A Frozen Heart, a tie-in novel to Disney's Frozen, introduces the King of the Southern Isles, the abusive father of Prince Hans. While Hans himself commits actions that are inexcusable in the film, this novel depicts him in a more sympathetic light by comparison. His father is an emotionally abusive and sociopathictyrant who is feared and widely despised in his entire country for destroying homes and arresting (possibly killing) people for not providing enough favors or criticizing him. He's also shown to be an abusive spouse to his wife, who is left in a fragile state due to years of childbirth. Except for Hans, who decides to become his gofer as a way to escape home for good and harbors little to no loyalty to him, most of his sons are all heavily loyal to him and do what he asks, though it's implied they act out of fear as he despises any form of compassion or kindness. He exists solely to make Hans look tame in comparison.
Ancillary Justice has Seivarden Vendaai fill this role in the first part, before the main villain is introduced. She's from a rich noble family, treats everyone else like they're dirt under her feet, and when, at the start of the novel, she has lost everything and has to be rescued by Breq, she's still insufferably arrogant and refuses to do any work at all, until Breq makes it clear she won't tolerate this behavior. After Breq saves her life by jumping down a bridge from which Seivarden has fallen out of sheer stupidity, and breaks all the bones in her own body just to save Seivarden, Seivarden gets a bit more tolerable. The reader doesn't so much want to see Seivarden fail (at this point, Seivarden does not have any goals, unless you count the next drug dose as such) as she just wants Breq to get rid of her and continue her journey alone.
Arc of a Scythe: Among the New Order Scythes introduced in Thunderhead, Scythe Brahms is the most unlikable. He's a slimy, lazy, cowardly Scythe who kidnaps and psychologically tortures his gleaning targets by playing Brahms' Lullaby before gleaning them. When Rowan targets him and tries to force him to change his ways he instead goes on to be worse. He throws his lot in with Scythe Rand and aids her in her plan to try and kill Scythes Anastasia and Curie in order to make Goddard the MidMerican High Blade. He gleans Rowan's father, forcing his whole family to listen to the Lullaby and it's clear that he will continue to glean his family. He lures Rowan into a trap so Rand and Goddard can get their revenge on him by executing him in front of the World Scythe Counsel. This is all in tandem with him being a Jerkass who lets his dog crap on his neighbor's lawn and tries to solicit Rand for sex under the pretense of comforting her over Goddard rejecting her.
Mr. Poe of A Series of Unfortunate Events may be well-meaning and sympathetic to the Baudelaire orphans, but his utter incompetence is enough to make both the orphans and the audience groan with frustration. He constantly falls for the villain Count Olaf's obvious disguises, treats the Baudelaires like toddlers, and repeatedly puts their safety at risk due to not being able to see through Count Olaf's plans. It says a lot about him, as well, that he once delivered the Baudelaires to another guardian (who, obviously, is killed soon by Olaf) and the only thing that mattered to him to choose to take them there was not the guardian's potential competence or anything similar, but merely that the guardian was the closest option at the time.
Joffrey Baratheon himself fills this role eminently by being the most vicious and abusive little Royal Brat in a series full of them until he's killed in the third book. Even In-Universe, only Cersei mourns his death.
Walder Frey, who makes no attempt to hide what a degenerate, vile scumbag he truly is to everyone around him. The only reason people continue to tolerate him is because he holds an important strategic point between the North and the Trident. When he and his family commit the most appalling and most craven of crimes by breaching the Guest Right, everyone except the Boltons and Lannisters (who are already both extremely hated by that point) in the continent wants to see him and his entire family dead. In fact, it seems, Tywin planned on the Freys being an in-universe Hate Sink from the get-go. While people understood Tywin engineering the Red Wedding because he was at war with the Starks, they loathe Lord Frey and his family for carrying out Tywin's plan, because, by doing so, they broke one of the most sacred laws of the realm.
Ser Gregor Clegane, "the Mountain that Rides". He's a Blood Knight known for his cruelty and brutality, who enjoys torture, murder, and rape, to the point he has the Fan Nickname "the Mountain that Rapes". He also kills Ensemble Dark Horse Prince Oberyn Martell when Oberyn tries to avenge his sister, who was raped and murdered by the Mountain. Fortunately, Oberyn hadthelastlaugh.
