Great Mazinger: Tetsuya and Jun have the same kind of gratitude and regard. Or even worse. In the manga episodes penned by Gosaku Ota -one of the Go Nagai assistants-, The Dragon Great Marshall Of Hell warned he would blow Tokyo up unless the Home Base and the Humongous Mecha of the heroes were destroyed. People demanded the Government yielded... And they did. The Fortress of Science was destroyed, and Tetsuya and his allies were forced to flee and lie low for a while. During that time they had absolutely NO help to try and keep defending humankind. They did get many insults, though.
Seto Kaiba from Yu-Gi-Oh! refuses to change his opinion of Yugi, despite the latter having come to his and/or his brother's rescue on at least three separate occasions. He has a Grudging Thank You moment at the end of Duelist Kingdom, even though defeating Yugi became an obsession for him in the following seasons.
At least he stopped trying to kill him in the manga. His opinion of Yugi did eventually change, but that was in episode 223, and it took seeing Yugi destroy ALL THREE EGYPTIAN GODS in one move for that to happen.
Lolly and Menolly from Bleach. After Orihime heals them both (including bringing Menolly back from the dead) from the mauling they got at the hands of Grimmjow, they still consider her a useless monster not worthy of Aizen's attention. When he leaves to take out the hometown, they decide to take advantage of Ichigo being occupied with another fight and try to beat Orihime to death again. It doesn't end well for them. They (or at least Lolly) actually hate Orihime MORE after she heals them. Ungrateful Bastard indeed.
Lolly:What is she... What... She's... She's... Like a monster...!?
This may not have been an increase in hatred, but shock/fear at realizing the full extent of Orihime's powers (Not everyday you meet someone who can bring people back from the dead.) Considering that Hollows/Arrancars/Espada/etc. are born from spirits of the dead that have remained in our world and become increasingly more corrupted, then this counts as pretty much seeing what Hollows would consider an Eldritch Abomination at work.. Quite the Fridge Brilliance there.
Lolly seems to revert from this to The Only One Allowed to Defeat You when Orihime is threatened by Yammy. Thus leading to her apparent permanent death. Almost, at least in the anime.
Not true, as it seems Loly lived in both the anime and manga. This is actually subverted as far as Menoly goes, as after the first incident, she seemed willing to just leave Orihime alone for fear of getting in trouble, but Loly pressured her into it.
Yammy also fits this description; After a nurse reattaches his arm, Yammy's first reaction is to crush her under his fist to test it out.
Rufa from Dragon Half, while not, technically, an enemy, treads close to this trope.
Frieza tries to kill Goku one last time after just getting his life saved. By this point, Goku's had enough and doesn't offer him the same deal thrice. Hey, sometimes he learns, it's just Frieza who couldn't.
Another Z example would be a bit earlier in that Saga, when Gohan grabs a badly-wounded Vegeta to get him out of the way of Recoome's incredibly powerful Breath Weapon (which probably would have instantly killed him). Just why Vegeta yells at him depends on the translation, but he's pissed off about it.
Vegeta has a history of this. When he intentionally wounds himself to the point of near-death, thinking Dende will heal him and make him stronger, he's horrified to find Dende refuses to do so (due to the rather-reasonable argument that Vegeta has killed a lot of Namekians). When Dende comes back and finally obeys, Vegeta punches him in the stomach, with a cry of "You little turd!"
Android #18 can also be considered as an example of this. Considering how high the stakes were when Cell was in his imperfect form, Bulma invented a detonation device to blow up the androids (who were still around during Cell's rampage), so Cell wouldn't absorb them and achieve his perfect form. Krillin was put up to the task of getting close enough to one of them so it would work. However, because of a kiss that #18 gave him earlier on, Krillin let his conscious get the better of him and couldn't bring himself to blow her up. This, combined with Vegeta's arrogance and Cell absorbing #18, lead to the transformation of Perfect Cell, along with the deaths of Android #16 and Goku (for the second time and a period of seven years). After Cell spat out #18 and was destroyed, #18 gave him less than a well-intended gratitude and does not return his feelings, even after asking Shenron to remove the bombs from the remaining androids. Even though to eventually marries him and they both a daughter together, she still treats him harshly, up until his third (technically fourth) death (many years later) in Dragon Ball GT.
An example that's neither villains nor rivals: The Obstructive Bureaucrats ordering around the Black Order in D.Gray-man. These jerks are supposedly on Allen's (the hero) side. Yet their reaction to him saving everyone's asses, hampering the Big Bad's ability to make mooks, and capturing the Ark at the end of the Ark Arc is to put him under surveillance and try him for heresy, despite the fact that it is known, in canon, that if he'd betrayed him he wouldn't still be walking around, let alone now one of their most powerful exorcists. Not only that, but they absolutely need him to continue their war, pushing this into Too Dumb to Live territory. Even worse now, they put him in a jail cell for not obeying orders when he was trying to save everyone.
In Busou Renkin , Kazuki risks his life to protect the Hayasaka Twins (the series' Ineffectual Sympathetic Villain) from Tokiko, who wants to kill them simply because they work for L.X.E. Shusui "thanks" Kazuki by trying to kill him. Kazuki gets better (thanks to Ouka), but even so...
Nabiki Tendô, of Ranma ˝. Ranma Saotome is not only engaged to marry her little sister in an Arranged Marriage, but protects the household on a fairly regular basis from various chaos. Admittedly, some of that chaos comes to them because he's living there, but there are many events that would have fallen on the Tendôs' doorstep anyway (PicoletChardin showing up to claim one of them as his promised wife, Akane running off to Ryűgenzawa and its resident Orochi, Happôsai coming to town...). He's also directly saved her from harm at least once, and once saved her life. How does she repay him? She's utterly indifferent to his well-being and considers him solely a source of money and amusement, to the extent she's willing to put his life in danger if she thinks it will make her some money.
There's also a subversion: As Genma Saotome frequently complains, Ranma Saotome is an "ungrateful son"...except in Ranma's case he's kind of justified, because everything positive Genma did for Ranma was what a father is supposed to do, while Genma also added a lot of unnecessary negative complications that he then left for Ranma to fix. Really, Genma himself is an example of this trope, ungrateful that Ranma does constantly clean up after his messes.
In NarutoSasuke Uchiha became this recently. While attacking the Kage conference, Suigetsu and Jugo save his life, as they had against Killer Bee earlier. However, Sasuke leaves them both to die without looking back, collapsing the ceiling on them and the enemies alike. Later on, Karin heals him back from the brink of death (again, saving his life twice counting Killer Bee and the Kages) and helps Sasuke defeat Danzo. When Danzo takes her hostage, Sasuke aims his Chidori Spear right through her, considering anyone dumb enough to be taken hostage a burden. She survives the spear, and just as Sasuke is about to kill her with Chidori, Sakura shows up and claims to want to join them. Sasuke (who even now isn't that stupid) tells Sakura to kill Karin, who manages to warn Sakura that Sasuke's about to chidori both of them. It should be noted that as much of a rabid Sasuke fangirl as Karin is, she doesn't take being skewered well.
Also, the treatment of Naruto by the villagers. If the Kyuubi hadn't been sealed inside him, it would have destroyed Konoha, but he is a pariah because of it. Over time, this gets better as they see how much Naruto has accomplished and start regarding him as a hero.
In Pokémon, Ash's Charizard used to a major example of this. When it was still a Charmander, its former trainer abandoned it on a rock, leaving it on the brink of death on a rainy night. Ash had saved this Pokémon and took it with him on his journeys. It would eventually evolve into Charmeleon and start disobeying him. Upon evolving into a Charizard, its attitude doesn't improve much and actually costs Ash the entire Pokémon League Indigo Conference. It isn't until late in the Orange Islands arc that Charizard finally comes around.
Also Lampshaded when Ash saves the Team Rocket trio. While Jessie claims it doesn't change anything and begins ranting at the heroes for saving them James interrupts saying that he, at least, is thankful. This doesn't stop him doing villain stuff a few seconds later.
In one episode of Samurai Champloo, the trio supposedly meet Xavier III whose trying to spread Christianity to Japan. However he turns out to be nothing but a con man taking advantage of the locals. A girl name Yuri, whom he mercilessly abused, has him at gunpoint and is all set to kill him. But she eventually just tells him to get lost and spares his life. He responds by trying to kill her. Karma however stepped in when after a brief fight a giant cross gets dropped on him.
