Morality Kitchen Sink

""Among the Alps and Pyrenees, perhaps, there were no mixed characters. There, such as were not as spotless as an angel might have the dispositions of a fiend. But in England it was not so; among the English, she believed, in their hearts and habits, there was a general though unequal mixture of good and bad. Upon this conviction, she would not be surprised if even in Henry and Eleanor Tilney, some slight imperfection might hereafter appear; and upon this conviction she need not fear to acknowledge some actual specks in the character of their father, who, though cleared from the grossly injurious suspicions which she must ever blush to have entertained, she did believe, upon serious consideration, to be not perfectly amiable.""

- Jane Austen, Northanger Abbey

In some stories, the good guys are squeaky embodiments of shiny goodness and fight bearded stage magicians who cackle a lot. Then again, sometimes you have stories where your caped crusaders largely go up against the misguided and distraught. Other stories might have the pragmatic freedom fighters against a government who alternately sing orphans to sleep or murder their kittens. Still other stories have the world's mightiest, most murderous, most-pants-wettingest "heroes" you've ever seen against a guy who made entire worlds into slave-states for profit and kicks.

Then you have stories like this.

Rather than discrete groups or distinct moral systems, you have a sliding scale, and all groups and characters fall somewhere between "Hero" or "Good" at the furthest extreme and "Villain" or "Evil" at the other extreme. In most cases, the people closest toward the "Hero" end of the scale will be the main characters, but they're usually not perfect (and they can become even less perfect as time goes on). Their opponents fall further toward the "Villain" end of the scale, more often than not, with some that are so close to the Villain end that they don't really have any heroic qualities.

In short, none of the groups fit cleanly into the White-Gray-Black categorization, as all of them do things both good and evil with varying degrees of frequency. This generally makes for more dynamic stories, as you're never sure if the heroes will stay on the straight and narrow or villains will keep wreaking havoc.

Probably the closest to Real Life that any Morality Trope can be.

See also Shades of Conflict, Sliding Scale of Anti-Heroes and Sliding Scale of Anti-Villains. When you've got a specific group to which this trope applies, you've got a Four Philosophy Ensemble. Compare The Good, The Bad, And The Evil along with White and Grey Morality. Contrast Black and Black Morality, where nothing is good or morally ambiguous about the characters. Also contrast White and White Morality where nobody is truly evil.

Anime and Manga

 * Dragonball where many of the protagonists are former villains who change sides after meeting Goku.
 * Fullmetal Alchemist - The Elric brothers and Winry are the most purely heroic characters; the heroes from the State Military are more gray, being former war criminals who want to atone for their sins; Greed and Scar are fairly sympathetic antagonists ; there's Barry the Chopper who is the Token Evil Teammate for the State Military heroes- he's clearly Evil; finally, the other villain characters are definitely very far down toward the evil extreme of the scale. Then of course we get Kimblee.
 * Despite being the protagonists of the show (as well as priestesses), the Sybillae of Simoun have moralities that are all over the range. On one end, you have the innocent Rimone/Limone, Yun, and Morinas. Then there are the more ambiguous Paraietta, Mamiina, and Dominura. The nations of Argentum and Plumbum are a little harder to place, while the Defense Minister of Simulacrum is decidedly at the bottom of the proverbial drain.
 * The manga version of Chrono Crusade. Azmaria, Mary Magdalene and most of the members of the Magdalene Order are clearly heroes. Rosette's very heroic, but has a number of vices and character flaws that get the best of her; Chrono is kind and gentle but has a dark past (including formerly being one of the villains); and Satella is mostly concerned with her own goals but still shows empathy towards others. The Sinners, although being the main villains, are mostly in the gray, from Joshua (who is devoted to Aion because the demon horns on his head are making him lose his mind, but who has understandable and occasionally noble motives) to Shader (who hates violence and expresses remorse for her actions but goes along with Aion because she believes in his ideals) to Aion himself, who is a Well-Intentioned Extremist. The closest to the actual "villain" scale are the other demons, who are either beasts who take pleasure in attacking humans or soldiers sent to kill the Sinners and whoever gets in their way--but some of these are somewhat sympathetic, since many of them are simply . The morality structure is explained by the mangaka as being inspired by the idea that people aren't born evil, but become evil through their selfishness.
 * Code Geass. There is one genuinely, unquestionably good person, Euphemia, (Shirley is debatable, because while she is certainly kind-hearted and sweet, she is only concerned about her own feelings and school life while all hell is breaking loose outside, so she can come across as somewhat self-centred). There is one genuinely, unquestionably evil person, Luciano Bradley. Every other character's alignment can be debated. The main character himself can be convincingly argued to fall under any morality alignment.
 * Karakuridouji Ultimo. Naturally, as it's a series about the different kinds of good and evil.
 * One Piece is a HUGE example of this. The protagonists are morally ambiguous pirates that are motivated by self-interest and personal goals rather than any abstract moral considerations, but tend to do good anyway by defeating more evil pirates (or marines) that happened to do something to offend them. Other pirates can be anything from Chaotic Good adventurers to Selfish Evil jerkasses to Complete Monsters. Likewise Marines can be anything from legitimate heroes to guys who just want a check to well-meaning extremists to Knight Templars. One Piece characters have all kinds of varying motivations and alignments - it very much depends on the individual person rather than what group they belong to, which is quite realistic.

