndGrayMorality setting. The few truly good characters such as the priests or the Union Commandant are either helpless to change things or relegated to standing on the sidelines while the Black and Gray characters run things.
* Sheriff Ed Tom Bell in ''Film/NoCountryForOldMen'' is utterly impotent in his attempts to catch Anton Chigurh.
* Somewhat the point of ''Film/DemolitionMan''. In the future San Angeles, society has banned everything and anything that can possibly harm or offend anybody: guns, alcohol, swearing, [[WellIntentionedExtremist caffeine, sexual intercourse (and physical contact too), chocolate, speeding, spicy food]]... The downside to this city of [[PoliticalCorrectnessGoneMad Politically Correct]] PerfectPacifistPeople is that when AxCrazy criminal Simon Phoenix is thawed out of cryostasis, the wimpy police of the future have absolutely no idea how to deal with his old-school brutality, and Phoenix runs amok. Hence, they need to thaw out tough CowboyCop John Spartan to deal with Phoenix and save the day.
* ''Franchise/StarWars'' is a deliberate subversion. At the peak of their power in the Prequel Trilogy, the Jedi were virtually helpless against the Sith's plans and wound up [[NiceJobBreakingItHero helping]] to create the EvilEmpire before they were wiped out themselves. However, Luke changes tactics and manages to triumph over the Sith in the Original Trilogy. The Sequel Trilogy sees a new Dark Side order [[spoiler: wipe out the fledging Jedi Order once again]], which prompts Luke to become a mentor to [[TheHero Rey]]. Darksiders will go on and on about the [[LoveIsAWeakness weakness]] of the Light Side and they have some good points, but the truth is both sides evolve to meet new threats and [[BalanceBetweenGoodAndEvil neither can truly destroy the other]].

* The ''Literature/{{Animorphs}}'' book ''The Separation'' {{avert|edTrope}}s this with Rachel--neither sides are explicitly good or bad. They each got half of the components of her personality at random. The "good" side was given Rachel's tactical and strategic abilities, leaving the "evil" side with just the blood rage and ability to fight. The end of the book results in the evil Rachel grudgingly having to work alongside the good Rachel because evil Rachel can't plan or strategize worth squat, so is totally unprepared for any reaction to changing battle situations other than "kill something."
* Subverted in ''Literature/AWorldGoneMad''. Wally's evil half is lazy, hedonistic, and has zero impulse control, spending all his time chasing women and watching TV. Wally's good half is proactive and driven to actually solve the problem at hand (to relieve the suffering of others). The good half probably has an aversion to violence, but since Wally's a stealthy-type "sneaker" that's not really an issue anyway.
* Played with in ''Il visconte dimezzato'' by Italo Calvino. When the protagonist is split in two halves, one good and one evil, the evil side is a ruthless bastard, while the good side is kind and generous but rather ineffectual.
* In ''Literature/TheLordOfTheRings'', the FallenAngel Sauron is busy conquering and wrecking the place up while his good counterparts are limited to guiding and influencing the Free Peoples and are forbidden to try to match him strength-for-strength. This is less because they're weaker and more because the last time the Valar took on the BigBad directly, the resulting battle leveled a few major continents.
* In ''[[Literature/AWrinkleInTime A Swiftly Tilting Planet]]'', this is somewhat averted: the "good" people are proactive, strong, and willing to face evil, at least to give it a stern talking-to. But the wicked people are tolerated in the communities because they're ''better at things'' - one woman who is racist against Indians is the best midwife in the village, and Gedder the evil sumbitch is able to teach others how to farm.
* Most any portrayal of a stereotypical angel. Ironic, since in [[Literature/TheBible Judeo-Christian scripture]], angels are portrayed as warriors or executioners just as often as they are as messengers, and usually have to tell any humans who recognize what they are not to be afraid.
* Lord Vetinari claims this to Vimes in ''Discworld/GuardsGuards'' ("A great rolling sea of evil ... but people like you put together little rafts of rules and vaguely good intentions and say, this is the opposite, this will triumph in the end, Amazing!"). Vimes's entire subsequent career proves him wrong.