The Council are this towards Fairy Tail. On occasion this makes sense, since usually Fairy Tail just rounds up random minor criminals while destroying half the city in the process, but they also get punished when stopping potential calamities without causing trouble in the process
In one of Genzo's story arcs, a limp old man named Yasuke asks Genzo to made an artificial leg for him. As soon as Yasuke get his new limb, he tries to chop the puppetmaster with his Yamiganemaru blade.
In a sense, Villetta Nu of Code Geass could be considered this for convincing Ohgi, whose love she finally accepted, to lead the charge of the Black Knights in turning on Lelouch because of some rather questionable evidence of Geass. Yeah, even though she had been keeping surveillance over Lelouch because of said power, which she must have known had limits, and that Lelouch saved Ohgi from execution via Britannian firing squad, which he had to do by going under Villetta's radar. Now alright, Lelouch didn't necessarily do it for Villetta's sake, but talk about a complete lack of class.
One Piece has Zeff providing Don Krieg with food to feed his starving crew with, only for Krieg to immediately turn around and attack the restaurant who had just saved both his and his crew's lives.
Of course, Krieg did give everyone in the restaurant time to evacuate before he took it over; still Jerk Ass behavior, but quite a concession coming from him, albeit partly necessitated by his men needing time to eat and regain their strength. A better example would be when Don Krieg himself was starving. Everyone else present loudly and proudly declared their intent to just let him keel over and die, with only Sanji willing to step forward with food for him. Once Don Krieg is done eating, the first thing he does is get up and punch out, of all people, Sanji. For absolutely no reason.
The Longarm tribe, who Brooke decides to work with and proceeds to earn them a lot of money and fame, repay him by turning him over to the Navy when Brooke tells them that he plans to retire and return to piracy.
In One Piece Film: Strong World, the Straw Hats go out of their way to warn Golden Lion Shiki about an incoming typhoon. After they avoid it, he repays them by kidnapping Nami as his new navigator and sends the rest of the crew pummelling down towards his floating islands as prey for the animals there.
Myosgard, after just having his life saved by Queen Otohime, tries to shoot her. Then again after he is healed up, all he shouts is his disgust towards having to be with them. And lastly, he voices his anger when Otohime wishes to come with him on his ship.
Viper Snakely from Kimba the White Lion. Even though Kimba gone against his desire for revenge for killing both of his parents and saved his life from a car crash, Viper Snakely continues to hunt for Kimba and sometimes kill some of his subjects.
In The Plot to Assassinate Gihren Zabi sidestory in Mobile Suit Gundam, Det. Leopold Fiesler discovers that a year before the current plot against Gihren was launched, a previous attempt had been thwarted by Det. David Schiller, whose family had ties to the anti-Zabi political faction. Gihren used the failed assassination as an excuse to crack down on his political rivals, ultimately imprisoning or executing Schiller's entire family (none of whom were involved in the plot). Ungrateful indeed.
In Kenichi: The Mightiest Disciple, Niijima is this way towards Kenichi early on. He berates Kenichi constantly, and when Kenichi starts getting stronger, he uses him largely for his own selfish gains. Niijima does more or less grow out of this trope, and turns into more of a Guile Hero, especially after he forms the Shinpaku Alliance.
In Girls Und Panzer, this lies at the heart of Emi's grievance against Miho's sister Maho in Little Army. It turns out that during the tournament Maho won, when one of the tanks on Maho's team fell off a cliff, the opposing team's (of which Emi's older sister was a member) flag tank went to help, but Maho ordered her tank to fire on the flag tank, even though she was winning. However, Maho's expression when it's first brought up not only indicates shame over doing so, but also quite possibly ignorance of what the flag tank was trying to accomplish.
The X-Men. They can save the world over and over again, and the public of the Marvel universe will still hate and fear them. This is particularly notable during any origin arc, most all of which can be summarized as "Hey, those mutants saved us from that rampaging robot/alien/supervillain/whatever, let's throw rocks at them!"
In Messiah Complex, Mystique saves her daughter Rogue's life, and Rogue responds by trying to kill her because she had risked an infant's life to do it. To be fair, it's Mystique, who's tried to kill her daughter's friends/family the X-Men multiple and murdered dozens of innocents.
Also, mutants were an endangered species at the moment (less than two hundred around the world), and the baby in question was The Messiah with the potential to restore the mutant population. Rogue didn't want to live at the cost of the mutant race dying out.
Spider-Man can save J. Jonah Jameson, JJJ's family, and indeed the whole city of New York all day long if he likes; next morning, the Daily Bugle headlines are still going to be reading "Threat or Menace?"
There's the occasional hint that Jameson actually does like Spider-Man, but that he puts on the horse and pony show to sell newspapers. And far more regular hints that JJ can't stand him. Actually, JJJ clearly stated that he was jealous of Spider-Man, all the way back in the tenth issue.
There's also enough evidence that New Yorkers, even if such mass consumers of Accentuate the Negative to make the Daily Bugle the number one paper, aren't as pliable to the mass media message, and will rally behind Spider-Man. This also pisses off J.J., but the only thing he likes more than subscription numbers is to be pissed off, so everyone's happy.
Some of the New York City Cops are also more on the ball than their colleagues, and will cut the wall-crawler some slack when he makes their lives easier. On rare occasions, more belligerent cops will be called out by their partners, who point out that Spider-Man didn't actually do anything wrong.
Spider-Man once did have a close ally in the NYPD: Captain Jean DeWolff. Sadly, she was murdered by Stanley Carter, the original Sin-Eater, her ex-lover. (Jean may have even had feelings for Spider-Man that were warmer than he had originally thought, as evidenced from a collection of photographs he found of the two of them together that she kept; one of them, that had included the Black Cat, was altered so that the Cat was removed.)
Subverted in one older issue when on patrol, Spidey notices an old woman being mugged; he stops the mugger and returns her purse. She thanks him sincerely, promises to never read or believe JJJ's editorials from then on, and wishes him good luck in the future as he swings away.
Hell, the whole Marvel Universe as a whole are filled with ungrateful bastards, quick to turn on the heroes for no good reason or if they make a mistake despite getting their asses saved from Galactus, Magneto, Doctor Doom, etc., Civil War demonstrating that behavior. Then again, Marvel citizens are pretty much dumbasses so it's not really surprising. That said, the occasional moments when ordinary people actually show gratitude to the heroes are all the more satisfying, and can serve as Pet the Dog moments to make them likable to the readers.
The assholishness of the Marvel Universe inhabitants is so pronounced that, when the Avengers hopped to the DC Universe in JLA/Avengers, they were flabbergasted when cheering civilians mobbed them with grateful thanks (and autograph requests) for saving them from a disaster, and upon seeing how much positive media attention the JLA got for their heroics, Captain America became suspicious that the DC Superheroes were tyrants demanding worship from humans.
To further home what a Crapsack World full of Jerkasses and dragon bulliers and other morons the Marvel Universe is, upon seeing how the Marvel Universe treats its superheroes, Superman accuses them of not doing enough to help people, claiming this is the only reason why they could be so hated by the people they are supposed to protect.
Superman can save the whole frakking universe over and over again, and the government will still create Cape Busters to attack him. Supe's son, Chris Kent (Nightwing), and his girlfriend, Thara Ak-Var (Flamebird), almost always get attacked the second after they finish a rescue.
Was even worse in the beginning of Superman. From time to time he would lose his powers for a few days or so and would get a replacement. In this time of course, everyone simply forgets all his deeds he has done, there would be parades for the replacement for things Superman did every day and sometimes people would even insult him for becoming useless.
And on occasions when it would even only slightly seem as if Superman would do something evil, everyone would consider it the truth (maybe except Lois and Jimmy, and sometimes not even them) and think he was evil or abandoned the city.
However, perhaps as a way to distinguish it from Marvel, this quality was reduced considerably (though inconsistently) in DC humans over time to the point where hurting Superman is pretty much a Berserk Button for the entire city of Metropolis.
Supergirl, again, dealt with this with Cat Grant after saving her life (and accidentally breaking Cat's arm in the process). This led Cat to go on a surprisingly effective smear campaign against the Girl of Steel. In the end, Supergirl merely left a note on her desk promising never to rescue her again.
As befitting a Sociopathic Hero and Villain Protagonist, The Punisher is this trope to the extreme. Not just to criminals who even risk their lives to save his own (it won't even buy you a decent death), but also to his friends. Even for the innocent, getting even a thank you out of Frank requires you to go above and beyond the call of duty.