Liane Moriarty's novel Big Little Lies has a host of antagonists, yet most are portrayed as too complex to be considered truly despicable. The one character who has absolutely no redeeming factors is Renata's sycophantic elitist friend Harper. Harper attempts to turn the whole school against one of the main characters and her son for supposedly attacking Renata's daughter, despite not having a single scrap of evidence. She obviously believes that she'll come across as a crusader for justice, but ultimately she just seems like a drama-hungry shrew.
In The Cat Ate My Gymsuit. Marcy's Father is a terrible husband who constantly fights with his wife Lily to the point where she appears to be taking drugs to cope and is abusive to his two children, calling his teenage daughter fat, stupid, and ugly (leaving her with severe self-esteem issues as a result), and harshly scolding his four-year-old son for sucking his thumb and playing with his teddy bear. It's quickly obvious to the reader that he doesn't even like, let alone love his family. Especially when Marcy tries to get her family to sit around the dinner table and discuss things like a normal family, her father's response is, "I work hard all day for this family, I don't have to talk to all of you too, do I?" as if talking to his wife and children without screaming at them is a strenuous chore. He also uses Marcy as a scapegoat for nearly everything that goes wrong in his life, including Lily spending less time with him and more with their children, his fighting with Lily that he always initiates, and Marcy's attempt to initiate a simple family discussion going horribly wrong. One has to wonder why he decided to get married and have children in the first place if he hates having a family so much, outside of a possible Shotgun Wedding. From start to finish, he has zero redeeming qualities and it's obvious that he's meant to be despised by the reader more than any other character. The only good thing that can be said about him is that by the end of the book, he's been convinced to more-or-less leave Marcy alone and has achieved an uneasy peace with her, but he's still far from being any kind of family man. The ending shows Lily is starting to stand up to him and making a life for herself, foreshadowing the possibility she may hopefully leave him and take Marcy and Stuart with her.
The Children of Húrin: Saeros is a racist Elf in King Thingol's court who resented the presence of Turin as a ward of Thingol. One evening Saeros made insulting remarks about Turin's people, causing Turin to injure Saeros. The next morning, Saeros attempted to murder Turin over the last night's events, provoking Turin into stripping him and accidentally killing him by running him off a cliff. When Thingol heard of what Saeros had done, he pardoned Turin, while it was stated that Saeros would be held in Mandos, the land of the dead, for a long time due to his misdeeds.
While some Chris Crutcher novels have outright villains and others don't, a consistent presence in all of them is a Hate Sink character, typically taking the form of a smothering, close-minded authority figure who restricts the personal freedoms of the teenage protagonists in some manner. Examples include the Smug Snake assistant principal in Staying Fat for Sarah Byrnes who deliberately engineers conflicts between students he doesn't like so he can punish them both, the jingoistic, hypocritical history teacher in Deadline, and the heroine's authoritarian, uncaring adoptive father in Losers Bracket who wishes to completely isolate her from her biological family.
Cthulhu Mythos: The Defiler is one of the few of his kind that can be regarded as truly evil, being a cosmic Serial Rapist and Serial Killer that has absolutely no problems with defiling and murdering anyone he gets his hands on.
In Deadhouse Gates, the second book in the Malazan Book of the Fallen, the Chain of Dogs (a massive host of refugees marching across the continent) is constantly being attacked by enemy armies, but our viewpoint character for these sections of the story never gets more than a few glimpses of the enemy leaders. Without a face or personality to put to them, it's hard to dislike the armies of the Apocalypse on a personal level. Instead, we're invited to vent our loathing upon a group of whiny nobles within the Chain of Dogs, who protest the commander's actions at every turn, are openly cruel to their servants, and get a lot of their fellow refugees killed through incompetence.
Dragon Bones has high king Jakoven. The heroes never meet him in person, but we get to see how he regularly appoints men to become Queen Tehedra's lovers, then kills them for petty reasons, are told that he sleeps with young males, who may be underage, and took a fifteen-year-old boy, whose parents were killed by his soldiers, to his bed. The man, now thirty, secretly detests him. Oh, and one of the Queen's lovers he kills is a cousin of the protagonist. He also refuses to send soldiers to defend one of the countries under his rule, in the cold-blooded tactical plan to take care of the invasion/bandit problem only when it starts to get closer to his home. The actual villain, i.e. the one who needs to be fought by the heroes, is a rather cool Smug Snake, and not nearly as hateable as king Jakoven.