* ''Franchise/StarWarsExpandedUniverse'': This and GoodIsNotNice is what usually leads to Jedi purges. In many eras, Jedi candidates are harvested from infancy or early childhood, cut off from and forbidden "attachments" (family, love, and any close bonds) or strong emotions, cultivated in relative isolation in temples and enclaves, and restricted from anything that challenges the prevailing dogma unless they're Master rank. This is all to make it so the product of this system never succumbs to the Dark Side. Then, they're sent out into the galaxy into the thick of galactic conflict as fighters (who can't strike unless in defense), exposing them to things that would make Audie Murphy wince, while being forbidden the comforts that even a common soldier would get (like friends, lovers, or a family to come home to)...And then The Order ''wonders'' why so many of them snap and start carving up planets?
* ''Literature/GreenSkyTrilogy'': While it's not so much "good" as "good intentions," the Kindar have done such an awesome job of banishing conflict, crime, and [[{{Newspeak}} even words like "anger,"]] that their society is killing itself. Their Erdling counterparts are still hippies by our standards, but their acceptance of their emotional darker side makes them more robust.

[[folder:Live-Action TV]]
* The classic ''Series/{{Star Trek|The Original Series}}'' episode ("The Enemy Within") where a transporter accident lead to Kirk getting divided into "good" (peaceful, passive, considerate, pacifist) and "evil" (violent, resolute, egoistical, aggressive) selves. What makes this the poster child for this Trope is that the "Evil" side does learn to calm down and even assumes command for a short time, while the "Good" side remains unable to make the simplest decisions (though downplayed in that the episode doesn't ''call'' it Kirk's good and evil sides, it just ends up that way based on the division of traits). Notably, though, the "Evil" side ultimately turns out to be a total coward when the chips are down, falling into a useless panic at the thought of losing independent existence, something the "Good" side can calmly accept.
* ''Series/BuffyTheVampireSlayer'' subverted it: A demon splits Xander into two, but while one half is meek and the other assertive and strong, neither is "good" or "evil" (although both are convinced that the other half is the demon [[WrongGenreSavvy presumably because they've seen this plot before]]).
** And both sides love Anya and try to protect her from the other one. Before they get put back together, Anya expresses an interest in trying out [[TwinThreesomeFantasy having two Xanders…]]
* In the ''Series/RedDwarf'' episode "Angels & Demons", the ship ''Red Dwarf'' and everything on it was triplicated, but into good and evil versions. The good versions, of course, not only couldn't fight, but couldn't conceive of the idea of anyone intentionally causing harm. Needless to say, they didn't survive too long.
-->'''High Kryten''': Poor devil must have a faulty gun. He's accidentally shot me five times. Oh, how I love him!
-->'''High Lister/Rimmer''': "Apologies, brother. I seem to have stained thy knife with my blood. Allow me to furnish you with a fresh knife."
* On ''Series/AmericanGothic1995'', no matter how hard Dr. Crower and Gail fight for Caleb's rights, and no matter how much Merlyn uses her angelic powers to protect him, Caleb is inexorably drawn into Buck's orbit and everyone seems helpless to prevent it, or even expose Buck's evil. It doesn't help that the sheriff is a VillainWithGoodPublicity and that both Matt and Gail are hardly immune to mind games or [[EvilIsSexy temptation]], but even Merlyn is made out to be decidedly weaker than her adversary--and gaining more power to face him [[NotSoDifferent almost pushes her too far]].
* The ''Series/{{Constantine}}'' has the angel Manny who shows up to give Constantine cryptic advice or say how he cannot do anything that would interfere with human free will. This prohibition is so strong that he is powerless to do anything against the demonic forces terrorizing humanity and interfering in free will by possessing humans against their will. Essentially, evil can do whatever it wants and the angels cannot do squat including rescuing an innocent girl's soul from {{Hell}} forcing them to rely on a broken mortal and the threat of eternal damnation to make sure he is motivated.