Think the Fantastic Four is immune to this? Think again. After numerous supervillain attacks on the Baxter Building, Child Protective Services accused Reed and Sue of being bad parents towards Franklin and Valeria. After much protest, they agreed to relinquish custody of their children; however, less than four hours after the officials publically announced they were moving the two children to a safehouse, the safehouse was attacked by an unknown enemy and it - along with everything in a half-mile radius - was reduced to a smoldering crater. Fortunately, Reed had thought ahead of time - it had been a "dummy" safehouse, a condition he insisted on before he agreed to the terms, and miraculously, there were no casualties. Humiliated, the officials rescinded their decision. Unfortunately for the Fantastic Four, no-one ever found out just who had attacked the decoy safehouse, and many accused them of doing it themselves in a ploy to get their children back. Well, maybe it's possible that they did, but even if that's true, the point still stands: If you think you know better than Reed does, he's going to prove you wrong.
In The One-Handed Girl, the girl refused payment for a pumpkin, instead giving it to her sister-in-law. When the sister-in-law tries to get another the next day, the girl is out, so she tells the girl's brother that the girl had refused to sell her any, even though she sold them to other.
The Brothers Grimm story The Bremen Town Musicians features a donkey, a cat, a dog and a rooster who are all past their prime years and no longer able to perform their services for their masters. Instead of allowing the animals to spend their final years in peace, each animal's owner plans to simply dispose of their beasts and replace them with newer animals. The animals decide to set off on their own.
In Team 8, Naruto's team of himself, Shino, Hinata and Kurenai fights a team of missing-nin that kidnapped Konohamaru and Hinata's younger sister Hanabi. After being released, Hanabi shows little gratitude toward her rescuers, particularly her older sister Hinata, and expresses disdain toward her for getting knocked out first.
In one The Legend Of Zelda fic, Link finishes up saving a village only for the mayor to throw him out because of the amount of damage Link caused. Link himself knew he was going to cause damage and was willing to fix it up, but the mayor's reaction sends him into a minor Heroic BSOD (He gets better).
The Immortal Game: After the Mane Six strip Terra of her power, they vote to spare her life and imprison her. She mocks them for it and calls them weak.
Sakura in Naruto:Asunder. Long story short, Naruto brought Sasuke back to the village but had to place a seal on him (Jiraiya taught him the basics and Naruto found a unique way to make his) that put Sasuke in a coma. The seal makes it so Sasuke has to face what he was becoming (Naruto admits he was pressed for time so couldn't get specific with the seal) or he stays in a coma. Sakura keeps bitching even when it's pointed out she didn't do anything to help.
Drago betrayed the Matriarch (Jade's future self) and tried to write her out of the timeline, even though she — against the advice of her advisors — gave him a chance to redeem himself, rather than simply seal him away again. Both Karasu and the Matriarch herself point this out when fighting and punishing him (respectfully).
The Incredibles has superheroes go into hiding to escape being sued by the people they saved. To be fair, the ones we see ends up hurting most of them pretty badly.
In the finale of The Hunchback of Notre Dame, Judge Claude Frollo throws Quasimodo off the wall of Notre Dame but is dragged along with him. Esmeralda catches and holds Quasi's hand who holds Frollo. Despite having learned that Frollo had murdered his mother, Quasi is unwilling to let the bastard go. Frollo manages to get to relative safety and... immediately tries to kill the heroes. Relative was the keyword.
Cera in the first The Land Before Time movie. Littlefoot's mother saves her and Littlefoot from being eaten by Sharptooth. Even after this sheremains racist against "longnecks", even going so far as to call Littlefoot's mother stupid.
She gets better eventually.
Lotso in Toy Story 3. Basically, Woody and Buzz risk their lives to save him near the end, then when he has a chance to save them with no risk he deliberately leaves them to die in the incinerator.
Woody has his moment in Toy Story 2. Buzz and friends go to great lengths to get up to the apartment and rescue him from toy collector Al, who is preparing to send him to Japan. The most prominent expression of this is when Buzz gives a heartfelt speech about how he once taught him that life was only worth living if he was loved by a child and he came to rescue him because he believed him. His response? "Well, you wasted your time."
Woody does see Buzz's point and tries to leave with him almost immediately afterward.
Stoick the Vast in How to Train Your Dragon could count as this when he finally finds out about Hiccup and Toothless. After inadvertently endangering Hiccup and seeing Toothless rescue him, he attacks the dragon and orders him captured after Toothless spares his life when Hiccup begs him to. Then he tells Hiccup that he's not his son just because he befriended a dragon, then he doesn't listen to his son's stories about how big the queen dragon is and brings what is apparently most of the village on an inadvertent suicide mission.Great parenting skills, Stoick.
The Swan Princess 2. Derek saves Knuckles from falling off a cliff, only to be pushed down the same cliff by him a few seconds afterwards.
Originally, at the end of The Lion King, Simba actually chases Scar to the top of a cliff, causing the evil lion to plead for his life, and that the hyenas were behind the death of Mufasa, Simba actually tells Scar to "run away and never return", but Scar responds by throwing burning embers into Simba's face and attacking him while he is blinded. He doesn't survive after his fight with Simba, though thanks to his blame on them, it takes the hyenas to finally finish him.
The sequel has Kiara attempting to save Zira from drowning in a river, but Zira refuses her offer and decides to drown anyway.
In the sequel to Disney"s Pocahontas, After saving a man's life, Pocahontas gets knocked down by that same guy and to add insult to injury he calls her a savage.
Films — Live-Action
In Hellboy II the civilians swing from Muggles to Ungrateful Bastards ridiculously soon after the Masquerade is broken. Although the fact that Hellboy would seem to them to have gone from "cool urban legend" to "scary demon with huge guns who attracts enormous, destructive plant monsters"... And this is why the comics has him being public knowledge since day one (that's since the 1950's).
Lieutenant Dan in Forrest Gump is not only ungrateful, but downright angry with Gump for saving his life. This was mostly a pride thing, though, as he was the first in his family not to die in battle and didn't know what to do with his life afterwards, especially after losing his legs. If anything, by the end of the movie he becomes grateful to Gump for not just saving him, but giving him a reason to live.
"I never thanked you for saving my life."
In The Phantom, The Dragon Quill was once saved by the 20th Phantom, after he was attacked by a rabid monkey. Quill said that he would lead him to the Sengh Brotherhood's hideout. Instead, he stabbed the Phantom in the back, stole his belt and took it to the Brotherhood, who initiated him.
In Saving Private Ryan, "Steamboat Willie" is spared by the platoon... only to rejoin the Nazis, help kill the main character, Miller. No wonder shortly after he surrenders he gets shot. By the same guy who convinced Capt. Miller to let him go, in fact, right after he tries to get him to do the same thing again. To be fair Steamboat Willie is seen shooting Miller, but he's on the other side of the bridge, and he really had no way of seeing who it was he was firing at. The fact that it was Miller was simply a tragic coincidence. He later, in a rather Karmic fashion, killed in turn by Upham.
In The Lost World: Jurassic Park, Ingen's dinosaur capturing party rescues Ian and his team after a T-Rex destroys all of their equipment and leaves them dangling off of a cliff. They then provide all of the information Ian and co. need to get help and personally escort them there, despite heavy losses to their own ranks (most of which directly caused by Ian's group, of course). Despite all of this, Ian's team still feels the need to spend every minute of screen time possible heckling and sabotaging them. They even steal the bullets from them as they leave the island, leaving Ingen's team helpless against the attacking dinosaurs. That's manslaughter, or at the very least depraved indifference.
By the way, it should be noted that Ian's group are the supposed good guys in the film, keyword being supposed.
To be fair, Nick Van Owen was the only one who kept at it. Ian, Sarah, and Kelly just wanted off the island and had no knowledge of his continued sabotage until after they'd been rescued.
In Spider-Man 2, Spider-Man saves Harry Osborn from being killed when Dr. Ock's experiment blows up. Harry, who still thinks Spidey killed his father, tells him it doesn't change anything. As he leaves the building with his bodyguard, Harry says Spider-Man shamed him by touching him.
Happens in Escape From New York and Escape From LA, both of which end with Snake screwing over an ungrateful president. In the first one, the president shows no respect for any of the people who died in the process of getting him out of New York (though to be fair he had a lot on his mind at the time, what with him trying to stop a nuclear war and all). The president in Escape From L.A. makes the president in Escape From New York seem like an nice guy.
In X-Men: First Class, the mutants manage to stop World War 3 from occurring, putting their lives at risk in the process. How does the military thank them? By deciding that they're too dangerous to keep alive, and trying to kill them!
