Please read the instructions / trope description on the main page before posting.
Raoh of Fist of the North Star is an Evil Overlord who believes peace through tyranny and had clashed with his brothers more than once. However he despises torture and at one point, slaps the head off of a rapist in his army who thought he was dead. In the manga, he even hated what his even older brother Kaioh has become, and requests Kenshiro to defeat him if he's defeated himself.
Vampire Game: the heroine's aunt Ramia may be an Alpha Bitch who mistreats her sons and favors one over the other, but when a vampire suggests that she kill her adopted son's mother, who is a prostitute and whom Ramia strongly dislikes, she responds by saying that even though she doesn't like the woman, she's still a citizen of this country, and she's obligated to protect her. She then tells the vampire to beat it. She also cannot stand their uncle's misdeeds.
In the second season of Space Battleship Yamato, the evil emperor-without-an-empire Dessler discovers that the court intrigues of his allies on the White Comet transgress even his moral limits. Particularly when he winds up in their prison cell.
in Space Battleship Yamato 2199, Wolf Frakken is troubled by the abuse suffered by a Zaltzi soldier at the hands of a cruel and racist warden of a prison planet. He holds one of his crew back from interfering, but is moments away from belting the warden himself before Yuki Mori intervenes.
Light also keeps his family safe and refuses to write their names into the Death Note, particularly his father's, though he does wonder if writing his sister's might be necessary at one point... but is still disgusted when he finds out that Mello kidnapped her, thinking he was going over the line. However, when his father offers himself to take the Shinigami eyes deal in order to take down Mello, Light doesn't try to stop him, though he originally wanted Matsuda to take the deal. This indicates that while he did care about the safety of his family, he was more concerned about disposing of his enemies.
Initially, he states that if he were Kira (and the audience knows he is), that Kira wouldn't kill people that had killed for survival or self-defense reasons, or people that had been convicted of (usually petty) crimes but had since served their sentences and made a commitment to being functional, law-abiding citizens. And he usually saved his (not-so)"divine retribution" for people that had been convicted of major crimes like rape or murder...though not always. (On the other hand, he's not above killing people who had been exonerated, or found to be not guilty in a court of law due to lack of evidence, or people that were facing charges but had yet to be convicted.) However, by the end, whatever standards he had went out the window.
In the Mello/Near arc, he makes it obvious that he's not too thrilled with Demegawa, who was hosting a "pro-Kira" show, suddenly turned his mind to the money he could make. Though this has less to do with his greed and more of the fact that Demegawa could potentially ruin a chance to make people support him even more.
In Black Cat, Train Heartnet, a professional assassin who has killed plenty of people, will NOT kill women or children. Once he was going to kill his target and then he noticed that his intended victim was holding a young child, and he hesitated and couldn't pull the trigger, which led to him getting shot. Considering he reforms later on in the series, this, along with Saya's death at the hands of his partner Creed is probably what caused him to give it up.
In Detective Conan, although the mysterious and beautiful criminal Vermouth has killed many people, she will not kill the protagonist, or his love interest; this probably has to do with the fact that they saved her life a year ago, and Conan is the son of Vermouth's friend Yukiko Kudo. Things get really interesting when Ran sneaks in the trunk of Jodie's car and tries to stop Vermouth; her mook immediately starts shooting, but Vermouth yells at him and tells him to stop shooting. As Ran protects Haibara, (whom Vermouth hates), Vermouth shoots around her, and tries to get her to release Haibara.
Among the first things Legato Bluesummers does in Trigun is wipe out a group of slave traders. While he is an Omnicidal Maniac, he then goes up to their "merchandise" and tells them to make the most of their lives (because they're going to be short if he has any say in it).
This has a lot to do with Legato's undisclosed-in-the-anime past. He was a former Sex Slave, so although he hates humanity in general, he hates slave traders most of all.
In Pokémon, although they're not evil, Jessie and James are Team Rocket agents - kidnapping Pokémon is part of their MO. They do not believe in trainers hurting Pokémon, however, and this is why they (and Meowth) were appalled by Paul's method of training.
"Team Rocket may be rotten cheaters, but we're not in the business of destroying children's dreams!"note "At least, not yet."
This also shows in how they treat their own Pokemon with a great deal of care. They also have been shown to be disgusted by more brutal Pokemon Poachers and trainers and haven't been shown being brutal or overly mean to their captives, unlike some other more evil Team Rocket members shown in the series. (Though the captives's trainers are "fairer" game, as once in Advance Generation they almost kill Ash.)
In one of the most heartwarming/tearjerking episodes of the series, "A Poached Ego!" includes the trio finding a group of poached Ekans and Koffing, the pre-evolved forms of Jesse and James' longtime main Pokémon pals, Arbok and Weezing respectively. A bit later into the episode, they run into their poacher, Rico, who uses Pupitar to fend off the Rocket trio after denying to give them their evolved forms of the Pokémon, which would've given him a financial bonus. With obvious incentive, they fight hard for the Ekans' and Koffing's freedom. Eventually they come at a point where they are unbalanced against Rico's powerful newly-evolved Tyranitar and its constant Hyper Beams. Having freed the poached Pokémon prior, and nothing left to defend themselves with, they ordered Arbok and Weezing (who have been with their partners since their childhood, and were birthday and Christmas gifts, respectively) to escape to safety to take care of their kind. The trio even continued to fight the Tyranitar by themselves, even Jesse and James to the best of their ability. The size of the sacrifice just goes to show that they truly wanted what was best for them, even if it meant enduring both substantial emotional and physical pain.
In "The Stun Spore Detour" after Misty helped James and Meowth heal Jessie's paralysis from the Vileplume's fumes, the female team rocket member still wanted to try and capture Ash's pokemon thinking he and his friends would still be weak from trying to recover from their own wounds. James and Meowth refused to help, Meowth even looking physically sickened by Jessie's coldness, and when she got knocked out by her own pokemon, they chastised her for being ungrateful.
In Pokémon 4Ever: Celebi: Voice of the Forest: Jessie, James, and Meowth initially accompany the Iron-Masked Marauder to catch Celebi (out of hero worship initially, but very quickly fear of him). However, they're genuinely horrified of the Marauder's methods in doing so (I.E. brutally electrocuting Celebi, and brainwashing it into destroying the forest). The trio may love stealing Pokemon, but they would never sadistically torture and manipulate them.
Jessie is also horrified when the Marauder tells her that he plans to use Celebi to overthrow Giovanni & rule Team Rocket
Paul himself has several, while it is true that he releases his Pokemon after they're no longer useful to him or failed him. He is at least upfront about his harsh training, compared to the other abusive trainers in the past such as Damian (Charmander's previous trainer). Upfront to Pokemon, that is. While Damian lied to Charmander that he'd come back, he had no problem telling people how he feels about "useless" Pokemon.