Ephemeral Prince has Rizec, who performs several vile actions such as destroying the original Sabine out of spite for its rulers, ordering Zuan to trick Soan into eating Xiri, subjugating the demons, setting a trap for Snowe's party, and killing Hiante. The first two actions resulted in the Starts Of Darkness of all the prequel's villains and indirectly caused most of the problems in the series. He feels no remorse for his misdeeds, to the point where he gloats about how he spared the rulers of Sabine in order to make them suffer more and how he could potentially force Xiri to kill his own home.
Et je prendrai tout ce que j'ai à prendre, by Céline Lapertot: Charlotte's father, beneath his loving facade, is in truth a narcissistic pervert who abused his own wife Mathilde so much he turned her into a Broken Bird before the story even starts. Introduced giving Mathilde a No-Holds-Barred Beatdown because he had a bad day at work, he punched his daughter Charlotte and locked her up in the cave because he felt his control over her was slipping. The cave became Charlotte's bedroom for 10 years, during which her father constantly abused her, threatening her into not saying anything to her grandparents in a fatherly tone, beating her up and ripping to shreds one of her books when her grades worsened, or forcing Charlotte to watch as he destroyed her old bedroom (that he constantly changed to fit Charlotte's tastes). When Charlotte befriended Guy, her father found out, and attempted to rape her when she had shown the slightest bit of defiance.
Since there's no real villain in Flight 116 Is Down by Caroline B. Cooney, the audience gets to focus their hatred on Darienne, a selfish passenger who ends up being completely unharmed in the crash. Heidi and Patrick work hard to save the passengers of the crashed plane while Darienne stands around doing nothing but complaining and being useless, yet she tries to take credit for saving people at the end. Even Patrick loses his cool when Darienne gets too much to handle.
Flip-Flop Girl. Has Vinnie's mother and grandmother, although they mean well most of the time, they cause most of the problems in the novel by completely neglecting Vinnie in favor of her younger brother Mason because they believe he's been traumatized into becoming mute over the death of his and Vinnie's father (actually, he's faking it because he enjoys the tons of extra attention he gets, which should be obvious to everyone but them). As a result, Vinnie's mother and grandmother don't just neglect her in favor of pampering Mason like a little prince, but seem to expect her to put up with all the problems in her life (her father is gone, she's moving schools and has no friends.) without a word of complaint, and are quick to scold or punish her whenever she acts out. Their incompetence is a major source of frustration for both Vinnie and the reader.
The Girl Next Door: Ruth Chandler is a woman who has taken her nieces Meg and Susan in after their parents died. Believing that all women are whores until proven otherwise, Rith starts starving and emotionally abusing Meg, escalating to physical when she fights back. Threatening to turn her wrath on Susan if Meg resists, Ruth has her sons lock her in their basement and regularly torture her. As Ruth and her sons convince other neighbourhood kids to join in on the violence, she starts allowing the boys to rape Meg. After a young boy naked David tries to stop Ruth, she has him thrown in the basement so she can kill him later, after which he learns that Ruth has been molesting Susan. David escapes, kills Ruth and alerts the police, but Meg dies of her injuries before paramedics can arrive.
In The Hunger Games, the Careers from District 1, 2 and 4 are Child Soldiers that volunteer to be in the game as they were trained from birth to kill others. Given their cruel mindset and superior skills, the Careers always team up to take down the weaker tributes, then gleefully kill each other once the others are dead.
It: It is an ancient, vile monster hailing from the Macroverse. Arriving at Derry millennia ago, It awakens every 27 years to feed on Derry's children, salting their flesh with fear. Killing Georgie Denbrough as Pennywise the Dancing Clown, It continuously harasses the Losers Club, including taking sadistic delight in relishing Bill's guilt over his brother's death, and views itself as the supreme being. Even when its views are challenged after its first defeat at the hands of the Losers, It devotes the next 27 years calculating revenge to rectify it. When the Losers defeat It for the final time, It spends its last moments as a Dirty Coward desperately bargaining for its life, revealing It to be just a hollow bully who needs fear to keep itself ticking.