Star Wars: Anakin Skywalker himself from the prequel trilogy enjoys living this trope. He definitely qualifies during Attack of the Clones and Revenge of the Sith, where he puts the blame on Obi-Wan Kenobi for holding him back after Shmi, his mother, died in the Tusken Raider camp, assume that the Jedi Council weren't going easy on him and distrust them even more after he's refused the rank of Jedi Master, kills all of the Jedi, including the younglings, in the Jedi temple during Order 66 after all his devoted years of serving them, and, worst of all, Force chokes Padmé Amidala, his wife, to near death, after all his years of marriage with her, because he thought that she betrays him when Obi-Wan appears on her ship, so that the medical facility staff in Polis Massa will be unable to save her, leaving her eventual death inevitable. There isn't even any victory in his final defeat at the hands of Obi-Wan, because the victory for Anakin's former Jedi Master came off as Pyrrhic, resulting in the fallen Jedi apprentice being encased in black armor and becoming Darth Vader at the very end of the third prequel.
The Jedi in the EU are consistently feared by the Galaxy. And while this fear is warranted (the Jedi have had multiple civil wars, singular Jedi who go dark can wreck an entire galaxy, they have special powers), for a few examples, during the Vong War, a large portion of the New Republic felt that the best thing to do would be to appease the Vong by giving them the Jedi. As of this post, the New Republic (Galactic Alliance) is more fearful of the Jedi than the remnants of the Empire. Despite saving the Galaxy again and again, the Jedi just can't seem to catch a break.
In fairness to the Galaxy, Sidious ran a massive anti-Jedi propaganda campaign over twenty-three years, and Luke Skywalker mishandled Caridagate. Yes, Kyp Durron conquered his inner demons in the end, but announcing his investiture gave the pro-Order-66 crowd a huge propaganda victory.
In Anne McCaffrey's Talent series, early on the Talents provide a warning that saves the life of, among others, a Senator who's arguing vehemently to deny them legal protection—even though it also risks the life of their strongest defender. Undaunted, the Senator not only accuses them of perpetrating a hoax but also insists that real psychics would have known better.
Steve from the The Saga Of Darren Shan. Darren saves him by sacrificing most of his humanity after an accident. And how does Steve repay him, by becoming a vampire slayer and vowing to kill him. All because he thought Darren stole his original dream of becoming a vampire.
Jennifer The Jerk Is Missing. The title character is rude and insulting to her rescuers when she's found. "I like you better tied up and muffled," one of her rescuers says.
Jennifer: Oh, yuck! Malcolm Wylie, what are you doing here? I was hoping to be rescued by some handsome cop or maybe a federal agent or something.
Palicrovol in Hart's Hope, so much so that the book consists of a plea by another character for him not to kill Orem. It doesn't help that he contributed to the problem by raping the Big Bad, Beauty, when she was a child. So once Orem frees him and his closest friends — including the narrator — from their various curses, at the cost of Orem's beloved son, Palicrovol sets out to kill him due to Orem's time as Beauty's second-string consort. Discovering that Orem is his son (by a different woman) only prompts him to add incest to his list of charges.
In Robert E. Howard's The Pool of the Black Ones, Conan the Barbarian is rescued from the sea by a pirate ship. As soon as they make land, he goes to murder the captain so he can take over.
In John C. Wright's The Golden Age, the amnesiac Phaethon hears himself denounced as ungrateful and later learns that he is suing to have his father declared dead after his father had died to save him and been revived from a noumenal recording. Still later, he recovers his memory. He learns that his dying father had asked him to do something and pledged him monetary support so he could do it; he was suing to get the money to carry out his father's Last Request.
In Warrior Cats, Brokenstar plots with Tigerstar to take over Thunderclan, even though the same clan gave him shelter when he was blinded and saved him from being murdered by two other clans. Even his own clanmates don't treat him with the same kindness as Thunderclan.
No matter how many times Harry Potter saves his school, the students of Hogwarts will still turn against him on a moment's notice on the strength of lies purported by the government. Meanwhile, Harry never shows any gratitude to Snape for saving his life in the first book, or for attempting to save him and his friends from Sirius Black (at the time believed to be a mass murderer), or for saving their life again in Order of the Phoenix. Of course, Snape's a dick to Harry, but you'd think saving his life would merit at least a "thank you" from a kid whose defining characteristic is love. Harry finally gives Snape his due after he learns the truth by petitioning that Snape be awarded an Order of Merlin (posthumously) and naming one of his sons after him (Albus Severus Potter).
Draco Malfoy. Ron even lampshades it:
"And that's the second time we've saved your life tonight, you two-faced bastard!"
Anyone who has read Stephen King's Everything's Eventual will know that Diane, the character from the short story Lunch at the Gotham Cafe, is definitely this trope. You would think, that even after her husband just saved her life from a psychotic waiter, even after she treated him very coldly, not to mention demanding a divorce, would at least warrant a "thank you" from her!
Discworld heroes often get this, especially the ones who saved the world from certain destruction, because people become a lot less certain about how certain it was. In particular, we're told in Eric that there was some talk of building a statue of Rincewind after he saved the world from the Dungeon Dimensions (again) in Sourcery, but as the wizards became more determined to pretend it never happened (since they were the ones who started a magical war and opened the rift in the first place) this became a commemorative plaque, then a commendation on the roll of honour, and finally an official reprimand for being improperly dressed.
Sisterhood series by Fern Michaels: The protagonists, of all people, are these! Payback has Mark Lane save Julia's life, and instead of being grateful, Charles Martin sends three men with presidential gold shields to intimidate Mark, and the three men perform a No-Holds-Barred Beatdown on Mark's friend Jack Emery. In that book Deja Vu, almost all the men working with the Vigilantes up and leave, and Charles has to explain to the ladies that their men risk their lives, careers and reputations on a daily basis for them, and they have never shown any sort of gratitude for their men! Unfortunately, the ladies do not take that to heart, because the men successfully find the ladies' target, point out his location, and the women respond to this by performing a No Holds Barred Beatdown on their target in front of their men, without even allowing the men to have a piece of him! Ungrateful Bitches!
In Animorphs, new recruit and Sixth Ranger David is none too grateful to the team for saving his life, even threatening to walk off and try figuring out what to do on his own when they try to tell him what bird to acquire. Seeing as how the David trilogy never shows his side of the story, it's unclear if he's really just plain ungrateful or if he's holding a grudge against the Animorphs for leaving his parents behind to get infested (and in Ax's case, for chopping off his dad's finger).
In The Amazing Days Of Abby Hayes book The Best Is Yet To Come, when an old friend of Abby's mother named Laurie comes over to visit for the summer along with her daughter, Wynter, Laurie gets Abby to babysit Wynter for several hours a day. This doesn't seem so bad until we find out that Wynter is a huge spoiled brat and will only listen to Abby when she buys her candy, cookies, and various other sweets, forcing Abby to use up more and more of her own money to buy sweets to pacify Wynter. This goes on for several days until Laurie declares that she won't pay Abby at all (keep in mind, Laurie is a wealthy musician and could easily pay Abby what she owed her with more than enough money to spare) because she found chocolate in Wynter's sleeping bag that Abby gave to her. Granted, Abby's mother did eventually make Laurie pay up after arguing with her, but still...wow.
In A Song of Ice and Fire, Jaime Lannister is reviled by the realm for his betrayal of the Mad King, even by those waging war against him. Jaime considers the slaying of Aerys to be his finest act though, considering that Aerys was planning to engulf King's Landing in Wildfire to "burn them all".
In Speak, Melinda befriends the new girl, Heather, goes with her to a model shoot to support her, and assists her in her first Martha Project in order to help her get into the popular Martha clique, only for Heather to later ditch her completely in favor of the Marthas ("Look, you can't eat lunch with me anymore. I'm sorry. Oh, and don't eat those potato chips. They'll make you break out.") She pays dearly for it later.
The short story Boule De Suif follows a group of French residents fleeing to Le Havre. The title character, Boule De Suif, is a prostitute, and looked down upon by the other occupants of the coach, but she doesn't let that stop her from kindly sharing her food with them. Later, they are detained by a Prussian officer, and the rest of the party convince Boule De Suif to sleep with him, so that they may leave. She does so...and they repay her self-sacrifice by a) throwing a party without inviting her, and b) treating her with contempt when they are allowed to leave, and refusing to share their food with her, even though she's the reason they were even allowed to leave in the first place!