Literature

 * 1632: The heroes range from almost pure heroism to rather questionable, the antagonists range from Complete Monster to people who could be heroic under slightly different circumstances and/or are just victims of Values Dissonance.
 * In Chung Kuo, there are some very upstanding characters on both sides, who rub shoulders with pure villains.
 * Brandon Sanderson's Elantris. Furthest toward the Hero end, you have Sarene, who's upstanding but can be a little deceptive. A little further away from the Hero end, you've got Raoden, who resorts to some practical tactics. On a good deal toward the Villain side, you have Hrathen, but he shifts further toward Hero before the story is done with. All the way down at the Villain end, you have.
 * One of the best examples of this trope is The Dresden Files. At the furthest extreme of the Hero end we have Michael Carpenter, the Fist of God, who only fights monsters, has a grand total of one recorded instance of swearing in the series proper, and is all around about as wholesome as a person can be. Slightly away from the good extreme would be the majority of the series other heroes e.g. Harry Dresden, he's a generally upstanding guy with a MASSIVE case of Chronic Hero Syndrome, but isn't above a bit of pragmatism if it's necessary. More towards the middle of the scale is The White Council which is made up of plenty of Knight Templar Jerkasses but has methods which are shown to oftentimes be necessary. The main representative of dark gray is John Marcone, who is a ruthless crime boss, but ends up joining forces with Dresden more often than opposing him and WILL NOT tolerate any violence against children. As for the CompleteMonsters of the setting we have pretty much any one the supernatural villains, e.g. the skinwalker whose true form's mere sight is enough to send harry into a Heroic BSOD. To Top it of we even have Blue and Orange Morality in the form of the fae.
 * Daniel Suarez' Daemon and its sequel FreedomTM. Apart from Roy Merritt, who earns immortalisation as a genuine embodiment of justice, the reader's perceptions of who the good guys and bad guys are is constantly changing.
 * The Chathrand Voyages. There's so many plots and counter-plots going on that this is bound to happen. The three heroes need to constantly reassess who they can trust depending on which evil plot they're fighting at the moment.
 * The Aesop of Jane Austen's Northanger Abbey.
 * In David Weber and Linda Evans' Hells Gate series both Sharonans and Aracans are a hodgepodge of good, bad and in between, although Sharona does generally come off as A Lighter Shade of Gray.
 * Present in Madeleine L'Engle's A House Like a Lotus, with the addition that even one person is never completely good or evil. It basically boils down to "people are complicated."
 * Given that A Song of Ice and Fire has Loads and Loads of Characters and no clear heroes or villains, it's no surprise that the morality spectrum comes in about a thousand shades of gray. You've got extremely honorable, well-meaning people like Ned Stark and Brienne of Tarth, Complete Monsters like Gregor Clegane and Ramsay Bolton, and more Anti-Heroes and Anti-Villains than can be listed. Among the "anti-"s, fans can't even agree which ones of them are anti-heroes and which are anti-villains. It's largely a matter of perspective.