Paul was also loudly against the Sunyshore gym's then current policy of just handing out a badge to anyone who came to the door. Jerk or not, Paul definitely doesn't cheat his way to his goal.
Slayers Next. Gaav concentrates all his resources on trying to kill Lina, because he believes his archenemy Hellmaster Fibrizo will use her to destroy him. However when confronting Lina he still gives her the chance to fight back; and when she casts the Ragna Blade and Gaav knows the spell could kill him, he still gives her the chance to attack first and doesn't try to pull any dirty tricks. Ultimately this leads to his demise; although the Ragna Blade doesn't kill him it weakens him enough for Fibrizo to step in and destroy him.
Omnipresent throughout Mobile Suit Gundam. Even many Mooks draw the line at killing women or children, and Ramba Ral dies as a result of such morality. The most obvious use is in the case of Gihren Zabi, an individual so vile that many of his mass-murdering allies find him disturbing. His father, himself a fascist dictator who likely murdered his predecessor in order to gain power, compares the man to Hitler unfavorably. And his sister, who's spent her time establishing her uberbitch credentials, hates him so much that she ends up killing the man for ordering patricide.
Also, in Mobile Suit Zeta Gundam the Titans are a brutal elite force that fights the AEUG and commits lots of atrocities while at it, but many of its members are repulsed when it comes to gassing entire colonies. In fact, the Face–Heel TurnReccoa killed The Dragon for having sent her in a mission that, well, had her gassing a colony.
In Mobile Suit Gundam Wing, OZ leader and Magnificent Bastard Treize Khushrenada was vehemently opposed to the Romefeller Foundation's Mobile Doll System, feeling that they would make humans unnecessary for battle. As a result, he resigned as Chairman of Romefeller, and OZ soldiers loyal to Treize split off to form the Treize Faction.
In episode 13, two of Noin's former students are pretty ruthless when they attack remnant forces of the Alliance, and refuse to accept surrenders even when they're offered. When Zechs joins with them in a later attack, he orders the Alliance forces to surrender, and is appalled that the two OZ troops are still attacking surrendering troops. One of them is killed by the Alliance who feels Zechs betrayed his word in a last ditch attack. The other one starts attacking Zechs partly out of vengeance for his friend, and partly because he felt Zechs was too lenient on the enemy forces. Zechs ends up destroying the other OZ trooper's mobile suit as a result.
In Mobile Suit Gundam SEED, the people inside Jachin Due are shocked when they hear Patrick Zala give the order to aim GENESIS at the Earth. One aide, Ray Yuuki, tells him that it would kill half of Earth's population and destroy the surface; Patrick shoots him. When another aide warns him that the other ZAFT soldiers are in the line of fire, Patrick tells them it's for their victory and that the Naturals must be eradicated. Ray uses the last of his life to shoot Patrick.
Marida Cruz from Mobile Suit Gundam Unicorn is a Tyke Bomb and former Child Soldier, but draws the line at killing non-combatants. During the first episode, she revives a group of workers she had knocked out during her pursuit of Princess Mineva, and later saves the life of one her captors after a hole is blown in the side of the Nahel Argama. She's even shown to be distraught upon seeing that her attack on Industrial 7 has resulted in civilian casualties.
Ulquiorra is willing to psychologically and emotionally torture the captive Orihime, but when Nnoitra suggests he's also in a position to molest or rape her, Ulquiorra is disgusted.
Grimmjow's only interest is becoming strong enough to be the 'king' over everyone else. He doesn't even mourn his own subordinates after they die in battle. However, he believes in a fair fight enough to ensure Ichigo's injuries are healed before they fight to the death, and he insists on Orihime healing her own injuries before healing anyone else's.
In the OAV Riding Bean, Bean Bandit is a professional wheelman with a soft spot for kids. In Gunsmith Cats, nothing's changed. In one volume, Rally sees Bean, after delivering a package of drugs, stuff a drug dealer down a manhole for trying to sell drugs to kids. Rally challenges him to a race on the condition that if she wins, he'll give up doing drug-related jobs period. They finish in a draw, but evidently the Bean Bandit was so eager to give up dope-running that he concedes defeat.
Priscilla in Claymore. While she's ready to kill and eat men, women and boys, she doesn't kill girls. Because helpless girls remind her of her childhood trauma: when she was a child, she watched as her father was possessed by a monster and ate the guts of her mother and siblings right before her eyes, and while he chowed down on her sister, she snuck up behind him and cut off his head with a knife. No wonder she has issues.
Comedic Sociopathy is the norm in Ranma ˝. Yet even Nabiki, heartless enough to sell photos of Ranma's female side to hornball men as a supplement to her pocket money, and who went so far as to sorta whore him out during her stint as his fiancée, is disgusted when Genma reveals he regularly stole food from the juvenile Ranma. Akane Tendo, who has no qualms about beating her fiancé senseless when they fight, is horrified at the extents Shampoo is willing to go to in order to try and drive away her Stalker With a Crush, Mousse. And Genma, perhaps the one of the purest Jerkasses in the series, is disgusted by the antics of Panty Thief and Lovable Sex Maniac Happosai.
Phoenix King Saffron, a spoiled brat who mistreats his subjects and thinks nothing of kidnapping, killing, or blackmailing, tries to incinerate Ranma with one of his fireballs. Ranma tosses Akane's doll-like body note not really, it was just her clothes as a decoy, since it absorbs heat. Saffron is aghast and declares Ranma to be a wretched coward.
Ranma himself, who has been known to exploit his feminine side for free food, belittle his fiancée for her lack of feminine skills, and prance around nude in his girl form, using his lack of feminine modesty to distract opponents... has stated that he believes that the lowest of the low are men who come home drunk and beat their wives. And he himself is sometimes put off by how badly Shampoo treats Mousse.
In Yu-Gi-Oh!, when Pegasus notices Bandit Keith pulling cards from his wristband during his duel with Jounouchi (Joey in the dub), he waits for Jounouchi to win, then calls Keith out both on his cheating during the duel, and stealing Jounouchi's entry card to try and get him disqualified. Pegasus then has his security guards haul Keith away and congratulates Jounouchi on winning in spite of Keith's dirty tactics. In the manga, when Keith decides to threaten him for the prize, because he cheated/lost in a game, Pegasus is disgusted enough to kill him with a Penalty Game by turning Keith's hand into a gun and forcing him to commit suicide for his impudent actions, all the while making the most serious face he's made up til that point.