One of the most infamous events among the Wheel of Time fandom comes when Mat, a character who has yet to receive the massive power upgrades most of the cast manage to acquire, rescues Elayne and Nynaeve, two characters who are already insanely powerful, from a prison they had absolutely no chance of escaping. They proceed to berate him for daring to think they needed rescuing (they did) and offer no apology or gratitude until damn near forced to by Aviendha and Birgitte.
Little House on the Prairie: The 1979 episode "Barn Burner," which deals with the hardcore racism of a Walnut Grove-area farmer, has such an example at the episode's climax. Judd Larabee is being tried for barn burning in the aftermath of the destruction of Jonathan Garvey's barn; the offense carries an automatic death penalty upon conviction. Eleven of the 12 jurors have voted to convict Larabee, but one – Joe Kagan, the black farmer whom Larabee strongly hates – is not convinced Larabee was responsible; Kagan's instincts prove correct when Jonathan's son, Andy, admits he left a lantern hanging too close to the barn and it ignited the dry tinderwood. Larabee is acquitted ... and shows his graciousness by continuing to call Kagan every racist name in the book! Larabee pays a heavy price in the end, as his family leaves him and the other townsfolk shun him; it is implied that Larabee dies shortly thereafter of a heart attack.
The Jeffersons: Unlike what the episode title may imply, "Sorry, Wrong Meeting" is not a funny little story about accidentally walking into the wrong meeting, although the plot is most certainly about walking into the wrong meeting. To determine how to handle a series of burglaries in the Manhattan high-rise where the Willises and Jeffersons live, Tom plans a meeting; in the elevator, he runs into a man (who has just moved into the building) and his son, who are planning their own meeting. Tom — unknowing that the gentleman is the master of the local chapter of The Klan, and unknowing that the meeting is about running the Jeffersons out — offers to come. George, Tom and Mr. Bentley (also a white man) arrive and discover that they have the wrong meeting. A loud argument eventually ensues, with George's natural talent of wit (along with Tom's reasoning and Mr. Bentley also using sarcastic wit) thwarting the leader's racist reasoning at every turn. Eventually, the Klan leader suddenly passes out, and George — the only one who knows CPR — manages to revive him and save his life. However, when the man's son tells him that George had saved him, the leader promptly tells his son that "You should've let me die" as the paramedics take him away (The audience gasps in disbelief at this point). His attitude makes the other members realize what they're doing is wrong and, when his assistant tries to resume the meeting, the others all leave the club en masse, with the son — who had once admired his father and was starting to become the very racist image of him — apologizes and takes a look at his own values.
Played straight and averted in Stargate SG-1. Despite various team-ups with the likes of Apophis and Ba'al, both continuously try to destroy the SG-1 afterwards. Averted with Lord Yu, who was at least honorable enough to respect their deals, though admittedly he held to a higher moral standard than most Goa'uld, for instance being the only System Lord to vote against readmitting Anubis into their ranks, and not hiding behind a pretense of being a god. It's notable he was the only one still alive from the time Anubis was expelled, making him one of the more successful ones too.
Well, Ba'al has helped the SG-1 team on a couple of occasions against a common enemy, and once he even tried to settle down on Earth and made them the offer that he'd become a good lawful citizen and stay inconspicuous if they left him alone, but they still kept trying to kill him; or to capture him to take him to the Tok'ra to extract the Goa'uld symbiote... and then kill it. No rest for the wicked.
SG1 themselves were the Ungrateful Bastards when they left Fifth trapped in a time dilation field after he betrayed the other replicators to help them escape. This comes back to bite them in the ass... hard.
Much as the show liked to forget it, every Goa'uld was holding a host captive. Even if they weren't menacing anyone else, merely letting them "live their lives in peace" was an unacceptable situation — as proven by the trial over the Goa'uld and Skaara.
Also, Baal is not a nice guy who wants to settle down as a good lawful citizen. He's more Genre Savvy than his brethren, so he doesn't go in for the overdramatic Kneel Before Zod stuff when he knows it's not the best means of getting what he wants, but that doesn't make him less evil in the slightest, even if, yes, he's willing to work with an enemy to save his own butt. When he was on Earth, he (and his pal Athena, who was never caught) arranged for a building to be laced with naquadah to be used as a bomb. Imagine a nuke the size of the Empire State Building. The first encounter with him?*
Technically, we first saw him standing around in the background during the "Summit" two-parter, but this is when he first did something.
He took advantage of the sarcophagus' nigh-magical healing ability and tortured O'Neill to the point of death over and over, refreshing him to start up a new session. Not that you get the feeling that they'd treat him any better if he wasn't a threat to the whole galaxy... but he is.
The living Ancients in the Stargate Atlantis episode "The Return" fall squarely within this trope. After their hyperdrive failed in the void between the Milky Way and Pegasus, they set their ship up to travel at .999 percent the speed of light. Thanks to relativity, they're still alive 10,000 years later when the Atlantis expedition finds them and brings them home. Their thanks? Kicking the entire human population out, including the people on the mainland, so they could be "alone" and have "time to adjust". Despite repeatedly stating their gratitude, they never actually show it. Arguably they could have had a chance had they not been killed within weeks of reclaiming the city, but there's really no excuse for just how unreasonable they were behaving at the beginning.
The Coalition of Planets that puts Sheppard's team on trial definitely counts. They made some good points (the same points the fandom made about their numerous What the Hell, Hero?-worthy moments, in fact) but, as Sheppard pointed out, the Atlantis team is the only thing standing between the Pegasus galaxy and total domination by the Wraith (or Michael.)
In the M*A*S*H episode "Of Moose and Men", Hawkeye saves the life of a Colonel who is angered by his unmilitary bearing and lack of discipline. After the operation the closest he can come to thanking Hawkeye is to tell him he's "letting him off the hook" (as a favor to Colonel Potter, not Hawkeye himself) by not having him court-martialed for insubordination.
In another episode, Hawkeye saves the life of a North Korean spy, who curses him for weak and vows to fight him someday.
In Misfits, when Nikki receives a heart transplant that saves her life, she tells the doctor she doesn't want her new heart, and orders him to take it out and give her a different one. In her defense, along with the new heart she had inherited the "gift" of spontaneous teleportation (her first trip resulted in her finding herself in the morgue, lying on top of the frozen corpse of her heart donor) but she couldn't really tell the doctor that part without sounding batshit crazy.
As shown on the quotes page, in the Victorious special Locked Up!, Tori protects Jade from a prisoner who was threatening her. Jade's response: "I didn't need your help!" Which is an interesting perspective considering that said prisoner just knocked Jade to the ground with one blow.
In the Doctor Who episode Full Circle, one character doubles back and pulls another free from the marsh men, and is caught himself. The rescued one takes one look at his rescuer and runs off without even trying to help.
In Crossing Jordan Garret Macy found out that a dead victim is alive and paralyzed near death, said victim happens to be his old friend who sets his life in ruining the entire cast. When he was paralyzed he said in his mind that he would change as a better man if they saved his life. But when he got out of the hospital he decides to sue the team for negligence. On the way to his car he was killed for real when he was hit by an ambulance.
Ingrid in Young Dracula, especially in season three. She's trying to distract her brother so one of her vampires can kill him. She decides the appropriate distraction is to thank him for when he saved her life the previous episode.
Jack Bauer in 24 has personally saved the USA government officials from political assassinations, a false pretense for war, nuclear attacks, biological attacks, a corrupt president, and more.. To thank him, the officials he worked for don't do a damn thing to save Jack when he was captured by Chinese agents who tortured him for almost two years for information (that he never gave.) Also, most of 24 consists of bureaucrats putting all their efforts in punishing Jack after or even when he's stopping terrorists from murdering hundreds of thousands of people. After everything he's done to save the country, the country's leaders give him less than squat back.
Sophia from the Merlin episode, "The Gates of Avalon". As one of the Fair Folk forced into the body of a mortal woman, Sophia was not at all pleased when Arthur (whom she enchanted into falling in love with her) saved her from a raider attack. In fact, she was enraged that she had been lowered to a state where she had to be rescued by someone far less powerful than she had been and still plotted to kill Arthur so she and her father could return back to Avalon.
Arthur in the earlier seasons was completely unwilling to thank Merlin for his help or his advice. Nowadays, he's much more grateful, to the point where Merlin is practically Arthur's unofficial advisor and everyone knows it.
Elliot of Scrubs very much qualifies with her behavior towards Dr. Cox in later seasons. In a few episodes, Elliot would rant at Dr. Cox about how he has never helped her. Not counting that he helps her in all of these episodes and other times, he punched out the CHIEF OF MEDICINE for her, risking his job.