Paris of Troy in The Iliad is possibly the Ur-Example. Even though the epic tells the story of the Trojan War mainly from the Greeks' point of view, the Trojans generally don't come off as evil, and Hector and Priam are in some ways portrayed more sympathetically than their Greek counterparts Achilles and Agamemnon. Paris, on the other hand, is nothing more than a useless, philandering, cowardly jerk who refuses to take responsibility for causing the whole conflict to begin with. When he duels Menelaus in one book, everyone, Greek and Trojan, hopes Paris will be killed.
Goddess Ishtar herself resents the fact that Goddess Freya is viewed as far more beautiful and elegant than herself. To spite the latter, she frames her for unleashing a bunch of dangerous monsters in the town and sets up shop in the pleasure district to run it like a mafia. She creates a system of forced prostitution, kidnapping both women (to serve as prostitutes) and men (to serve as "clients" against their will). She also traffics in slavery and has her slaves suffer the same fate. Then, for a cheap power-up, she sacrifices the slaves into a deadly ritual, taking and destroying their souls to boost her forces for total war on Freya. Lastly, she has her slaves beaten half-to-death, and rapes them herself, to remove all ability they might have to refuse whatever she might order of them. The last straw is when she has Bell kidnapped and threatened with rape twice. Vindictive, petty, and cruel, Goddess Ishtar is universally loathed on both sides of the fourth wall.
Phryne Jamil is a giant toad-like woman who has deluded herself into thinking she's the most beautiful woman to ever live, even more than both goddesses of beauty. She enjoys beating her fellow familia members half-to-death whether Ishtar orders her to do it or not, and also does the same to whoever crosses her, especially those men who escape her "affection". Said affection consists of kidnapping men either off the street or in the Orario dungeon, dragging them to a torture chamber in the basement of the Ishtar estate, pumping them full of terror and aphrodisiacs, and then torturing them until she gets bored, leaving them a broken, bloody, and permanently impotent mess. She not only happily chains up Haruhime and tries to kill her in a Human Sacrifice ritual, but slaps her around for the tiniest resistance, real or imagined. A woman so disgusting that even her own familia members would kill her if they could, Phyrne Jamil is loathed by both the fanbase and her many victims.
Charles from Jade Green is a perverted alcoholic who has a thing for teenage girls. The Title Character herself is the one that is actually causing the problems in the book, as she is haunting the house following her demise. It then turns out that Charles was the actual villain, and that Jade Green was trying to protect Judith from him.
Aunt Spiker and Aunt Sponge in James and the Giant Peach are both dreadfully abusive towards the title character and have no redeeming qualities. One of the book's most notable moments of Black Comedy comes when they meet a well-deserved Karmic Death consisting of being flattened by the peach that they tried to make money out of.
John Green's novels, being Teen Dramas, don't have true villains, but that's not to say there aren't loathsome people about:
An Abundance of Katherines has Colin Lyford (aka "Other Colin" as the hero's name is also Colin), probably the closest thing to an outright villain Green has written. He's the big man on campus in Gutshot, Tennessee and current boyfriend of heroine Lindsey Wells, even though he used to bully her in elementary school. He's also been cheating on her with her best female friend, and gets found out when he's caught doing the do with her in the middle of a graveyard.
The King Killer Chronicle has Ambrose Jakis. While the ostensible Big Bads of the series are the Chandrian, they remain an enigmatic, looming threat whose motives and identities are major driving mysteries of the series. Ambrose, on the other hand, is a petty, sexist, bullying, smugjackass who goes to every conceivable length imaginable to make The Hero, Kvothe's, life a living hell. The levels of spiteful deeds he engages in ranges from trying to get Kvothe expelled from school and getting him fired from his job, all the way to poison him, torturing him with malfeasance and ordering a hit on him, all the while hiding behind his wealth and connections to make sure he never gets any permanent comeuppance.