Live Action TV

 * Deadwood uses this to some extent; much of the early part of Season one casts the character of Al Swearengen as the most morally corrupt character in town. That is, of course, until Cy Toliver shows up, who quickly quickly steals the spotlight as villain most evil. Al is made to look almost a hero as the result. This is possibly subverted however, as the show in general uses the morality kitchen sink, and both Cy and Al do indulge in purely "good" acts on occasion.

Tabletop Games

 * While all Table Top Role Playing Games allow you to make a character who is anywhere on the map, different games have within their "default" tone different views. Please consider a game's "normal" tone and not what players might decide to do. For example, you could play a completely virtuous character in Shadowrun, but that doesn't change the fact that it's a dark and grimy cyberpunk world where amoral mercenaries work for backstabbing corporations and inhuman spirits.
 * Dungeons and Dragons and spin-off Pathfinder in most of its settings has this. There may be a necromancer who is repeating Mengele's work on his victims, a paladin who spends all his days feeding the poor and treating the sick when not rushing off to battle nasties like the necromancer, amoral thieves who just look to make a quick coin clipping purses in the market, well-meaning but ruthless knights who seek to put down the aforementioned thieves without realizing their oppressive lords have beggared the people, and a cult to a god of chaos and magic whose followers Blue and Orange Morality pushes them to do things no one understands. Really, the limitation is the player's and GM's imagination and their willingness (or not) to have certain things in their game. They may even be in the same Adventure Town. Newer, more "mature" games often aim at the more limiting Gray and Gray or Gray and Black morality.
 * Planescape may most exemplify this. You could literally be a divine servant from a fantasy version of Dante's Purgatorio, a Snark Knight anti-hero out of fantasy Charles Dickens, or a Complete Monster from a Milton-like hell. The various groups in the game are all over the map on their ethical stance.
 * While most of the Old World of Darkness has Black and Gray Morality, Changeling: The Dreaming and Mage: The Ascension follow this trope.
 * Most Changelings are Seelie dominant and generally good, but not necessarily supremely virtuous. Most Unseelie fae are still decent folks. Some Seelie and a few Unseelie are so old-school knightly they might as well be D&D paladins. Seelie and Unseelie villains alike range from operatic Harmless Villain to ruthless Pragmatic Villainy to cannibalistic Blood Knights to Eldritch Abomination-worshiping Complete Monsters.
 * Mages as individuals are usually trying to achieve good ends. The main conflict is Romanticism Versus Enlightenment, with the Romantic Traditions embracing old school mysticism and trying to awaken humanity and the Enlightened Technocratic Union trying to empower humanity For Science!. Then there are the Eldritch Abomination-serving Nephandi and the insane-as-all-Hell Reality Warper Marauders. The conflict started with the Traditions clearly being morally superior to the Technocrats, but the Technocracy got a little Character Development later on and it became very hard to say either side was right.