Nina is this to Fabian MANY times on House Of Anubis, most notably when he rescues her from falling into the chasm.
Fabian: I...I saved you...
Nina: Oh yeah? Well why don't you save the other girl (Joy Mercer) in this dress?!
Fabian has also tended to be like this towards Joy in season 3.
Also Rufus Zeno. Patricia had taken a huge risk and rescued him from the hospital when the teachers had put him into some sort of coma, and he repayed her by kidnapping her later on.
The captain of the Golden Vanity promises the sky to whoever sinks the enemy ship (French or Spanish, depending on who's covering), then goes back on his word when the cabin boy succeeds, refusing even to pull him back on board. Some versions have the kid surviving, most not.
The Bible – particularly the Gospels – contain many parables and passages about gratitude:
Luke 17:11-19 is the story of Jesus cleansing 10 lepers, but only one of them – a Samaritan – thinks to thank Jesus and praise Him. While Jesus has plenty of praise for the one who did show his gratitude, He is highly offended at the nine who didn't: "Were not 10 cleansed? Where are the nine? Was no one found to return and give praise to God except this foreigner?" And He said to him, "Rise and go your way; your faith has made you well."
Matthew 18: 21-35 tells the story of the unmerciful servant. Here, the ruler of a kingdom demands that a lowly servant repay all his debts – 10,000 talents, equal to a lifetime of wages – immediately or face imprisonment and torture. The servant begs for mercy, which moves the king enough to cancel the debt. Not long thereafter, the servant encounters one of his friends, who owed him a small amount – stated in the Bible as 100 denari, or less than an average day's wages. Likewise, the man's friend says he doesn't have the money and asks for time to collect money to repay the debt, but the servant refuses to accept the explanation and has him badly beaten. The king learns of this incident, summons the servant and screams at him, "You wicked servant. I canceled all that debt of yours because you begged me to. Shouldn’t you have had mercy on your fellow servant just as I had on you?" Jesus – who again weaves this parable – then explains that the king had the servant jailed until the debt was repaid. His entire point was that good Christians show mercy and gratitude.
Matthew 20:1-16 is about laborers in the vineyard. Here, the owner of the vineyard hires workers in stages, paying them all an identical sum at the end of the day, regardless of how many hours they worked, whether for several hours or just a few minutes. The workers who received their denarius for working only a short time are thankful, but those who worked all day in scorching heat and without breaks complain when they are given the same denarius. The master, sensing that his worker(s) are ungrateful for what they view as meager pay, replies, "Friend, I am doing you no wrong. Did you not agree with me for a denarius? Take what belongs to you and go. I choose to give to this last worker as I give to you. Am I not allowed to do what I choose with what belongs to me? Or do you begrudge my generosity?" Jesus' point, aside from gratuity, is one He makes several times in the Gospels: "The last will be first, and the first last." (Matthew 20:16).
Good god, Phantom Brave. Most of the population believes Marona is "the Possessed One" who can kill them all. So not only do they berate, insult, and hiss at her...they hire her services to save their bacon, and then stiff her on the payment. They get better, but geez.
Kohaku from Tsukihime is a rare somewhat-justified example of this trope. As an eight-year-old child, she was repeatedly and violently raped by Makihisa Tohno so that Makihisa could take advantage of Kohaku's "Synchronizer" ability to help keep him sane. When Akiha discovered what was going on she put a stop to it immediately, but Kohaku still sets a plan in motion to destroy the Tohno family, wiping out Akiha as well and sparing only the (adopted) Shiki. But this isn't deliberate ingratitude on Kohaku's part; in order to mentally survive repeated rapes, Kohaku killed off her emotions and became a doll, so she tried to destroy the Tohno family just to give herself a purpose in life, not out of a spiteful desire to destroy her rescuer Akiha.
The fairies in Chrono Cross. After saving them all from certain death by rampaging dwarves, they yell at you for happening to be humans. The dwarves blamed the humans for killing their marsh, but instead of going after them killed people nominally on their side. Yet Serge's party is the one who takes the blame, even for killing the dwarves who were attacking!
The fairies are a prime example, but really, EVERYTHING in the game that accuses Serge and company of wrong doing is full of itself. Especially the Green Aesops toward the game's ending. The dwarves get on Serge for killing the Hydra. Said dwarves are also the guys who have been trying to kill you, no questions asked, since you got into the Marsh. Then said dwarves go off and slaughter the fairies. Save the fairies, and they act like you're the murderers. Then there's the whole "Reptites evolved more closely with the planet!" Which is a load of crock, since the Reptites were building giant castles and actively waging war, while the humans had been peaceful, and lived in harmony with nature. Nevermind the parts where the dragons try and blame you for Lavos' crimes. Chrono Cross takes place in a WORLD of ungrateful bastards.
Scott Shelby a.k.a The Origami Killer from Heavy Rain can be this in one of the scenarios played out. During the fight on a conveyor belt against Jayden. If you did the button prompts right, Shelby gets knocked off and hanging for his life. You can choose to let him drop or hoist him up. Choose the latter, and he still tries to kill Jayden. Not surprisingly this leads to Shelby's downfall after one last struggle.
The weeping willow in King's Quest V: Absence Makes the Heart Go Yonder. When you turn her back into her human form, she carelessly tosses aside her harp (the sole comfort she had the whole time she was a tree), calls her fiancé, and struts off with him without so much as a word of thanks to you. As Paw Dugan put it in his Let's Play, "YOU'RE WELCOME, YOU UNGRATEFUL BIIIIIIIITCH!!"
Moore served in Operation Sunburst a few years prior, which saw the NCR and Brotherhood in a state of open war and in which the NCR incurred massive casualties before wearing the Brotherhood down via sheer weight of numbers. Her unhappiness over an alliance with them is understandable, even if not exactly agreeable. Likewise, the Great Khans boast about their open antagonism towards the NCR and although they've fallen on hard times lately, even a cursory look at their recent past paints them as little more than opportunistic raiders who killed and stole whatever they pleased. A former Great Khan who was present at the Bitter Springs Massacre even says the tribe got what was coming to them.
It may seem reasonable at a glance but Word Of God confirms she's only motivated to get rid of my by personal vendettas. And again, she claims they're a big enough threat that they need to be take care of... But expects one person to single handedly kill every last one of them.
Also, if the NCR achieves victory at Hoover Dam, Moore gets herself promoted to Brigadier-General by taking credit for all of the Courier's actions, unlike Colonel Hsu.
In Dragon Quest VI, even after you weaken Murdaw by defeating him in the dream world and, you know, saving the monarchs of Somnia from certain doom, the guards of Somnia will still treat you like a piece of shit due to the events of your last visit. Thankfully, the recently awakened king sets them straight before things can get hairy.
At the end of Crash Twinsanity Dr. Neo Cortex learned from his mistake and goes back to being Crash's arch rival.
Miles Edgeworth comes off as one to Phoenix Wright in the first Phoenix Wright: Ace Attorney game. When things look hopeless for him while he's on trial for murder, Maya manages to coerce Lotta into making a contradiction with her testimony by shouting out at her, getting held in contempt of court in the process, but in response, after the first day of the trial, Edgeworth tells Phoenix she should watch what she says in court. This is ultimately subverted when it is revealed that Edgeworth arranged to pay for Maya's bail. Gumshoe also notes that Edgeworth's lips were trembling during the outburst.
Lana Skye also comes off like this when she actually tries to confess to murder and fire you from your position as your attorney, but she has a decent reason because she thought your continued defense would implicate her sister Ema.
Knight Commander Meredith in Dragon Age II. Even if you side with her during The Last Straw, she will still try to kill you. Also Grace, the apostate mage that you help earlier in an Act I quest, returns in Act III convinced that her own failure to escape the templars is your fault.
In the previous game, you rescue Queen Anora from Arl Howe's estate. On your way out, you're confronted with Ser Cauthrien and a number of guards who charge you with breaking and entering and murder of the Arl. You'd think having the captive Queen on hand would get you to get out of the situation without bloodshed, but drop her name and reveal her and she instead pins her kidnapping on you and your companions.
No, that was necessary. She even explains why the ruse after you return.
First Enchanter Orsino's a milder example than Meredith: even if you side with him during The Last Straw, he still snaps out of sheer despair and transforms himself into an abomination that you must then kill. He's milder than Meredith because he does seem grateful at first that you sided with him, while if you side with Meredith she still acts like she barely tolerates you, and then singles you out for supposedly "betraying" her, while Orsino merely attacks everyone indiscriminately after his transformation.
