Upon obtaining a Sephira by torturing Nia for five years then forcing all the pain from those years on her at once, Westcott ups his game in slaughtering civilians—including children; sending entire fleets of his own troops on suicide missions in between maiming and killing them on a whim; and dragging entire cities into bloody conflicts. Westcott proudly proclaims every last one of his crimes as being nothing but a hobby to him, and when beaten after first trying to rewrite reality to one where he reigns supreme over a tortured humanity, Westcott tries to drag everyone, his own Dragon included, down to death with him, spending his final moments in glee at his former "friends" mourning his demise.

He has no interest in reclaiming Heaven (he'd much rather Take Over the World) and he and his undead horde of angels instead devour the souls sent to him. That's without getting into his treatment of his daughter. Having found an attractive corpse, Ulcis reanimated her, raped her, and then impregnated her, keeping her alive so that he might enjoy her suffering. When his daughter's birth resulted in the woman dying again and being released from her agony Ulcis tried to hang the child from one of the city's foundation chains. When the girl chewed through the rope, Ulcis recaptured her, abused her, and had her gangraped by his undead, gloating that there was no point in taking her soul because by the end, there wasn't one left. When he encounters his daughter again (her having since become an amnesiac Serial Killer), he gloatingly informs her of what happened to her, forces her to recall it, than indicates that all of his soldiers remember her and would love to do it again. "They remember you. My little Rebecca. My little carnival freak."

Barker: Lord Dracul, ever a sadistic wolf in the skin of a Romanian noble, took the noblewoman Dolingen von Gratz to become the object of his lust and his torturous "affections". Dracula physically and psychologically tortures Dolingen for years on end for his own amusement, regularly maiming her lovely white skin and transforming her into a vampire when she attempts suicide to escape him. Dracula balks at Dolingen's disloyalty, claims he's offered her nothing but patience and affection, then victim-blames her for all of it and kicks up the torture, trying to force Dolingen to murder innocent people and starving her blood-thirst. When Dolingen refuses to harm a young boy and girl, Dracula rips out the boy's neck and tosses their mother into the cell instead, demanding her life at the threat of the remaining child's. Dracula even captured Dolingen's old lover Deaglan; turned him into a vampire; then dismembered him and scattered his body parts to keep Deaglan's spirit in the eternal torture of undeath, killing and resurrecting an entire village just to have them guard Deaglan's heart. When Dolingen escapes again and takes the name Grace, Dracula massacres all his servants in pique, pursues her to England while killing and torturing everyone in his way, and ends the book nailing Grace to a mausoleum before promising "you'll learn to love me in time".
  • Dracula: Count Dracula himself is the Trope Codifier for the modern vampire. A hideous, blood-sucking monster, Dracula commits a number of crimes over the course of the novel, including keeping Jonathan Harker prisoner and trying to drive him insane; kidnapping a baby to feed to his fellow vampires, before sending wolves to kill the mother when she demands her baby back; driving his own servant, Renfield, to madness; sending a wolf after Lucy Westenra and her mother to gain entry to her house before draining her blood and turning her into a vampire (killing Lucy's mother through sheer fear at the wolf's appearance in the process); and turning Wilhelmina "Mina" Harker into a vampire to uncover his enemies' plans against him. Dracula ultimately plans to move to England so that he can feast on the people of London to his heart's content. Overall, the vampire Count is an undead abomination devoid of humanity and worthy of no sympathy.

    • High Prince Rolestra is a petty, cruel man with a very high level of depravity. After murdering his father at the tender age of eight, he ascends to Princemarch's throne and used his position to play other princes against each other for his own amusement, nearly causing several wars. When his request for a Sunrunner was refused he trapped and addicted one to drugs, then slowly cut off the Sunrunner's supply of drugs when he ceased to be useful. He then attempted to use these drugs to enslave and rape another Sunrunner, Sioned, and when he fails burns his mistress Palila alive and banishes two of his children, one being a newborn. When we next hear about him he has cornered the market on the only medicine to a plague and only supplies it when enough of his rivals have died of it. When he enters a war with his greatest rival left alive, Rohan, he salts a battlefield after losing a battle out of spite.

She then concocts a plan with her father to kidnap, drug, and rape Rohan to make her son heir to the Desert.

When she finally lets them go, she releases them into the desert with only a little water and no food.
    • Mireva, a sorceress from the mountains, is a bitter and power-hungry woman. Prior to the events of the story, she introduced drugs to Palila that kickstarted several of Rolestra's villainous acts. She helps Ianthe's sons escape the fire she dies in and trains them into her tools to try to conquer the world with. While orchestrating these plots, she enslaves a princess with a mirror, forcing her to raise an army to try to invade Princemarch, which would cause the death of hundreds of people, if not more. She kidnaps a princess named Ruala with latent sorcerer powers to use as a power source and tries to blackmail another prince to do the same to him. As part of this plot she also impersonates a princess and rapes Rohan's son Pol, then has one of Ianthe's sons nearly rape the princess disguised as Pol. She also threatened to murder two children due to wanting revenge on a Sunrunner.