Speaking of Pegasus, we should keep in mind that Jounouichi, Honda (Tristan in the dub), Anzu (Téa in the dub), and Bakura were not invited to his tournament at all, and he could have had them all thrown off the island at any moment. Instead, he allowed them into his home and gave them rooms and food like the four finalists. Plus, Mai had previously been defeated and lost all her star chips to a Player Killer, and only got them back after Yugi beat him for her, so Pegasus could have easily had her disqualified as well. Aside from his plan to take the Millennium Puzzle (and even that may not count since it was only in the anime's dub), Pegasus was a remarkably good sport about things.
Played with in Battle City. Marik decides to cheat by using Rishid (Odion in the dub), who is posing as him, to use the (fake) Millennium Rod to "release" Bakura's good half, who is confused and wincing in pain from the stabbed arm Dark Bakura gave him prior, since Dark Yugi wouldn't be likely to attack his friend in that state. Dark Bakura subsequently betrays Marik, but he didn't do it because he had standards or because he cared about Bakura; he only did it because if Bakura was killed, he'd cease to exist. Though he DOES give Marik a look of disgust before he takes control over Bakura back, implying that this trope was a part of his motivations.
In a filler arc of the anime, Noah intervenes to stop Ooka (Johnson in the dub) from cheating with his duel with Jounouchi, irritated since he wants his cronies to best Seto and his friends fair and square. If it weren't for Jounouchi convincing him to let the duel continue, Noah was set to stop the duel since, by all accounts, Jounouchi would have won by then if Ooka hadn't cheated. (Unfortunately, Noah later proves little better than Ooka, and unlike Pegasus, there are very few mitigating factors to excuse such behavior.)
And in another anime filler, Raphael refuses to allow any of his monsters to remain in the graveyard, even sacrificing his own life points to return them. This is sympathetically explainedbecause he's an orphan who horribly lost his whole family.
In the original manga, Kaiba has this reaction when he sees Marik's duel arena for Yugi to fight the brainwashed Jounouchi — designed so that one of them will be killed in the end — believing that even at his worst (an Ax-CrazyJerk Ass who spent a fortune to build an amusement park with five levels of deadly devices and games, complete with an expert torturer, two ex-military specialists, a contract killer, and a serial killer, all in revenge for "the other Yugi" beating him at a Shadow Game of Duel Monsters…well, that and the Penalty Game he got as a result, which had haunted him in his nightmares since), he would not have stooped so low as to create a challenge with no other alternative. He later goes so far as to risk damaging one of his Blue-Eyes to stop it (he had hoped the card he'd draw would be a Common, when he sees what it is, he curses, but uses it anyway; note that in a previous chapter, he got very angry at a Mook for forcing him to ruin his copy of Gyakutenno Megami, after using it to jam a gun.)
In Yu-Gi-Oh! 5D's, Rex Godwin had nothing but disdain for Takasu, a prison warden who abused his power, framed the inmates for rules violations (among other abuses), cheated as a duelist, and was generally a disgusting person, and eventually fired him.note After he lost in a duel to Yusei, in spite of all the cheating and with Yusei playing with a deck literally scrapped together from cards given by fellow inmates.
In Yu-Gi-Oh! ZEXAL, Vector is more evil by far then the other six Barian Emperors, and none of them like him very much. (Alit, especially, seems to have nothing but contempt for him, and Durbe actually had to hold an angry Mizael back to prevent him from attacking Vector after he insulted the defeated Alit and Gilag.) In fact, Vector appears to be the only one who has actually been witnessed doing anything that could be truly considered "evil", other than fighting the good guys. (Gilag has Brainwashed a few people, but such victims don't seem to be permanently harmed by it.)
The German anti-robot KKK-expy in Pluto is nonetheless appalled by the murder of robot children, even though they don't look remotely human (or even cuddly).
The younger Toguro brother in YuYu Hakusho, while having sold his soul and became a contract killer, obeys a strict code of honor, almost never killing people unless it's specifically part of his current job, and displaying great dislike for those who commit dishonorable acts. When the older Toguro brother plays mind games during his fight with Kuwabara, the younger Toguro demands that his brother stop, and is pretty visibly pissed off. Also, when his same brother attempts to interrupt his one-on-one fight with Yusuke, little brother finally gets fed up with his elder and nearly annihilates him with a single punch. Toguro also killed the entire tournament committee because they tried to tip the scales of the Urameshi/Masho round in Team Masho's favor using their executive power. Seriously, do not act dishonorably in front of the younger Toguro.
Granted, elder Toguro was practically spitting on Genkai's name, who younger Toguro loved and killed the night before. It's possible he was still very bitter about the whole incident.
During the Urameshi/Masho round, Kurama passed out while standing after the second consecutive victory. Due to the aforementioned committee, he was forced to fight the third round while unconcious against Bakken. it went about as well as you think it would. The fight was in such bad taste, even the sadistic announcer tried to stop the fight numerous times just because Kurama wasn't conscious to "enjoy" the beating, too.
In Black Lagoon, you can throw a stone anywhere in Roanapur and you'll find that whoever it hits or lands near will have more standards than Chaka. Even the Neo-Nazis had more class than him.
Revy: Wow, this is surprising. You shot your own subordinates. Despicable to the end. (setting aside the fact that she herself has killed non-combatants on more than one occasion. Well, non-combatants that she had no attachment to.)
In Transformers Armada, when Starscream defects to the Autobots, Hot Shot points out that Sideways has already betrayed them. Starscream gets angry that they would compare him to that bastard.
In One Piece, Dragon-in-Chief Rob Lucci is an Arrogant Kung-Fu Guy, Psycho for Hire whose idea of a hostage rescue is "massacre everyone so they don't have to live with the shame." However, he is visibly disgusted when his far weaker boss Spandam beats Nico Robin while she is tied up, helpless, and unable to use her powers to fight back.
He also sneers at him when asked about why he didn't do anything about Chimney following them and finding the way to the gate, later telling Luffy how to get there as well. Whether that's because he dislikes Spandam or he simply doesn't wish to kill children is up to your interpretation, though.
While it makes sense that Lucci wouldn't be interested in killing a defenseless child, he refrained from stopping Chimney because he wanted Luffy to find him so they could fight. It's obvious that he dislikes Spandam either way, though.
CP9 as a whole (except Spandam) fits this considering their solidarity; after the World Government turns against them thanks to the Enies Lobby incident being pinned on them, they all try their hardest to raise the money necessary for Rob Lucci's medical treatment. They also show that they care for the land where they were born and raised, shown when they stand menacingly against an army of Marines that would have disturbed it.
Absalom, who is a huge pervert that has no qualms about engaging in sexual assault, likes weaker women who can't fight back, and stabs Sanji in the back during their fight, seems genuinely concerned with Perona's abuse of Bearsy.