Fenris is like this at first after you help him in the "Bait and Switch" quest because he's distracted by the (possible) presence of mages in your party, but then he catches himself doing this and says, "I imagine I must seem ungrateful", and then he thanks you properly.
He has the potential to do this again, in his personal quest during Act 2, if Hawke is a mage: "What has magic ever touched that it doesn't spoil?" The look Hawke gives him in response to this says volumes. (And as before, he drops by your house to apologize.)
The Council of Mass Effect certainly acts like this toward Shepard. Virtually any major decision in the first game will be second-guessed by them, even actions carried out by a force you had no authority over.
Carries over to the second game. The original Council, which owes you their lives, refuses to believe the Reapers exist and only grudgingly gives you your SPECTRE status back. If it's the human council, who owe their position to you, they won't even speak with you and only Anderson can get you reinstated.
In the third, you'll be surprised that Shepard doesn't name this trope. Council Tevos's Exact Words are:
The cruel and unfortunate truth is that while the Reapers focus on Earth, we can prepare and regroup.
Subverted in the third, however, if it's the "replacement council" you get in Mass Effect 3 if you sacrificed the Mass Effect 1 Council. Like the original council, the replacement council refuses to help—but they actually have a good reason, because they don't trust that a Shepard who was willing to sacrifice the previous Council to advance human interests might not do so to them if given the chance.
Additionally, both the original and the replacement council were caught off guard by the Reaper attack (granted, they didn't believe you, but it's hard to expect them to just take your word for it), and the theoretical plans for using the Crucible (not even Liara knows what the Crucible can do, or what the Catalyst is).
There are several demons who will allow you to begin negotiations with them, ask them to be your demon, make demands of you... and then refuse to join you anyway. These demons are all of either the Law or Chaos alignments (they include Angel, Oni, and Lilim), and will not pull this on you if you're of the same alignment. Thankfully, there's a Sub App called "Tea Amity" that forces them to reconsider their refusal; once they reconsider, they will always agree to join you.
At the End of Saints Row The Third if you rescue Shaundi, she berates you at first asking why he lets so many of his other friends die. She gets a cold "Shut Up" from The Boss afterwards showing that he really took that personally.
In FTL Faster Than Light, it is possible to ride to the rescue of some harassed ship only to have it jump away without offering anything as thanks.
Civilization IV: It doesn't matter how much technology you share with Tokugawa, how many of your units you donate to him, or how many of your resources you gift to his civilization - Tokugawa is such an isolationist that he won't even open his borders, let alone give you anything in return.
Queen Therazane in World of Warcraft Cataclysm. Despite helping her get rid of the Twilight Cult presence in her Deepholm, she never actually likes The Earthen Ring, with her outright telling them, after they repair the World Pillar (which was actually broken apart by Deathwing during "The Shattering"), that they aren't welcome there (The Earthen Ring do oblige that without objection). However, the player character, once completing the last story quest in that zone, is welcome to stay (which is a bittersweet reward: though you gained her respect and welcome, Therazane is also home to what was one of the most grueling Daily Quest grinds in the Cataclysm expansion...which was a necessity since they held the all important shoulder enchantments. Thanks a lot, Queen).
Much of this hatred stems from players killing Theradras, her daughter (the last boss of Maraudon, and a boss in the Elemental Invasion event), but one would think that she would be at least somewhat grateful for saving the entire Plane of Earth.
She might've liked Thrall, though, despite his involvement with the Earthen Ring, though. She seemed to be sympathetic of his issue of the elements being separated from him in patch 4.2 when you helped Aggra get him back, though it seems as Aggra didn't exactly forget how ungrateful Therazane was to them earlier if you take what she says in Vash'jir just prior to you and her going into Deepholm to save the former Horde Warchief into account.
Magatha Grimtotem, after being rescued from the Twilight's Hammer cult, implies she will kill you if you meet her again.
Shirogane Sakuya is unwittingly this to his despised half-brother Sakazaki Yuuya in Hatoful Boyfriend. It's because of Yuuya that Sakuya is alive and was raised as a noble.The Reveal in BBL, coupled with Yuuya's Heroic Sacrifice, sends him into a Heroic BSOD as he thinks on this trope with deep shame. Sakuya never knew he had something to be grateful for, and he had scorned and derided Yuuya at every turn for being a "mongrel".
Sakuya is a shade better about this in Holiday Star. While he has nothing but disdain and anger for everything Yuuya does in most of the game, at the end he very grudgingly says that perhaps Yuuya's efforts had some worth. Yuuya, well aware of what his brother is like, is touched and says that makes it all worthwhile.
Played for laughs (at the player's expense) in Nie R. In one sidequest, you need to find a man's son, who has run away from home and refuses to take up the family business. You chase the kid down, get tricked into finding vendor trash for him, find that he's left again, talk to his father, discover that he's run off to a desert town, get tricked again and let him escape, chase him across the desert and (at last) convince him to go back to his family...who then leave before you can talk to them. It turns out that they were criminals, and the kid wanted to get away from "the family business. And the kicker? You don't get any reward except the knowledge that you just returned the kid to a life of crime. Nice job breaking it, completionist.
In Bad Machinery when Archie saves Linton from drowning he comments that it probably only saved him so it could kill him itself. Jack then claims to be phoning the dictionary to ask for a stronger version of the word "ungrateful".
MeatShield: Prince Jonus of Westhame. After they saved his sorry life and soul from a demoness and a bunch of evil cultists, he has the gal to try and get the heroes arrested for "laying a hand on his person". Jaine's response sums it up best.
Zuko was an Ungrateful Bastard pre-Character Development. Aang saves his life twice in the first season (though the first may have been a simple qui-pro-quo since Zuko freed him) and once in the second season. His uncle even points out to him that he's only alive because of the Gaang's mercy, but he still chooses to help bring him down in Ba Sing Se.
Early in season two, Zuko was on the receiving end of this trope in "Zuko Alone". He comes into an Earth Kingdom town as The Drifter, stands up to the bullying soldiers oppressing them, and saves the kid who hero worshiped him, but because he does the last bit after revealing his identity, the entire town, including the kid, shuns him.
Early on in the first season episode "Imprisoned", there's an Earth Kingdom village being occupied by the Fire Nation, which outlaws all earthbending. While Katara is talking with Haru, an earthbender who practices in secret, they find an old man who is trapped in a landslide. Haru saves his life using his earthbending, only to be repaid by the old man turning him in to the Fire Nation.
Thankfully averted in the third-season episode "The Painted Lady". After Katara (who has been masquerading as the eponymous spirit) drives the Fire Nation army away from the town and blows up their factory, one of the townspeople recognizes her. The rest of the town gets mad and it looks like they're going to get run out of town, only for Sokka to step in and yell at them about how ungrateful they're being, since the factory is destroyed, the army is gone, and the people can make their village prosperous again.
Commander Feral in SWAT Kats has been personally saved by the SWAT Kats dozens of times, as well as seeing them save the city. This does not change his opinion that they are dangerous vigilantes who should leave protecting Megakat city to The Enforcers.
"The Dark Side of the SWAT Kats" features what might be an amazingly fitting inversion involving the same character. When the SWAT Kats find themselves in a Mirror Universe where their equivalents are evil, they plead with Feral to check out Pumadyne labs to see that a bomb detonator was stolen by that universe's evil SWAT Kats. He comes to believe them enough to check it out, and when the evil SWAT Kats show up and attack, admits they were telling the truth. He still thinks the Enforcers can handle it alone, though; and he might have a point, in a setting where a lone Enforcer helicopter reacts to animated skeletons by casually obliterating them with Gatling fire.
This is possibly justified by Feral's rigidly Black and White view of justice. In "Metal Urgency", he refuses to let the Metallikats tell them who the SWAT Kats really are. When Callie Briggs calls him on this, he simply says he won't deal with criminals on any level.
It's not like Feral's wrong. The SWAT Kats have massive firepower, cause huge amounts of collateral damage, refuse to follow the rules and are generally reckless. (Example: in "The Giant Bacteria" they dropped Morbulous because it was more fun than just handing him over, thus allowing him to escape before the Enforcers could get him again.) And he's not completely ungrateful, he just greatly disapproves of them and their methods, and you can pretty much tell which episodes he'll be sympathetic/grateful to them because they'll add in a different character to take up the unsympathetic role.