Video Games

 * A common part of Fire Emblem.
 * The Elder Scrolls - There are no morality bars. In Oblivion there was a fame-infamy bar, but the two don't always sync up. Therefore, the choices of the player determine where on the scale the protagonist falls, and it could be absolutely anywhere, embodiment of Incorruptible Pure Pureness Knight in Shining Armor to Complete Monster and anything in between. The NPCs, being pre-written, are also suitably vague and varied.
 * Because it's a game by Obsidian (formerly Black Isle), it should come as no surprise that Knights of the Old Republic 2 features this trope pretty significantly. If the player should choose to be Light Side, then s/he and his/her group are fairly close to the Hero extreme. A little further away from the good end, but hard to say by how much, would be the Jedi Council, who are shown to have good intentions but be seriously flawed in their execution of them. Further toward the Villain side, you would have Darth Traya. Then, practically sitting on the Villain extreme, you have Darth Sion and Darth Nihilus, with the second one the most non-Heroic, most Villainous person in the game.
 * Kingdom Hearts, particularly in its later instalments, is surprisingly dependent on this trope for a Disney property. Sora's pretty close to the hero extreme (though he's more personally-motivated than he seems), while the Disney villains actually come from 'verses with Black and White Morality. The grey areas range from Roxas (whose lack of memories sometimes leads to a sense of Ambiguous Innocence) and Riku and Axel (who are so devoted to their friends that they'll shoot whatever dogs are necessary to save them) to DiZ (who works for the same end as the good guys out of a need for revenge) and Organization XIII (which, in itself, has everything from the apathetic Demyx to the Evil Overlord Xemnas).
 * While the first Mass Effect had this to an extent, the second game features it a lot.
 * Furthest toward the hero end, we have Paragon Shepherd. There's also Legion, who is... strange, to say the least, but seems to be Lawful Good, and Jacob, who seems to be a good man who's just involved with bad people.
 * In the middle, we have Miranda (who has her moments), Garrus (who is a decent person but rather doesn't like criminals and ), Mordin (who will happily do bad things to stop even worse things happening), Samara who lives by a mostly good code of ethics but follows it quite closely, and Thane, who is a kind-hearted assassin who only kills bad people.
 * On down toward the villain end, you have Zaeed, a rather unpleasant mercenary with no empathy, Jack the convict and Grunt the violent krogan super soldier. Renegade Shepard also fits in here.
 * Even closer to the far end, you have the surprisingly charming Illusive Man, and.
 * Don't forget the Blue and Orange Morality of different cultures, most obviously the geth. For this reason,  has one of the most contentious choices in the game.
 * The Geneforge series. There are anywhere from two to five factions the player can join in each game. With the possible exception of 2's Barzites and 5's Taygen, they pretty much all have arguments in their favor. While the world itself is more about Gray and Grey Morality, the individual sides play out this trope. The Well-Intentioned Extremist tends to be the most common type in each, but they all have their share of saints and monsters, and everything in between.
 * Dragon Age Origins has shades of this. The only wholly villainous faction are the Darkspawn and even they become more sympathetic in Awakening. Dragon Age II takes it even further to the point that there is no Big Bad responsible for everything going wrong. Every major faction in the game is sympathetic to some degree and all of them are partially responsible for the Downer Ending. The games do have a few truly heroic and truly monstrous people, but they have surprisingly little impact on the setting as a whole
 * Star Warsthe Old Republic is shaping up to be an example of this. From what we know so far, it's just as possible to play a Light sided Sith as it is to play a dark sided Jedi, and a number of characters on both sides are morally grey.
 * However, let it be known that "Light Side" and "Dark Side" are very different concepts for Imperial characters and Republic characters. At worst, a dark sided Republic character will be a Token Evil Teammate, generally they'll be AntiHeroes. On the other side, Light sided Imperials are generally AntiVillains of various degrees, with the best being Type IVs, devoid of villainous actions, but still on the "bad side."
 * Blaz Blue Continuum Shift has changed the tone of the Blaz Blue series so now it's shaping up to be this rather than Black and Gray Morality.
 * On top of the chain you have the utterly innocent Noel Vermillion that just tried so hard to be 'good'. but just came off as some Wide Eyed Idealist. Following that there's both Jubei and Rachel Alucard, the closest we can get for Big Good, but tempered with how 'not-to-the-point' they are. Below them are Bang Shishigami and Taokaka, despite their apparent idiocy, they always fight for the good cause. The same to Platinum the Trinity (except replace idiocy with Split Personality problem)
 * Below that rank are some more sympathetic Anti-Villain and some lightly tempered heroes. Makoto Nanaya came closest to the top chain, but was highly tempered with her overprotectiveness to both her friends that anyone looking at them funny, she'd kill them flat. Then there's Hakumen, who works for his own code of justice, but goes extremely Knight Templar and believes this world is rotten and the only way to save it is to cleanse everything and restart it anew. Carl Clover used to be lower than this, killing things for his own gain while tampered with that he's opposing the one on the bottom of the chain, but due to Character Development, he moved up here. Iron Tager is a pretty decent guy, tampered with the fact that he's programmed to be loyal to Kokonoe at all cost. Even some of the Anti-Villain come off like this: Litchi Faye-Ling is a blatantly Type IV AntiVillain, a kind hearted woman who's in NOL because she's Forced Into Evil unless she wants to rot. Tsubaki Yayoi was Brainwashed and Crazy, but outing that, she always is a purdy girl who always wanted the best for everyone and came off really conflicted with her battle with her own demons.
 * And below that are the middle point... where some of the heroes reside. Ragna the Bloodedge, our hero, is a Jerk With a Heart of Gold at best, but his one-man crusade against NOL wasn't for altruistic means and only because someone pissed him off big time. Jin Kisaragi used to be lower than this, but after Character Development, he's stuck here rather than higher since he still is an utter Jerkass to many, and like Ragna, fights for himself. Also here is Nu-13, who is unconcerned with anything else except Ragna... and would kill anyone who gets in her way between her and Ragna. Arakune could fall either here or below as he's acting like a mindless beast that can only think of how to eat, and his human self Lotte Carmine is just a self-serving glory hound who only thinks of himself.
 * And below them are the head honchos of both factions: Kokonoe of Sector Seven and Imperator of NOL. Kokonoe is fighting against Terumi, but her methods were extremely brutal and she doesn't take someone else killing Terumi well, she had to be the one to frag him, even if it involves nuclear catasthrope, making her look even worse than some villains despite being on the side of Good. The Imperator of NOL implemented a tyrannical world-class order, only to prevent the world from decaying into utter anarchy, but might've gone a little bit too far and not realize that the organization is being manipulated by the worst of the worst below...
 * The bottom of the barrel, the blackest of black morality can get is inhabited by both Terumi Yuuki and Relius Clover. Relius is a Mad Scientist with Lack of Empathy that does every mad experiments gleefully For Science!, while Terumi is does everything bad in this world for his own amusement, and is utterly gleeful in taunting on his victims' misery just because. Some scenes in EXTEND made Relius in a grayer shade than Terumi that he might have some pragmatism in his brutality, rather than Terumi who does things For the Evulz and himself, but not enough to make him escape the term Complete Monster.