La République des imberbes, by Mohamed Toihiri : Guigoz is the main protagonist of the book. Based on Ali Soilih, Guigoz manipulated a far-left group into giving him complete power in the Comoros after their coup d'état. Guigoz proved to be a dictator through his Zazis commandos, ordering brutal punishments against anyone who criticized him, dissolving all political parties and forbidding witchcraft and "sorcery" while having several "sorcerers" as advisors. Upon their advice, Guigoz sacrificed 7 seven-year old kids. Guigoz also manipulated the Comorian youth into joining his ideas leading them to commit murders, thefts, horrors and rapes, thus becoming Zazis. When his advisors told him that spirits were angry and required three sacrifices, including one person truly close to Guigoz, Guigoz tricked his friend and advisor Lulé Ben Katil into killing two people before having him executed. When a group tried to rebel against Guigoz in Iconi, Guigoz went to the village and hid in his car while an onslaught happened, resulting in the deaths of 11 people at the scene and 100 other people executed under Guigoz's orders.
The mayor's wife is a painfully stuck-up Rich Bitch, who believes that she's above everyone else in their small town. She begins a stupid vendetta against Alva, Madicken's family's housemaid. Her husband is also clearly hen-pecked, and she basically forces him to fly with an airplane, despite that it's clear that he's too scared to do it, which causes him to have a Potty Failure out of fright while up in the air.
Madicken's school headmaster is hated by all the children because he's so mean and gruff. Not to mention that he's politically incorrect by modern standards, with his rigid views on how girls should behave and his tendency to let rich kids get away with more than poor kids. But he passes the Moral Event Horizon by humiliating and caning a poor girl, who had stolen his wallet. And to make the situation even worse, he does all of this right in front of her class-mates. Madicken acknowledges that stealing is wrong, but it's made clear that the punishment was too severe for the crime.
In the Magic: The Gathering Kamigawa trilogy, Choryu. He is selfish, entitled, arrogant, smug, and cowardly. When he finally gets his, most readers will want to do a little happy dance. Then they either stop when they find out just how horrifying his fate really is, or they dance anyway because he really was just that insufferable.
Busqueros from The Manuscript Found In Saragossa. Smug and infuriatingly clingy, his unwanted "help" always brings more bad than good (if it brings any good at all), yet he still claims he is indispensable for the viewpoint characters' plans and schemes, and he will not take "no" for an answer.
Masks of Aygrima: Grute is the only boy in the prison Mara is put into. He acts lecherously towards the girls, nearly raping one of them and taking joy in their discomfort. He later kidnaps Mara, planning on taking her to a slave mine to trade for better treatment. Finally dying while trying to rape Mara, he's a perfect example of the kind of people that have no place even in the Autarch's brainwashed kingdom.
Colin from the Mostly Ghostly book series (which incidentally, is made by the same author of the Goosebumps series) is Max's abusive older brother that has a habit of humiliating and injuring him. He crosses the Moral Event Horizon rather quickly when he threatens to feed Max's pet bird to their aggressive dog.
Hennessey puts on an act of being a gentleman, but in reality, runs a vicious human trafficking network which keeps women, especially the impoverished, as livestock and brood mares, subjecting anyone who would betray him to the cruelest of fates. Hennessey regularly allows his clientele to sexually abuse the women under his control, as well as feed on their blood. Identifying Cat as his attempted murderer, Hennessey has her grandparents killed, then takes her mother hostage to trap her. A shameless sociopath beneath his mask of civility, who enjoys profiting on the misery of others, Hennessey remains a chilling reminder of the evils of slavery.
Governor Ethan Oliver colludes with, and frequents, the human trafficking network, using its services for his own personal gain. Having originally used the brothels to rape women, Oliver arranges for the human trafficking network to make derelict women disappear so that he can claim to have cleaned up his state and bolster his political career, further intending to continue the process if he is elected President. A revolting, sadistic pervert underneath his good reputation, Oliver serves as a chilling reminder that humans are just as capable of evil as vampires.
One Foot in the Grave and At Grave's End: Max Williams, the estranged brother of Don Williams, is a former FBI Agent turned vampire. Already a psychopath before being sired by Ian Flannery, Max is stated to have murdered his and Don's parents. Encountering Justina Crawfield after being sired, Max seduces Justina before psychologically tormenting her, claiming himself to be an unholy demon, then walking out on her and her child, actions which drive Justina to be an abusive parent to their daughter, Catherine "Cat" Crawfield. In the ensuing years, Max slakes his bloodlust as a mercenary under Ian's auspices. Disdainful of his half-breed daughter, Max has the erstwhile occupants of Cat's former childhood home murdered by a bounty hunter in order to lure her into a trap upon learning that she is alive, so he can have her killed, all behind Ian's back. Upon being confronted by Cat, Max taunts the former about the circumstances of her conception. Abandoning Ian in favor of ending his daughter's life, Max ambushes Cat and Justina, shooting and brutally torturing the former, and threatening to sexually assault the latter. Max expresses his intention to dismember Cat in order to prevent her from possibly being resuscitated as a ghoul, only to be neutralized by Crispin "Bones" Russell III before he can carry out his plans. A disgusting sadist, driven by a desire to inflict needless cruelty, Max demonstrates some of the most detestable qualities in humans and vampires alike.