Eustace Kidd is a sociopath with a HUGE body count on his head, killing people for being weaker than him, for belittling him in any way, or just For the Evulz. But slavery is something he would never involve himself in. Kidd's reasoning is At Least I Admit It: sure, he's done his share of killing and pillaging—but taking into account that he's a pirate, it's to be expected. The Marines and World Government, on the other hand, espouse "Justice" while allowing slave rings to operate unchecked, making them hypocrites on top of being evil.
Chief Jailer Shiryuu's bloody rampages across Impel Down have made Magellan, Impel Down's chief warden, very displeased, particularly as he had no damn reason for killing off prisoners, and he was forced to imprison him in Level Six as he was far too dangerous to be ignored. Given the fact that Impel Down is likely the worst prison in fiction where all the jailers are cruel sadists, Shiryuu's treatment of the inmates must have been horrid beyond belief.
Helmeppo has no morals about lying to prisoners, bullying townspeople, or throwing kids over the fence. Killing kids is another story and he's genuinely shocked when his father kills off an officer for disobeying a kid-slaying order. Probably why he gets a genuine Heel–Face Turn when he is pressganged into the Marines.
While Luffy is far from evil, he can be pretty chaotic as a pirate and does what he wants. During the Impel Down arc, he was willing to ally with several potentially dangerous criminals and former enemies in his quest to save Ace. However, he draws the line at freeing Crocodile, as even Luffy can't overlook what he's done. He's freed anyway.
Many other otherwise despicable pirates in the series have shown the slightest goodness in that they have that much care for their own crew, such as Blackbeard, Donquixote Doflamingo, and Bartolomeo (though considering the fact that he downright worships Luffy, it's sort of hard to see him as despicable). Heck, Bartolomeo takes it a step further by protecting Bellamy after one of his boss's underlings tried to have him killed, claiming that thanks to the fact that they had just fought in the same ring, they were Fire-Forged Friends. Buggy fits to a lesser extent; he only becomes A Father to His Men after Luffy defeats him, and he may be the least hardened villain in the series.
It was surprising when it was revealed that even Admiral Akainu had standards. He had clashed with Aokiji over who would become the next Fleet Admiral with the latter heavily opposing his ideals and promotion. Their conflict eventually led to them having a fight to the death to see who would become the Fleet Admiral. In the end, the former won but he decided to spare the latter. It was lampshaded that even Akainu couldn't face his previous ally without some sympathy. Although the case could be made that Admiral Aokiji had not commited a crime and that the fight was a duel, not a matter of justice.
When Sanji and Franky witness an example of You Have Failed Me from Rob Lucci, their reactions are this;
Sanji:These are the agents of justice...? Franky: They're more evil than we are.
The G-5 Marines are sick bastards who like to torture captured pirates just for fun. But when they encounter Trafalgar Law, who became one of the Seven Warlords of the Sea after sending the hearts of 100 pirates to the World Government (Given Law's power, there's no guaranteethat they're even dead), they got scared and called him "insane" and "a creep".
A better example is given at the end of that arc, after their Enemy Mine with the Straw Hats. They badmouth the Straw Hats as if they were the usual variety of pirates because if they don't, they'll admire them.
Later, Smoker and Tashigi are discussing cases of children being kidnapped in recent years. Tashigi thinks that someone in G-5 was involved in those cases, and tried to cover up for them by sending fake reports to the headquarters. When Smoker pointed out that this is what Tashigi meant, the G-5 Marines got pissed as soon as they heard that, saying that even though they are army rejects, they still have their pride as Marines.
Perhaps the biggest One Piece example of this trope (to this point) is the World Government's attitude toward WMD. Apparently, the same organization that invented the Buster Call and is responsible for multiple forms of genocide and other atrocities is somehow appalled at the usage of chemical warfare, such that they've deemed it illegal and attempted to imprison one of the leading researchers on it (and of it, considering his Devil Fruit), albeit after the latter created an "accident" at a research facility.
Trafalgar Law has a pretty nasty reputation as a pirate, but when Caesar Clown told him that he had drugged the children he kidnapped in order to prevent them from escaping, even he was disgusted. There's also the respect that he shows to Luffy, allegedly due to him being a Worthy Opponent. But in light of the Dressrosa arc, it's more likely because they both bear the name of D.
Subverted with Don Krieg; the main reason he stopped at the Baratie restaurant was not just so he could eat because he was starving, but because his crew was starving as well and he couldn't just stand by and let them starve…because he didn't want to lose the manpower at hand.
Diamante, one of the top executives of the Donquixote Pirates, beats the tar out of some Colosseum thugs who claimed Rebecca hadn't "really" won her block of the tournament and thus shouldn't be in the finals. This is the same Diamante who killed Rebecca's mother in cold blood ten years earlier.
Diamante's bos Doflamingo is a self-centered dick and easily among the nastiest of the Seven Warlords of the Sea, but he's not the type to start fights over dreams, and he even if he is, he'd make sure he didn't lose which is why he personally (well, almost personally) beat up and dismissed Bellamy.
When Doflamingo and his crew discovered that the aforementioned Trafalgar Law was from Flevance, a country no longer existing due a tragedy involving a susbtance called Amber Lead, he berates Jora for bringing it up, since it clearly disturbs that person. He along with his crew explain the truth about Flevance: Amber Lead was poisonous yet the World Government let them get rich from it before abandoning the country when everyone got sick, sending the population into wars out of desperation to escape and resources. Doflamingo is QUITE the bastard, but even he found the fate of Flevance to be an atrocity plus reading about it caused him to dwell on his own Dark and Troubled Past, causing him nightmares.
In the twelfth movie, Akainu found Z to be a bit extreme with his methods. Admiral (Ripper) Akainu, who as mentioned above (using his real name, Sakazuki) would sacrifice a thousand innocent people to potentially kill one criminal, and has done so before, thought he was extreme.
Which makes sense, considering that Z's plan involved turning the entire Grand Line into a fiery wasteland. While it would undoubtedly kill all pirates, the sheer amount of property damage and civilian casualties, plus the thousands of marines that would die in the crossfire, was too much, even for Akainu.
The Vinsmoke family are a group of ruthless assassins who easily sacrifice members of their clone army and will ruthlessly beat a young woman for serving food they don't like, but they're still visibly disturbed at Big Mom's collection of unusual humans and animals. Said collection is kept in books via an underlings Devil Fruit that keeps them from every dying and are held there by enormous pins.
For all his faults, even Akainu despises the fact that the Marines are essentially attack dogs for the World Nobles and calls out the Five Elder Stars for allowing Doflamingo to fake his resignation.