Feral didn't like them when they were Enforcers either: on their first day (as shown in "The Wrath of Dark Kat") they saved the city but destroyed Enforcer HQ, which got them fired and on Feral's blacklist for life.... Which wouldn't have happened if he hadn't interfered in the first place.
Good guys even show signs of this on occasion, like Robin did in the "Tournament of Heroes" episode of Teen Titans. In the three-way fight between, himself, Speedy, and Wildebeast, Speedy helped him defeat Wildebeast; only for Robin to hit him with an explosive device. (He did say "thank you" first, however.) in Robin's defense, neither he nor anyone else (except Cyborg) realized that this was a Deadly Game in disguise (not literally, but it was similar, so you could say he was just being competitive.
The FOX 90's Spider-Man The Animated Series. JJJ has a Freudian Excuse for hating Spidey and every other masked character (except Scorpion, whose creation he personally endorsed): his family was killed by The Rose, a mask-wearing mob boss that (in main Marvel continuity) was a subordinate of The Kingpin.
Just to be clear, Jameson isn't fond of Scorpion either. It only took about half of his origin episode for JJJ to realize he screwed up, and he even goes so far as to admit that Spider-Man is the lesser evil of the two.
In one episode, this is subverted. At the end of the episode, after a plot that Nick Fury and S.H.I.E.L.D. had to recruit Jonah's help for, Spidey has saved the day, caught the Chameleon, but no-one has even said thank you. Jonah is probably going to profit from the whole episode by printing an issue that will likely sell out (no doubt blaming him for it all). As Spidey sulks on the roof of a building, wondering if it's all worth it, Fury flies by in a high-tech vehicle, shouting to him, giving him a heads up and expressing his thanks for the help. Spidey is a little surprised that someone actually did that, and figures that at least it's a start.
In the animated version of The Legend Of Zelda, Zelda comes across this way with her continuous refusal to kiss Link even after he saves her life/father/kingdom repeatedly. Granted, he has a tendency to request the kiss when they're not yet out of danger, but even after the threat has passed she often comes up with stupid reasons not to do it.
This one might be justifiable, though; she might not kiss him simply because she might not be interested in him in this continuity. Now why she doesn't give Link a reward besides a kiss, on the other hand...
This trope was the whole reason Mona Simpson was always on the run from the law. After saving Mr. Burns when a hippie demonstration she was participating in went wrong, Mr. Burns was able to identify Mona, forcing her to abandon Homer at such a young age. Luckily, the demonstration had also cured a young Clancy Wiggum, who was working as a security guard, of his asthma. Unlike Mr. Burns, Wiggum was, in fact, grateful because it finally allowed him to join the police force, and he anonymously helped Mona escape from Springfield to avoid getting arrested.
Sideshow Bob still tries to kill Bart, even teaming up with his brother Cecil on one occasion, despite that Cecil previously tried to kill them both and it was Bart who saved him.
In the episode "On A Clear Day I Can't See My Sister" Lisa serves Bart with a restraining order and using it to bully him. Eventually forcing him to eat his lunch outside in the rain, be taught by Groundskeeper Willie in a tool shed, and sleep on the edge of the property. At one point Lisa says if she can remember three moments where Bart was nice to her, she'll lift the restraining order. She thinks as hard as she can, and can only come up with two, both of which only came from that episode. The problem is most fans could name three off the top of their head (Lisa It's Your Birthday, the Hockey episode, and buying Bleeding Gums Murphy's record for her), heck the episode "Separate Vocations" shows us that Lisa wouldn’t even be going to school if it wasn’t for Bart.
Elise's parents, though her mother is a bit less. Despite the fact that he saved their lives, neither of them really like Chris. Dan also saved their life on a separate occasion, but their hatred of him is somewhat more understandable.
Rigby:What a windbag!, I thought he’d never shut up. I can’t believe you guys thought he was me. You must feel like idiots, right?
Gobsmack from Pearlie is the pickiest bastard in the show.
After the mutual Revenge Romance between Brian, Quagmire and each other's exes on Family Guy, Brian apologizes to Quagmire for his behavior and offers to bury the hatchet in hopes of finally becoming friends. Just when it looks like Quagmire, who has had a known dislike for Brian, has finally let it slide, and he is about to agree to Brian's request for a ride home, only to drive off before Brian can get in, and then hit Brian in reverse. What a creep!
Gargamel the wizard in The Smurfs. Despite many a Save the Villain moment by the Smurfs, he still never returns the favor and is still plotting his revenge against them. Even his cat Azrael, when Natural Smurf shows him mercy, is that ungrateful.
In My Life as a Teenage Robot, Jenny is kicked out of a popular teen hangout because Mezmer, the owner, refuses to serve robots. Later on, she saves the shop from a gang of space bikers. Mezmer still kicks her out, but this time, the rest of the teens, who were grateful that Jenny saved them, leave as well.
In Transformers Prime, Silas' subordinates save him from certain death by installing him in Breakdown's body. Silas is pleased with the results and thanks them for a lifetime of service. Then he casually murders them so he can join the Decepticons.
In the episode "Babel" of Batman Beyond, Terry saves some zookeepers from some escaped animals. Later, when Shriek makes the whole city unable to understand each other, the zookeepers are among the people demanding that Terry turn himself in.
In one episode of Teenage Mutant Ninja Turtles 1987, the Turtles are being badmouthed on air by a Jerkass talk show host which has been doing well at turning the public against them. By the end of the episode they manage to save his life from Krang and are pretty sure that by now he'll soften up. Nope, he's going to be trashing them even more than ever! After all, it may not be personal, but it is what brings in the ratings. The Turtles are understandably pretty ticked.
Sponge Bob Square Pants, of all people, becomes one of these in the infamous episode "A Pal For Gary". After scolding and blaming Gary for Puffy Fluffy's actions throughout the whole episode (even when the now-monstrous Puffy is CLEARLY trying to eat the snail), he is grabbed by Puffy and nearly eaten himself. At this point, Gary has every reason to just leave Spongebob to his fate, but instead of doing so, he shows an incredible amount of loyalty and courage, and whips Puffy to knock Spongebob out of his mouth and drive him away...and instead of thanking Gary, or even apologizing for his earlier actions, Spongebob a) tries to get Puffy Fluffy back, and b) after that fails, scolds Gary AGAIN!
Psychopaths are psychologically and neurologically incapable of feeling grateful, so it's no surprise that they often forget (or just don't care enough) to feign gratitude.
On a national level, many Canadians have felt this way about US politicians due to 9/11. Despite the country accepting all the international flights diverted from the US (and thus assuming the potential risk of terrorists arriving on those flights, when no one knew what was going on or how many there were), it was noted that when the Bush Administration was going around thanking other countries for their support it took days before they remembered the country next door. The continued exasperation at the Canadian embassy having to send out regular press releases informing candidates, elected officials and even cabinet members that, no, none of the hijackers entered the US from Canada, merely adds to it.
Oriana Fallaci. She was an Italian journalist who got trapped in the middle of a shooting in Tlatelolco, Mexico City and was shot three times before she was left for dead. By the final years of her life, she hated Mexicans even though it was thanks to a Mexican that she survived. The Mexican student standing beside her protected her with his body from the bullets that were impacting everywhere before he was arrested (and probably tortured).
The family of Hank Gathers (Loyola Marymount basketball player that died on court in 1990) attempted to sue both of the first responders that attempted to help their son, and they sued the school as well. The lawsuit against the first responders (including a doctor in the crowd who volunteered to come down and help) was unsuccessful. The lawsuit against the school was settled out of court before trial for 1.4 million.
North Korea, whose sole supply of almost all of its needed goods comes from China, often insults them and isn't very thanking.
For most of its history North Korea depended on foreign aid from Communist states to keep the economy running. However, this was never officially acknowledged. The Soviet Union ignored this ungrateful behavior because they needed North Korea as a buffer state and did not want them to ally with China. After the Soviet Union collapsed North Korea suffered economic disaster as Russia and China began demanding that any payments be on time and all friendship prices were revoked.
One of the most important things your learn playing online games, especially a MOBA? That there are tons of these - and when you aren't playing with an Entitled Bastard? You're playing with one of these.
A.I.G., who is now considering suing the US federal government after the government gave them a $182 billion bailout during the financial crisis and saved them from the trash heap, because the Feds took a 92% share in their company until A.I.G. could pay them back.
Everybody, ever, who put extreme effort into making someone happy, or being in their life and ended up getting rejected, ignored, or the person just leaving for no good reason. So basically everybody (at some point, anyway).