[[folder:Video Games]]
* In ''VideoGame/{{Xenosaga}}'', chaos all too often comes across as an indecisive wuss where as pretty much the whole series is a EvilPlan by his dark twin Wilhelm. Some people even suspect that Wilhelm?s true goal was to force chaos to make a decisive choice by attempting to make that choice for him.
* In ''VideoGame/TalesOfLegendia'', Grune turns out to be the opposite force to [[spoiler:Shwartz]], but is obviously weaker, from her amnesia to her lacking the power to beat her archenemy by herself. (Something obviously happened to cause this, but the game never explains it.)
* ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'' plays this mostly straight, as Emil is a cowardly little runt who can barely swing a sword while his "[[SuperpoweredEvilSide Ratatosk Mode]]" is a cruel and powerful BloodKnight. [[spoiler:Subverted in the closing act of the game when Emil seals away his Ratatosk personality and turns out to be just as powerful. In fact, his Mystic Arte has been confirmed statistically to be more powerful than Ratatosk's even without the latter's extension.]]
* In the ''VideoGame/BlackAndWhite'' series:
** Good gods are fairly restricted in the first game: they take longer to set up their power base, are much easier to impede, and have to cooperate with the villagers' desires rather than bend their godly power towards dominating the land. Moreover, evil gods get easy access to offensive miracles that are a much more efficient use of power than the defensive abilities of good gods. While evil play isn't sustainable in a level over the long term, its strategy of taking the land by force and moving on to the next conquest makes that almost irrelevant.
** Greatly mitigated in the sequel: good gods rely on impressing the enemy into switching sides, so they can focus their abilities on becoming powerful {{Barrier Warrior}}s who build up an idyllic ShiningCity behind unbeatable defenses. Its ''Battle of the Gods'' expansion even adds a non-evil way of wiping out entire enemy armies in the form of a permanent mass BalefulPolymorph miracle, for those too pure of heart to KillItWithFire.
* Implied in ''Star Wars: VideoGame/KnightsOfTheOldRepublic'' somewhat. In a gang war between the 'good' Hidden Beks and 'bad' Black Vulkars, the good guys are losing and they're the side you have to join. Also, the good guys are losing at the beginning of the game when the Endar Spire is overtaken by the Sith. Finally, Malak, the 'DarkLord' and BigBad of the game does a good job conquering most of the galaxy and has an army of loyal {{Mooks}}. Might makes wrong in Star Wars, it seems.
** You can actually [[DiscussedTrope discuss this with Carth]], who points out that Malak hasn't won ''yet'' and probably was only winning because of the foundation Revan built. [[note]] The Republic being weakened by the Mandalorian Wars while it's still recovering from Exar Kun's War also factored in; the latter is why the Jedi didn't want to throw support into the former, inadvertently [[NiceJobBreakingItHero making the situation much worse]]. And as passive as the Jedi were, they were unfortunately ''right'' about Mandalore the Indomitable being a pawn of the Sith Emperor. Revan also had a [[AbusivePrecursors Rakata]] factory capable of cranking out entire ''fleets'' of warships, droids, and weaponry at the push of a button while the Republic had to ''build'' everything from the ground up. [[/note]] It's also known that Revan was defeated, costing the Sith their competent leadership - Malak is so StupidEvil that his tactical sense only goes as far as "burn the whole planet." Carth also remarks in the tomb of Ajunta Pal that the Dark Side's weakness is that it eventually consumes itself.
** It also factors into the backstory, especially if The Exile is arguing with Atris or one of the other lost Masters. The Jedi were busy navel-gazing while Mandalore the Indomitable was leading his people on a rampage that got as far as Duro. Had Revan ''not'' disobeyed the Council by going to war, then the whole galaxy would have either speaking ''Mando'a,'' and/or been a satellite state for the True Sith.