In-Universe Example: In Nineteen Eighty-Four, Emmanuel Goldstein, leader of the Brotherhood, actually has two minutes of each day devoted to members of the Party unleashing their fury on him. It's heavily implied that Goldstein doesn't even physically exist, but was instead fabricated by the highest echelons of the Party with the specific purpose of becoming a Hate Sink for its lower-ranking members (thus allowing them to direct their pent-up frustrations about their terrible living conditions away from the Party itself). O'Brien even admits to having authored part of "The Book", which is essentially Goldstein's manifesto, himself.
'Northanger Abbey'': John Thorpe is James Morland's friend and a boorish Gold Digger who seeks to marry Catherine Morland, mistakenly believing her to be a rich heiress. Desiring to have Catherine all to himself, Thorpe makes repeated attempts to sabotage her attempts to make friends with the Tilney family, making shameless lies to force her to spend time with him. Thorpe also lies to General Tilney about Catherine's wealth to get him to drive up his own prospects. When this backfires with the General pushing Catherine towards his son Henry, Thorpe slanders Catherine to General Tilney by projecting his own situation onto Catherine's family, prompting him to throw Catherine, who is staying with the Tilneys at this point, out of the house in the dead of night. A shameless liar who talks of nothing but carriages and horses and speaks with crude language, John Thorpe is the closest thing to a Big Bad in Jane Austen's novels.
Överenskommelser has three characters, who are just there to be hated. Wilhelm Löwenström is an extreme Domestic Abuser, his son Edvard is a serial abuser sociopath, and as if that wasn't enough, we've also got Carl-Jan Rosenschiöld, a sick and twisted combination of the other two. These three men share a view on women, which is just disgusting even by the standards of the era (the 1880s), so they actually think that a man has the right to mistreat a woman in any way he can think of. And as much as Beatrice, the story's female protagonist, becomes the most obvious victim of their abuse and their schemes, many other people are eventually harmed as well. Even other men in the story are repulsed by them.
Sword Art Online has Nobuyuki Sugou. Let us examine the full extent of his villainy: Steals the minds of 300 players just when they are about to regain their freedom from the death game, SAO. Performs horrible memory manipulation experiments on said minds in order to develop a Mind Control technology, which he plans to sell to a corrupt corporation that will no doubt use it for unfathomable evil. Keeps Kirito's lover Asuna (one of the 300, but thankfully excluded from experiments) prisoner in a cage within the virtual world, where he frequently torments and sexually assaults her. Torments Kirito with the knowledge that he is the one keeping Asuna prisoner, and that he plans to effectively "marry" her in the real world (not legally, of course, but that doesn't matter). When Kirito finally shows up in-game, Sugou abuses his admin powers to torture Kirito with excruciating pain while he molests Asuna, and threatens to alter both of their minds. The eventual gruesome and extremely painful death of his avatar at Kirito's hands is well-deserved and very satisfying.
Endou and her Girl Posse from the Phantom Bullet arc, who bully Shino for money by deliberately triggering her PTSD regarding guns. It's even worse in the light novel version, as it's revealed that Shino, desperate to make friends, befriended them without knowing that they wanted to take advantage of her living by herself to party in her apartment. When she finally got fed up and reported them, they found out about her past and decided to bully her to get revenge.
In The Thrawn Trilogy, Grand Admiral Thrawn is far too magnificent to be hated, and the other villains of the trilogy aren't too far behind. This leaves all the hatred of the readers for Borsk Fey'lya, a corrupt, selfish, Jerkass of a senator who seems to take pleasure in being an Obstructive Bureaucrat.