In Lupin III, the titular Lupin may be a thief but he's a Gentleman Thief, and he reminds anyone who asks that the people from whom he steals are people who can take the loss, and that there are worse people than he in this world. He also shows a chivalrous streak that compels him to help those less fortunate than he is (especially attractive women). Furthermore, Lupin often takes it upon himself and his gang to stop criminals engaged in more violent crimes and leave them for the Sympathetic Inspector Antagonist (Inspector Zenigata) to arrest. Regarding Zenigata or any other law figures who chase him, Lupin always seeks to elude, not to harm; he lives for the chase and actually prefers his pursuers left embarrassed but otherwise in one piece. One time in the second series, he tries to steal a very rare bottle of French wine but ends up accidentally stealing a load of Christmas toys. Zenigata starts railing at Lupin on television for that, but as soon as he realized the mistake, Lupin immediately airdropped the toys to the gathered children who were the intended recipients.
Note that this is the complete opposite of his original portrayal in the 60's manga, wherein Lupin was ruthless, murdered without a second thought, committed multiple rapes in front of the audience, lynched two police officers, and was generally far more cutthroat.
Aur the Villain Protagonist from Maou no Hajimekata, doing his part as Demon Lord, goes to a village and demands a virgin maiden as a tribute for him, the village chief offers him a little girl, Maria, Aur asks if they are trying to mess with him, the chief responds that all maidens were taken by bandits, royalty and the like so Maria was the only virgin left; Aur decides to take Maria anyway, reasoning she could of some use one day, unlike all other women Aur likes to have his way with it seems he pulls the break on little girls at least, treating Maria with some kindness even, like a mascot. Aur's servant Lilu however starts lecturing the innocent Maria on sex education so when she matures she can finally start servicing Aur.
Anti-Hero Fukunaga of Liar Game, despite perfectly willing to deceive and lie to others to benefit herself/himself, snapped on a teammate during the Musical Chair Game when he suggested that Nao should be the one to be degraded to the Gaya group (where she would have no chance in advancing to the next round), declaring that they shouldn't put that kind of pressure on Nao who isn't even the room at the moment. So naturally Akagi lampshades this.
Oddly enough, Solf J. Kimblee comes off as this in Fullmetal Alchemist. He's perfectly willing to let Pride kill Ed so long as he does it in a sufficiently dignified and awesome way. Kimblee comes to Ed's aid simply because he can't stand the idea of someone supposedly innately superior trying to save themselves by clinging desperately to an inferior's body and verbally bitch-smacks Pride before leaving the planet for good. Kimblee has a strict code by which he lives and judges others. This code has nothing to do with morality, but rather being true to one's convictions. To him, the lowest of the low are hypocrites.
In the anime, when Dante erases Gluttony's tattoo and turns him into a mindless eating machine, even Envy looks a bit horrified.
In G-Spot Express, Katsu beats up a gang of rapists when he sees them attacking Yumi (whom he just happened to have molested in the past himself). However, he also allows Ginji's crew to rape Sayaka after she arrests a friend of theirs.
In Umineko: When They Cry, the sadistic Beatrice takes young Maria Ushiromiyaunder her wing, because she's utterly disgusted by her mother's Rosa's abuse of her. This action is the downplayed variant of the trope, however, not stopping her from killing every other member of Maria's family in horrible, horrible ways - including the people in it who are actually nice to her... and more strangely, she also allows Maria to go Calling the Old Man Out to fatal levels, while commenting on how Rosa and Maria's relationship is sad and poisoned. Beatrice also really dislikes a witch that is worse than she is (Eva-Beatrice), and in the games she tells that to her very face, especially the horrible torture she inflicts on Maria and her mother, and winds up delivering a Mercy Kill to Maria to make her death quick.
D.Gray-Man: Wisely used an Exposition Beam to show another character Kanda's childhood memories.Allen is sickened and profoundly pissed off, and Kanda is in a Heroic B.S.O.D. state. Kanda. Even the local villainous Creepy Child Road, who delights in Mind Raping people, seems to be upset by it.
Towards the end of the Live-Action Adaptation of Death Note, Misa Amane, previously an amoral mass-murderer at worst and a Psychopathic Manchild at best, is genuinely shocked and starts to cry when Light writes his own father's name into the Death Note. Which is justified, since it comes from her being an orphan with serious issues about it and having that side of her being given much more attention than in other DN media.
In the manga and anime, during Light's first meeting with Ryuk, the latter is stunned by how many names Light has written into the Death Note in just five days. Protip: if your murderous rampage gives a god of death pause, you might want to scale back a little. Then again, this could also be understood as him being impressed, since he also tells Light that most gods of death are shirking their duties and that Light himself would make a pretty epic Shinigami. Double-subversion comes during the clip showing L's funeral. A montage of Light's killing spree is briefly interspersed with a single clip that strongly implies Ryuk was very strongly considering writing Light's name in his own Note. An interpretation being that even Ryuk, who set all of this in motion out of boredom, is surprised by the absolute craziness Light generates, another is that he may have been legitimately scared of Light killing him with a Gambit Roulette just like he did with Rem.
There's also Higuchi. His Evil Laugh scares Shinigami.
Despite all Light will do for his plans to succeed, he can't bring himself to write his sister's name in the Death Note. Though, that might have been partly motivated by how his plans would turn out if he did kill her.
Light is initially dismayed when Mikami's killing spree extends to even relatively innocent people guilty of such minor acts as being lazy, but later thinks to himself only that it's "too early to be making statements like that," suggesting he may agree. Explicit in the manga when he actually toys with this very idea early on in the story.
Rem has no qualms with Misa murdering innocent people, as well as murder being committed for her sake, but is repulsed by Higuchi's greedy and obsessive nature.
Could be argued of Stein to Medusa in Soul Eater, given their fight was on the basis of pitching two violent anarchists against one another to see whathappened. Stein is clearly attracted to Medusa's point of view (amongst other things) and claims that only fear of a higher authority (i.e Lord Death) holds him back. But when Medusa claims she is the mother of the child she's been experimenting on - Crona - and that she would gladly sacrifice 'it' if necessary, Stein is visibly angered by her. However, later chapters make an attempt to make Stein appear more humane and not simply the 'hedonistic sadist' Spirit pegs him as during the fight, so the 'evil' is debateable.
Arachne was dubbed a 'heretic' by her own kind when she killed a witch in order to create the first Weapon. As the witches are largely presented as Always Chaotic Evil, this probably counts.
Kiyotsugu Gowa from Gasaraki is a Mad Scientist, but he's appalled when he finds out that his own sister Misuzu is a kai (a person able to synchronize with the mecha of the series) and refuses to tell this to his brother Kazukiyo out of fear of what he'll do to her. He also refuses to use an untested and fatal Psycho Serum on test pilots, so another Mad Scientist does it instead.
In Holyland, most gangsters don't respect Combat by Champion and gang up on the victor if he's not the one on their side. Thus, it stands out when the gangsters gathered to watch Yuu fight Katou refused to gang up on the former and when the latter was beaten, some of them, including Tsuchiya, did not want to lynch the victor. This foreshadows Tsuchiya's Heel–Face Turn.