Web Comics

 * Comes with the the territory of being based on the Dungeons and Dragons alignment system in the Order of the Stick. You have good characters doing good things because it's the right thing to do, bad people doing bad things for a greater good, and bad people doing bad things for amusement.
 * Errant Story. Oh, my, yes, Errant Story.
 * Sinfest. Satan is definitely evil, if affably so. God isn't evil but definitely a jerk, his son however is definitely good, the Dragon neutral and Buddha somewhre technically neutral but nice. The mortals are all over the place.

Web Original

 * There Will Be Brawl uses this a lot. Farthest towards the "Hero" side would be Luigi and Red, who genuinely want the best for the Mushroom Kingdom and its inhabitants, and work to solve the mysteries in the show without resorting to more extreme methods like Mario or Link. Characters closer to the "Villain" side are people like Wario, who's only out for his own self-interests, then  who forcibly attempts to usurp the Kingdom's power, and finally Kirby at the most extreme, who just likes killing people and sowing fear among the populace.
 * The Whateley Universe does this in spades. Start with the heroes of Team Kimba. They range from the 'I don't even want to hit people' attitude of Phase to the 'I had to slaughter a hundred bad guys to rescue people' switch of Tennyo to Bladedancer, who killed an ordinary family man in cold blood to prevent a possible Bad Future. The villains are all over the place too. Supervillain Dr. Diabolik is apparently a great father, and his children have said he only does the things he does to advance mankind.

Western Animation

 * Avatar: The Last Airbender fits. Most of Team Aang is unequivocally good and the most powerful members of the Fire Nation are power-hungry sociopaths, but almost everyone else falls somewhere in between.  turns out to be a Crap Saccharine World, and the Northern Water Tribe has some pretty sexist moments. The rank-and-file and civilians of the Fire Nation are more often misguided patriots than outright evil. You could make a decent argument that the whole series is a subversion of the Always Chaotic Evil trope.