While a mild example, Mrs. Kemp from the Ramona Quimby series is one of its most unsympathetic characters. Since Ramona has to stay at her house every day after school, she takes advantage of the situation to make Ramona babysit her granddaughter Willa Jean for free, and always blames Ramona when Willa Jean does something bratty, because she's older and "should have stopped her" or "should have known better". While she does this a lot, she has a major Kick the Dog moment in Ramona Forever—when Willa Jean breaks an accordion that was a gift from her Uncle Hobart, not only does Mrs. Kemp blame and punish Ramona, but openly shames and humiliates her in front of Uncle Hobart when he comes back. This stings Ramona so badly that she later cries when recounting the incident to her family at dinner.
In Renegades, Frostbite and Gargoyle seem almost designed to be hated. Frostbite, in particular, is the worst example of a Smug Super, putting herself on a pedestal above anyone with weaker powers and constantly mocking Nova, calling her ability as The Sleepless as no ability at all. Her introduction has her torture Ingrid in an attempt to make her lash out, which would give her the excuse to arrest her - and it's implied that this isn't the first time she did that. Even in-universe, her fellow Renegades hate her.
Most of the antagonists in David Weber's Safehold are at least somewhat honorable and reasonable, and even the Group of Four are mostly trying to make sure that the world doesn't burn while they clutch all the power they can. And then you have Zhaspahr Clyntahn, whose list of vices seems intended to make the audience want to see him lose in every conceivable way. Even one of the characters meeting him thinks that realistic villains shouldn't be so obvious.
In Ragtime, we have Willie Conklin, the racist Jerkass fire chief who trashes Coalhouse Walker's car. His crime of vandalism is small potatoes compared to the serial murder and arson spree Walker gets up to after becoming the novel's Big Bad, and he's completely unconnected to the murder of Walker's wife (done by a mob of unnamed characters, so hard to hate) that spurs his descent into villainy. Nevertheless, the reader is invited to hate Conklin over Walker, as the novel goes into great detail explaining Walker's motivations and how he became the way he is, while Conklin is and apparently always was just an asshole.
Quite a lot of what makes Goosebumps scarier to read as an adult is digging deeper into how horrifically stupid, petty and cruel many of the adults and children are. But Alexander from Deep Trouble, Tara Webster from The Cuckoo Clock of Doom, Mr. Saur from Say Cheese and Die-Again!, Vanessa from Chicken, Chicken, Brandon from Headless Halloween and Micah from Revenge R Us are probably the worst examples.
The Relic has Agent Coffey. Mbwun, the creature behind the murders at the museum, is more a Tragic Monster just trying to survive by this point so you can't really hate it. Coffey is a jerkass agent who wrestles control of the investigation from Special Agent Pendergast and his bull-headedness leads to events at the museum getting even worse.
The Silmarillion and The Children of Húrin: Saeros is a racist Elf in King Thingol's court who resented the presence of Turin as a ward of Thingol. One evening Saeros made insulting remarks about Turin's people, causing Turin to injure Saeros. The next morning, Saeros attempted to murder Turin over the last night's events, provoking Turin into stripping him and accidentally killing him by running him off a cliff. When Thingol heard of what Saeros had done, he pardoned Turin, while it was stated that Saeros would be held in Mandos, the land of the dead, for a long time due to his misdeeds.
The Silmarillion: Ar-Pharazon from the Akallabeth was the nephew of the King of Numenor, Tar-Palantir. When the king died, Ar-Pharazon forced the king's daughter to marry him, considered an act of great evil and usurped the throne of Numenor. When Sauron declared himself King of Men, Ar-Pharazon took it as a challenge to his ego and resolved to make Sauron serve him, which backfired when Sauron charmed his way into Ar-Pharazon's council, persuading Ar-Pharazon to worship Morgoth, instituting a Religion of Evil which practiced Human Sacrifice. Sauron eventually persuaded Ar-Pharazon to take Valinor, the land of the Gods, by force, and Ar-Pharazon's choice to lay claim to Valinor doomed Numenor when Eru separated Valinor from the rest of the world and caused Numenor to be lost beneath the waves. While the rest of Numenor is mourned for its loss of a golden age, Ar-Pharazon is not, and he is condemned to linger in the world until the end of time.