Later on, even Ryuu, the more insane of King's two henchmen, is creeped out by Katou.
In Naruto, more than one villain is repulsed by another's actions:
Zabuza Momochi expresses his disgust with Gato for double crossing him (and desecrating Haku's corpse), and is extremely pissed off because Kabuto brought him and several others back from the dead to use as mindless drones.
Zabuza: This is bullshit, I don't want to fight for someone who would stoop this low.
Even Makoto has one as he despises bullies in one of the game's endings where he stood up to the Girl Posse the same ones who backstabbed her friend by videotaping her having sex with Makoto, then having sex with him, and showing the tape to the whole school.
Dr. Eggman from Sonic X once tried to blow up a city of completely innocent people, but can't stand torturing victims, as shown when he witnesses Black Narcissus torturing Chris and Cosmo and says, "I'm not above evil myself but torturing people is just plain wrong."
He also in one episode alerts his arch-nemesis, Sonic, that the Metarex are planning to kill him and his friends stating that "if anyone is to get revenge on that hedgehog it's going to be me! And through less brutal means!"
When Sonic is apparently stuck on earth while his friends are in their world, Tails, an 8 year old, takes on Eggman's new space carrier in his plane. Eggman orders his Hench-robots to fire a homing missile which homes in on the plane. When the missile is near to hitting Eggman says to call it back (he only sent it towards the plane to scare Tails) however is told that there is no "call back" button. Eggman is horrified at the thought that he has killed a child. Tails, however, is saved in the end.
"I'm going to have to live with the thought of killing Tails forever!".
Eggman seems to have a soft spot for characters such as Chris or Tails perhaps because they're the smart, logically inclined inventors of the group and thus maybe they remind him of himself. When Tails has to kill Cosmo in the third season finale, Eggman is the one who talks him through it and reassures him that he knows how difficult it is, but it's this or the end of the universe. While he accepts that it's necessary, he doesn't celebrate killing a child, nor does he celebrate the fact that one of his arch-nemesis's friends is the one who has to do it.
As shown in the season one finale, where his robot is going insane and beating poor Sonic to death. Chris (who was Eggman's prisoner at the time) is crying for him to stop. Eggman tries to get his robot to stop.
In the light novel of A Certain Magical Index, Accelerator quotes this quite often when fighting other evil people, then goes to show them "what being a true villain is all about" usually ending with a swift death.
Ironic because Accelerator himself has moments of this trope, especially when Last Order is around.
Shizuri Mugino, one of the most psychotic characters in the franchise, is sickened and horrified by cannibalism.
Piccolo decides to aid Goku in fighting Raditz because he wants to Take Over the World as opposed to Raditz' plan to Kill 'em All. This and his time with Gohan are the impetus for his Heel–Face Turn. He's also pretty seriously indignant at the implication that he's going to eat Gohan when he takes him for training.
Piccolo is also disgusted when Vegeta kills one of his Saibamen for failing to kill Tien (which makes sense since even King Piccolo was a Father to His Men). Nappa is equally shocked.
Though Android 17 is a killer cyborg specifically created to kill Goku, he actually hates Dr. Gero and only follows his programming out of boredom, and doesn't endanger innocent people; thus, he's disgusted that Cell literally drank600,000 people.
In spite of being enslaved by Babidi's magic, Yamu retains enough of his humanity to be disgusted and angered by Spopovich's Cold-Blooded Torture of Videl in their battle. When the latter was about to kill the girl, he could tolerate it no longer and erupts:
Yamu:ENOUGH, Spopovich! (With a look of genuine pity and sadness for Videl.) This isn't what we came here to do; ring-out the girl and finish this match.
In Dragon Ball Super, Ro and Sidra, the Supreme Kai and God of Destruction of Universe 9, is shocked when Frieza offers to join Universe 9 instead of being in Universe 7. Despite being the more amoral of the weaker universes, both are shocked when, in attempting to appeal to something that Frieza may like in Universe 7, Frieza wholeheartedly admits that wouldn't mind if Universe 7 rolled over and died.
Ro:' He's a psychopath who doesn't care if his own universe gets erased!
Frieza of all people is shocked to witness the two Zen'o erase Universe 9 from existence. It's not so much the act itself (which he does recognize as horrendous), but their playful attitude and Ambiguous Innocence towards it.
Alucard may be an Ax-CrazyCombat Sadomasochist, but he knows that he's a monster and when someone goes too far. One of the reasons he serves Hellsing is because he hates the vampires of the modern era not only for being far weaker than he is but also for abusing what little power they do have. Specifically by turning people into ghouls, and Alucard is above that. And the Major starting a war on England just because he likes war... even Alucard thought he was a lunatic! (Specifically, a lunatic on par with himself.) Sure, he killed a bunch of human police officers when they stormed into the hotel he was staying in, but they were the ones attacking him! Plus, due to his Undying Loyalty to the Hellsing Organization, he has a strong distaste for traitors. Lookin' at you, Walter. And becoming a monster for the sake of defeating him? He... doesn't approve of that, either. Anderson finds this out the hard way.
Speaking of FatherAlexanderAnderson, the good priest tends to follow his own set of rules, regardless of what Maxwell tells him. He willingly protects Integra despite being given orders to kill her, which appears to stem from genuine respect and the possibility that she'll lead him to Alucard. He scolds his Iscariot followers and protégés for mistreating and threatening her, reminding all of them that they're "paladins, not rapists". Even the thought of manhandling Integra seems to disturb him. He's also a Gentle Giant who adores children and will not fight Alucard when civilians are in the immediate vicinity. However, the biggest comes when Maxwell goes absolutely nuts with power and kills the innocent survivors of the London attack for no reason other than their Protestant beliefs. Anderson believed that he betrayed God and the Vatican for his actions and decided to waste him. He even became a monster only because he believed there was truly no other way to defeat Alucard.
Enishi slaughtered a family — babies and young children included — who nursed him back to health, just because he was sickened at the fact that they were living happily while his older sister Tomoe was dead, but it's been implied that he doesn't kill young women. Not that Enishi might not want to kill them, but because he psychologically can't kill young women because of the nature of Tomoe's death, who was around 17/18 when Kenshin accidentally killed her in front of a 10-year-old Enishi. This was why Kaoru (who is around the age Tomoe was when she died) was spared in Enishi's plan for revenge against Kenshin, and instead of being downright murdered, Enishi went through the trouble of hiring a master puppet maker to craft an extremely elaborate doll in Kaoru's exact likeliness.
Can also be seen in Gein, who is extremely disliked by his own companions.