** {{Subverted}} come the sequel ''VideoGame/StarWarsTheOldRepublic''. Yes, the Empire managed to catch the Republic with their pants down (because Revan and Exile had a masterful grip on the IdiotBall and the Republic had ''no'' idea that they even existed). But then, there's a treaty that's about as strong as toilet paper that both factions treat with the same amount of respect. [[AwakenTheSleepingGiant Still, it allows the Republic necessary time to regroup]] while the [[ChronicBackstabbingDisorder Sith predictably start infighting.]] The Republic has a bigger population, better developed infrastructure, rule of law (Senators can be crooked, but they can also be removed from office and sent to jail), and are smart enough to keep the wizards out of government for the most part. The Empire is "run" by an OmnicidalManiac, "administered" by a theocratic cabal of AxCrazy sorcerers (with the only qualification for advancement is [[KlingonPromotion "I stabbed the other guy first"]]), has the infrastructure of a Third World backwater, relies on slave labor (and wastes the talents of anyone who isn't human, Sith species, or Chiss by sending them to the auction block), lower population, etc. An ''individual'' Imperial is probably a little tougher than their Republic counterpart because of HadToBeSharp, but overall? The Empire ends up doing more damage to ''itself'' than the Republic, and is on the verge of collapse come the Makeb arc.

* There is a comic where a guy gets split into not two, but four parts of himself. Thus, there were two 'goods' and two 'evils'. But while one 'good' was indeed, rather wimpy, that part also had his [[UnstoppableRage rage]]. The other 'good' fought for [[KnightTemplar justice]], but had no sense of mercy. Of his 'evils', one was just a {{jerk|WithAHeartOfGold}}, but was also the one with all of the humor, while the other 'evil' was bloodthirsty, but was also rather [[BigBrotherInstinct protective]] of his friends.
* In ''Webcomic/{{Polandball}}'', the European Union, United Nations, and the [[PosthumousCharacter League Of Nations]] are generally well meaning, but completely ineffective at stopping AxCrazy countryballs like Nazi Germany. The UN is armed with a squirt gun to punish those who misbehave.
** This is [[DeconstructedTrope deconstructed]] tragically in [[http://i.imgur.com/KzktmGF.png this]] comic. [[spoiler:The UN doesn't see itself because it doesn't need to exist in a peaceful world.]]

[[folder:Western Animation]]
* TheDisneyAfternoon cartoon ''WesternAnimation/DarkwingDuck'' featured an episode of this: Darkwing was hit by a beam that divided him into his "positrons" and "negatrons", resulting in him dividing in two. The "good" version was treacly, cloying, and so nonviolent he refused to even step on bugs... and of course useless in the effort to round up the evil version. However its arguably Downplayed, as the Good version proves to be BadassPacifist, who manages to single handily save himself, Gosalyn and Launchpad from his evil Counterpart's death trap.
** On top of that, the episode in question ''eventually'' averted this. Negatron-Darkwing gets hit with the splitter beam, which rather than splitting him again results in his evil getting even more concentrated, and suddenly he can shoot lightning bolts out of his fingers, throw cars with his mind, and cause earthquakes without even trying. It looks like he's given up on merely robbing banks and is about to destroy the city just to laugh while it burns, when in desperation Goslyn decides to zap the useless Positron-Darkwing with the splitter. What happens after that looks like stock footage from ''Anime/SailorMoon'', but it works.
* Inverted in ''WesternAnimation/XiaolinShowdown'', where the good Jack Spicer is far more effective at fighting than he was when he was evil. Too bad he also annoys the hell out of the monks.
* ''WesternAnimation/JackieChanAdventures'' ultimately subverts this. When the Tiger Talisman splits Jackie into two sides, Jackie's light side certainly seems like this at first, considering his even more extreme aversion to violence than normal, being reduced to crying in guilt after stepping on a bug, and [[ApologizesALot apologizing even more than usual]]. However, once he's finally convinced that fighting is, in fact, necessary, he'll hand out a beatdown just as effectively as his dark side, even if he does still apologize afterward. Amusingly, it's arguable that his dark half is actually the less effective one, considering his impulsiveness, overconfidence, and how his BloodKnight nature makes him easy to manipulate.
* In one episode of the ''Series/MorkAndMindy'' animated cartoon. You know the drill.
* Played with in ''WesternAnimation/TheRenAndStimpyShow''. Ren's two halves were evil and ''apathetic''.