Caelan from Skulduggery Pleasant is a blatant knockoff of Edward Cullen: a morose, brooding vampire who lusts after the female protagonist, Valkyrie Cain, to the point that he sees himself as her guardian angel and wants to control her life. He is hated by pretty much every other character (even the other vampires), his obsession is frequently mocked and he's eventually killed by the very person he was so in love with.
Socks and Ruby, from the manga The Rise of Scourge, are extremely petty and unsympathetic. They start off saying to Scourge (then a kitten named Tiny) that "unwanted kittens get drowned or killed" and they egg Scourge on to venture into the wilderness where he meets a young Tigerpaw. Scourge gets savagely beaten to the point of almost dying until Bluestar stops it. When Scourge returns from the beating, Socks and Ruby scoff at him and they claim he should have died and chide him for entering the wilderness in the first place, when it was their goading that did that. As far as awful siblings in the series go, these two are in a class of their own, and indirectly started Scourge's rise to power and subsequent Jumping Off the Slippery Slope. When they get abandoned by their humans, Scourge has them exiled.
Darkstripe is Graystripe's evil older brother and a bully to non-Clan cats. He starts the series as Tigerstar's top enforcer while taunting Firestar (formerly Rusty) with "Once a kittypet, always a kittypet" despite however many times Firestar proves his loyalty to the Clans. He truly begins to sink low after it's revealed he tried to poison Sorrelkit for seeing him meet ShadowClan's deputy Blackfoot. Then Tigerstar orders him to execute Stormpaw and Featherpaw, both halfClan cats and children of Graystripe, his own brother, and a RiverClan cat named Silverstream. When Stonefur, the current deputy of RiverClan, and also a halfClan cat defends them, he is murdered by Darkstripe and Blackfoot together. During the fight against BloodClan, Darkstripe tries to kill Firestar out of sheer malice, despite the fact he is fighting on the side of Tigerstar's killer saying "Nothing matters, all I want is to see you dead." Showing no remorse for any of his actions, and only fearing death when it happens, he was truly one of the most despicable of Tigerstar's minions.
Wet Desert: Tracking Down a Terrorist on the Colorado River: Howard. Being a lawyer in an engineer and manager setting such as the Bureau of Reclamation, rumor has it that he was installed there by politicians in order to sabotage the Bureau's operation.

Cassie's father in Wintergirls is a cold-hearted, unloving, authoritarian parent who is all but stated to be the cause of her self-esteem issues and emotional instability. He never has a moment where he shows that he cares about her, and is always berating her for not being perfect. When her pet mouse died, he told her to stop crying over it because he was watching a baseball game; when a boy snapped the back of her bra in fifth grade and she beat him up, her father yelled at and punished her instead. The only thing he appears to worry about is making her look perfect so he can have a trophy child to show off to other parents, and he doesn't care about her well-being outside of that. It's telling that throughout the novel, while everyone else's emotional reactions to Cassie's death are shown in detail, including his wife's, he himself is never, not once, seen nor described grieving for his only child. It's not a huge stretch to think that his reaction to her death may not have been "My God, What Have I Done?" but "Oh no, 18 years of emotional and financial investment gone completely to waste."
In The Water Margin, a story known for its Black and Gray Morality, it is impossible to hate on the outlaws, no matter how many Kick the Dog deeds they do, due to their tragic backstories and being more or less Forced into Evil. However, to make sure that the readers will someone to root against, GaoQiu, the corrupt and loathsome prime minister of Emperor Huizong and the main source of opposition towards the outlaws, is created (or at least fictionalized) to be utterly despicable without any hint of sympathy. By butt-kissing Huizong, Gao rose from a street urchin into a position of power matched only by the emperor himself, and in the meantime used bribery, incrimination, and even murder to get whatever he wants, eventually ruining enough lives to create a peasant rebellion. One of his victims was Lin Chong, a perfectly innocent man who he framed simply so his wife could be up for grabs, and when he found out Lin has been exiled, he does whatever he can to have him killed (Lin's wife is forced to commit suicide). After the bandits were acquitted by the emperor, Gao sends them to their deaths fighting the Liao Dynasty and Fang La. Even worse is how he gets away with all his crimes in the end, killing the leaders of the bandits out of petty jealousy then talking his way out of punishment. The other Song government officials also deserve a mention, though to a lesser extent than Gao.