Invoked by Makoto Shishio, who roped Anji Yukyuzan into the Juppongatana with the promise of letting him decide about the life and death of his enemies since he knew Anji was still very lawful and honor-bound. Predictably, when Anji sees Usui attempt to stab an indefense Misao In the Back, he invokes this trope and stops Usui with his bare hands. Overall, Shishio is evil and well aware of it, but at least he's honest about his villainy and can't stand the dishonesty and hypocrisy of the government whenever it commits comparably heinous acts while claiming to represent democracy and peace.
Akira Hongo, the "God Fist" of the antagonist YAMI group, proves to be an interesting case of this trope. At one point, while he's confronting Kenichi and Miu about the death of his disciple Shou Kanou in the earlier D of D Tournament arc, Ryozanpakou masters Shigure and Apachai attack him. However, he effortlessly puts them off without actually fighting back, because Apachai is still injured from his earlier fight with his rival Agaard (a fellow YAMI member) and because Shigure is a woman.
Speaking of Kanou, a flashback near the end of the D of D arc reveals that, for all his cool-mannered exterior, Hongo really did care about his disciple. In the present day, Hongo was greatly displeased upon first learning that Kanou was dead.
Much later, Hongo did not take it well when other fellow YAMI member Silcardo Junazard tricked him into almost killing Kenichi while he (Akira) was fighting in an unconscious state in order to fulfill his bigger objective of kidnapping Miu. He wound up in an Enemy Mine alliance with Ryozanpakou because of it.
Apparently, the One Shadow Nine Fists group leading Yami has a good degree of standards, as nearly all of them care about their respective disciples in their own way and are at least willing to submit to the unspoken rule between them and Ryozanpaku that master-class fighters should not interfere in their disciples' fights nor interfere in a match between two other master-class warriors. The sole exception among the Nine Fists is Silcardo Junazard, who has broken both rules, showing himself to be very willing to kill his own disciples if they don't meet his standards, and crossed the Moral Event Horizonby his aforementioned manipulation of Hongo to nearly kill Kenichi so he himself could take advantage of Miu's chaotic mental state and kidnap her to brainwash her.
In fact, Junazard's misconduct is so severe that we get to see just how the One Shadow Nine Fists group has standards despite being the series' antagonists who advocate the killing-fist aspect of martial arts: Hongo seeks audience with the One Shadow prior to undergoing the above-mentioned Enemy Mine, presumably to get permission to fight and kill Junazard, and the One Shadow himself also gets involved in Miu's rescue, albeit going there incognito.
Isshinsai Ogata, another member of the One Shadow Nine Fists, won't hold back against opponents who step up to challenge him, and won't hesitate to kill you if you fight him with the determination of a martial artist. But as a flashback reveals, he was not happy to discover that he'd unknowingly killed an unborn child when a pregnant fighter stepped up to challenge him. He actually calls that discovery an unfortunate tragedy when it's revealed in the present day.
The disciples of the unarmed division of YOMI do not like the way the armed division fights. The unarmed branch all agree to one on one duels, while the armed branch is just fine wirh Zerg Rush tactics.
Panty & Stocking with Garterbelt features the Demon Sisters Scanty and Kneesocks who are pretty determined to take down the human race, but are much more polite and rule-abiding compared to the Jerkass angel protagonists. Perhaps the crowning moment is when Scanty expresses a great disgust when Panty and Stocking are perfectly willing to let Brief die at the Demon Sisters' hands, much less not bother to say his real name.
Likewise, on the angel's side, Panty has almost no moral standards whatsoever, and yet as foulmouthed as she is, she can't stand hearing the word "moist".
The Emperor from Code Geass is a man who allows his people to brutalize, slaughter and abuse anyone in captured areas, simply because they aren't Britannian. He's NOT a nice man and most of the world hates him for very good reasons. That said, he will not stand for lying. He watched his family murder each other in power grabs with lies and absolutely despises anyone who plays a role. As a result, when he found out that his brother had lied to him about killing his wife and Lelouch's mother Marianne, he stole his code and let him die for the action when he had the chance in R2. This does make him a bit of a hypocrite, as Lelouch points out. He put on his own mask as Emperor to hide his true goal of making a world without lies.
Cornelia is a Lady of War, and had her share of war crimes against enemy's population. But if your plan involves nuking your own population, she'll never side with you. Notice that Cornelia hasn't done anything evil since… at least the declaration at the school festival.
Kanon was shocked when Schneizel reveals he has no intention of rescuing his own half-sister Nunnally, since he was using her as a bait to kill Lelouch.
And Schneizel himself is shocked when Euphie is killing innocent Japanese left and right. Although in this case, she was inadvertently Geassed, not intentionally being evil.
Schneizel also abandons the High Eunuchs when they call nations dirt, leaders replaceable figuredheads, and the people ants. He rescinds their deal to become Britannian nobles and leaves them to their fate at Xing-ke's hands.
A comedic example in the sound dramas of Mai-HiME. Nagi may be a Manipulative Bastard who is working for the evil Obsidian Lord, but he reminds the viewers not to drink before they're 20, unlike Mai, Natsuki, Mikoto, Nao, Chie and Aoi.
In Rosario + Vampire, Kahlua actually begged Gyokuro to reconsider when the latter put a hit on Kokoa.
From Jormungand, Koko Hekmatyar may be a weapons dealer not above making a profit off of war and crime, but you do not harm her subordinates or children in her presence, despite of the fact that she has contributed to the deaths of myriads of people with some children inevitably among them (but hey, since they were not in her presence it's okay right?). And don't even think of paying her in drugs. (Or credit).
In Ah! My Goddess, Marller captures Urd and splits her demon and goddess halves and transfers the demon half into an artificial body. One of the first things Demon Urd does is seal Urd's younger sister Skuld in a magic mirror. Marller thinks this was a little harsh.
Koro-sensei from Assassination Classroom has promised that he will destroy the world in one year's time unless he can be defeated, yet when one of his students endangers the life of a classmate, he flies into a berserker rage and threatens to kill the boy's family if he ever tries something like that again.
After Nagisa defeats Takaoka the three assassins he hired reveal that they did not infect their friends with a synthesized virus like Takaoka planned. Instead giving them a very nasty but temporary case of food poisoning. Even professional assassins draw the line at killing kids.
In Attack on Titan, even the paranoid, vicious commander of the Military Police Brigade who was eagerly trying to have Eren executed a few moments ago is stunned at how far Levi goes in his No-Holds-Barred Beatdown.
In Fairy Tail, Despite everything Alpha Bitch Minerva has done at this point even she was frightened to see her Guild Members (from Succubus Eye, not Sabertooth) turned into mere paper by Kyouka of Tartaros, but considering her possible survival and boost in power this might be nothing. Still she also had decided not to just kill Erza when she was in her child form but Minerva replied she was just keeping her alive for her own pride.