* Done in Disney's ''WesternAnimation/AladdinTheSeries'', but not with the main characters. Instead, they go to China and meet two identical twins, Zin and Zang, one evil and aggressive and the other good and meek. The twist is that neither has actual power until they merge into a dragon, and the alignment of the dragon depends on who forces the merge. When the evil one causes it, the dragon rampages and burns villages. When the good one finally grows a spine and takes control (which frightens the evil one for some reason), the dragon fixes everything.
* Played with in ''WesternAnimation/JohnnyBravo'' when the villain of a Franchise/StarTrek episode challenges Johnny to a battle between good and evil. He is assisted by two intimidating mooks, while Johnny is paired off with a choir boy who immediately runs away. Johnny still wins however, because the mooks are dumber than he is, and the villain is a [[SissyVillain wimpy]] geek who can't even slap him without hurting his wrist. What makes this weirder is that this episode happened after Johnny was turned into a bumbling idiot who screams like a girl and is beaten up by little boys on a regular basis.
* Done in an episode of ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'' where Po, in his usual shenanigans, splits himself into his Yin and Yang half after glimpsing into the Mystical Mirror of Ying and Yang. While Bad Poe was ruthless, powerful, and even cunning (as when he sneaked up and imprisoned Shifu during his monologues where he realized Po's bizarre behavior was the result of the mirror), Good Po was overly flattering, nonviolent, extremely gullible (Bad Poe tricked him into trapping himself into a pillory just by asking him nicely) and even a little dumb (he thought he couldn't escape even though the keys Bad Po dropped were right in front of his feet and the pillory wasn't even locked in the first place as Good Po demonstrated when he retrieved them). Subverted in the end where Good Po intentionally undergoes multiple AmusingInjuries to weaken Bad Po so that the Furious Five will be able to make him gaze into the mirror again and reunite the two halves (since both Pos share each others' pain), then tricking him into destroying a replica while thrusting the real mirror into his face, regaining his old self.
* It's implied that this is the reason why Ron is a BumblingSidekick in ''WesternAnimation/KimPossible''. The few times he's hit with a MirrorMoralityMachine, he becomes focused and dangerously competent. So competent that the [[RoguesGallery established bad guys]] who encounter him, respect him.
** Also comes up in an episode where one of the aforementioned {{Mirror Morality Machine}}s starts being used randomly on a superhero team, causing the good and evil members to fight each other. For some reason, whenever one of the heroes is returned to being good, they immediately either start losing or try to run away.

[[folder:Real Life]]
* Jainist monks in India don't wear clothes (so they can't crush insects in them), sweep the ground they're walking on (so they can't tread on bugs), and sometimes even wear a cloth before the mouth, so they can't suck in flies.
** While less extremely ascetic, some Buddhist monks are also very careful to avoid harming even the smallest creature, carrying bells to warn insects and the like of their approach.
* The Talmud teaches that without the "evil impulse", mankind would spend all of its time praying and studying God's Torah. [[BalanceBetweenGoodAndEvil Evil is therefore necessary, even good to a certain extent]], because it makes people do good things like marry, build houses, and start businesses, which are all good because God wants human beings to create things on Earth.
* This is something scorned in Islam. It's not enough to claim to be faithful: God shall test His servants. The test can come in many form: hunger, poverty, ''war''... This is one of the reasons why Sufism (and the ''[[PerpetualPoverty zuhud]]'' life-style) is derided. A Muslim can't simply lock himself in his home and spend all his time praying that God will solve all his problems. Amongst the very first verses of Literature/TheQuran is about ''not'' wrapping yourself in SecurityBlanket (in Muhammad's case, he was cowering in fear after the first visitation by Gabriel).
* The [[TheFederation United Nations]] is almost universally recognized as an organization with [[WideEyedIdealist noble aims]], but is often criticized for being unable to get anything of substance done.
* In some schools of revolutionary thought, it is argued that peaceful protest held up as a strict moral principle rather than acknowledged as a strategy actually doesn't achieve very much at all and leads to few (if any) of the protest's goals being fulfilled. [[RuleOfCautiousEditingJudgement That's all that will be said]].