Kyouka herself qualifies as well. She may not be above torturing prisoners of war, but she is nice to her own allies, (Except Crawford) and objected to when her boss, Mard Geer sacrificed so many Tartaros foot soldiers.
Tsurugi in Go, starts out as a SEED, working for Fifth Sector who was sent to Raimon to act as a SEED in their team. He begins to turn against Fifth Sector however, when their other SEEDS attempted to break Tenma's legs on purpose. His disgust at this is mainly due to his brother having broken legs, and therefore not being able to play soccer. What really sets him off, and makes him charge towards the goal to score for Raimon, was the line "Someone like him doesn't even deserve to play soccer".
Kidou in the original series although not a bad guy, is portrayed as being the captain of the "enemy team" at first. He is completely disgusted when he sees the team's coach, Kageyama's plan to crush the entire Raimon team to death fail. Kidou works said plan out ahead just in time, and warns Endou.
Again, not "evil" so much as arrogant Arbega, Captain of Gurdon's team, is enraged at Rodan's trap to crush Earth Eleven under magma rocks, saying that he went way too far.
Happens a lot, where a team that's portrayed as "evil" finds one of their fellow team-mates/coach's methods of winning a match unjust.
In Beast Saga, Bilsword is disgusted at the fact that his fellow officers would deliberately kill subordinates who have families to return to without hesitation.
Played for laughs in The Devil Is a Part-Timer!, when Alciel, the unrepentant right-hand servant of Satan, is horrified to discover that his temp job involves working for a company that scams people into buying worthless merchandise.
Lucifer is a Fallen Angel who, in his first appearance, went on a destructive rampage through the city for fun, but when his then-partner Olba Mayer tries to chew out Emi for teaming up with Maou, even Lucifer himself calls him out on the hypocrisy of his statement.
Kuniko's supporters in Rolling Girls begin to turn on her after her plot to lure Maccha Green into a confrontation begins to endanger the lives of the hostages they took. They were more than willing to kidnap a bunch of teens to set up the trap in the first place, but actually killing them was something nobody but Kuniko had ever actually considered.
This is the whole reason Ai ends up joining the other girls in their trip across Japan. She was originally one of the Mooks working for Kuniko, but got kicked out of the group after she tried to punch Nozomi in the face. Her former teammates even comment that it's illegal to physically assault non-combatants.
Esdeath is one of the clearer examples among the Jaegers. As much of a sadist as she may be, she finds Wild Hunt to be obnoxious and disgusting, most notably, and she found Seryu to be far too Ax-Crazy, so she told Kurome and Wave to loosen her up and reel in her Sanity Slippage.
Speaking of the Jaegers, of course, even the worst members of the group itself have a strict moral code.
Prime Minister Honest may be an Evil Chancellor, a Manipulative Bastard and the root of all corruption in the empire, but even he has standards of his own. For starters, he actually feels sorry for Tatsumi when he ends up being Esdeath's lover. When Esdeath decides to drink an entire vial of demon blood, Honest immediately tries to get her to back off since it could've killed her. He makes a toast with her once she proves him wrong by surviving and taming the demon blood.
In Magical Girl Apocalypse, Parasite-M is a homicidal maniac, but is disgusted when Akuta offers to betray his comrades in exchange for having his life spared. She calls him a piece of shit.
Jojos Bizarre Adventure: Diavolo, the main villain of Part Five, is the head of the Passione crime syndicate. He is not above drug-dealing. He is perfectly willing to murder his own daughter (who has never met him) in order to keep his identity secret. Even he despises Cioccolata, to the point of dismissing him as "human garbage". The only reason Diavolo keeps Cioccolata around is because it's better to have his powers working for him rather than against him.
Jotaro, while being a protagonist of Part Three, is openly introduced as rough delinquent who casually admits that he's a bad person, but even he has lines he won't cross in his first battle with Kakyoin:
"Look. No one ever said Jotaro Kujo was a nice guy. I beat the crap out of people, more than I have to; some of them are still in the hospital. I've had idiot teachers who liked to talk big, so I taught them a lesson... and they never came back to class. If I go to a restaurant and the food's bad, I make it a policy to stiff 'em with the bill. But... even a bastard like me can spot true evil when he sees it! True evil are those who use the weak for their own gain, then crush them with their foot when they're through! Especially an innocent woman! And that is exactly what you've done, isn't it?! And your Stand gets to hide from the victim, the law and the consequences! That's why... I will judge you myself!"
With the exception of Byakuya and those who were killed way too fast for them to actually form an opinion, not even Naraku's various detachments can stand him. That's right, even the parts of Naraku's own body hate him; he's that much of a dick.
Garamaru, the brother of the moth demon bandit Gatenmaru, finds his brother's preference to drink human blood uncouth, and thus laughs off Inuyasha's assumption that he came after him to avenge his brother's death.
In Hunter × Hunter, depraved Blood Knight Hisoka has an unhealthy interest in the potential of Gon and Killua to become worthy opponents he can fight and kill in the future. Even he thinks that Illumi's obsession with his younger brother Killua is creepy. On a more normal use of this trope, Hisoka enjoys praise and admiration from audiences—and when fighting Chrollo in a competition, Hisoka is visibly disgusted when Chrollo starts using audience members as tools and as cover.
In the 2015 anime of The Heroic Legend of Arslan, high ranking Lusitanian officers like Guiscard and Montferrat are disgusted by Bodin's extreme and senseless murders of innocent Parsians and burning of the libraries, which are all potential assets. Other soldiers also voice their objection about Bodin's torture of the captive Shapur.
In Dangan Ronpa 3, Monaca disliked Nagito's attempts for her to become Junko's successor so much that she gave up on becoming the next Junko Enoshima.
Satoru Suzuki/Momonga/Ainz Ooal Gown the titular character of Overlord was perfectly willing to let the village of Carne be slaughtered while he watched through a magic mirror. Understandable, as he didn't have enough information to intervene, until he saw a full grown, armed and heavily armored soldier chase down, torment, maim, and prepare to execute two helpless little girls and shows disgusts, when said soldier proves himself a Dirty Coward when he intervenes.
Momonga: "You can chase down women and children, but you lack the conviction to face an enemy?"
He was truly disturbed when he saw what Clementine did to Ninya. Let's remember that by this time Ainz had already lost all empathy towards humans and his emotions were mostly surpressed. When he got his hands on Clementine, he made sure that she would pay.
Ainz: "You took your time killing her, didn't you? So I will take my time as well."
One of Ainz's most consistent and defining redeeming qualities is that he truly cares for those who serve under him, such as Albedo and Shalltear. Messing with a citizen of Nazarick is a great way to piss him off.