Dracman often tells a victim they'll be dead in a set amount of time, then freezes time and sends a golem to stalk them, or hunts them down himself, murdering them and collecting their eyes. Living only for his twisted desires and game, Dracman will relentlessly hound any victim he's chosen until he takes their lives and takes their eyes to preserve as a reminder of his victory.
  • The DragonCrown War Cycle, by Michael A. Stackpole: Chytrine, Empress of the arctic realm of Aurolan, has a heart as cold as the tundra over which she rules. She mercilessly drives her subjects to war with blatantly false propaganda, uncaring if they die so long as they advance her goals in doing so, and the conquered territories her forces occupy are treated so brutally that their populations can be reduced to a tenth of what they were in a matter of years; a century of her rule can turn a once-prosperous nation into a wasteland. Chytrine is utterly without empathy or loyalty; when her adopted daughter Isaura turns against her, she coldly declares that she has no daughter and attempts to kill her, and though she gets a good portion of her power through her worship of the Oromise, she secretly fantasizes about overthrowing and enslaving them as well. Though she herself is half-dragon and is allied with several full-blooded dragons, she plans to betray her kin by re-forging the titular Dragon Crown, giving her the power to dominate most of their race. Her vilest deed may be how she gets her Quirky Miniboss Squad; Chytrine has a fondness for using Fallen Heroes as her lieutenants, tricking them into swearing allegiance to her in moments of weakness and then forcibly remaking them into undead warriors in a process that is supposed to be unspeakably agonizing and twists their personalities to be more in line with her desires, leaving just enough of their original selves to be horrified by what's been done to them. The nations of the south lived in fear of Chytrine for generations, for very good reason.
  • Dragonriders of Pern:
    • Lord Holder Fax managed to gain control of seven Holds through various means, mostly conquest. One Hold, however, he "won" by marrying into the leadership...and then doing his level best to kill his Lady wife via childbirth. He also had zero problems with killing every man, woman, and child even suspected of having Ruathan blood in his bid to gain supremacy over that Hold. It's also heavily implied that he if not outright raped, then stole and coerced every half-pretty female in his jurisdiction that he could get his hands on.
    • Lord Holder Chalkin had a jail area that was more or less like a freezer, with small "cells" cut into rock, all of them cold and damp, into which he threw anyone that pissed him off in the slightest. A servant spilled a container of sugar and got two weeks in one of these cramped, cold cells. People were frequently kept in the cells until they died of the cold and damp, and their bodies were thrown into a lime pit, rather than given whatever passed for a normal burial. He was also heavily "tithing" his peoples' produce, whether it was food or textiles or what have you, to the point of forcing his people to starve and work themselves to death in an effort to please him while he wallowed in an excess of supplies of all kinds.
  • Dragons of Requiem series:
    • Dawn of Dragons trilogy:
      • King Raem Seran sees all Vir Requis as diseased creatures who must be purged from the world by any means necessary. Ashamed of being a Vir Requis himself, Raem has multiple Vir Requis executed in public. After discovering his son, Sena, is a Vir Requis too, he immediately tries to kill him, only stopping because Issari, his daughter, begs him not to. Fed up with the sheer amount of Vir Requis in his kingdom, Raem summons a demon named Angel and has her army seek out and slaughter any Vir Requis they find as they rape many of the women in Eteer. He also allows a witch to extract blood from Issari in exchange for information regarding his exiled daughter, Laira; Raem later hires Zerra Blacksmith to kill Laira and the remaining Vir Requis in the north. Once his initial plans fail, and Raem discovers that Issari is a Vir Requis after she tries to kill him, Raem allows Angel and her demons to feast upon the innocents in Eteer so they'll grow stronger and will assist him in hunting Issari and the other Vir Requis. As they hunt, Raem lets his demons feast upon any villagers they find before confronting the Vir Requis army and killing dozens in the ensuing battle. Raem later contacts the Widejaw tribe and turns them all into sphinxes before ordering them to destroy Requiem and kill any Vir Requis they find. Frustrated over his own "disease," Raem spends his free time executing many innocents in the Abyss, before ordering Angel's demon army to eradicate all life on Earth.
      • The ironically-named Angel is Queen of the Abyss, and a fallen deity. Upon being summoned by Raem, she immediately tries to drag him to the Abyss so she can torture him, only stopping because Raem holds all control over what she does. While Raem only wants Angel to kill all the Vir Requis in Eteer, she begs him to allow her and her demons to rape hundreds of women in the city too, which Raem agrees to. Angel and her demon army Rape, Pillage, and Burn as they please while Angel keeps begging Raem to let her army feed on human flesh as well—an offer Raem later agrees to in order to strengthen her army. As Angel's demons continue to wreak havoc upon the neighboring communities, Angel stays in Eteer to ensure her demons keep raping and impregnating as many women as possible. When Issari and many other Eteerian soldiers capture her, Issari tries to take control over Angel, only for her and the hundreds of pregnant women to give birth to half-demons who proceed to slaughter even more innocents. Angel continues to rape and kill indiscriminately while her army massacres villages and cities around the country. During the final confrontation between Angel and the Vir Requis, she starts mind raping some of the characters by making them believe that their fallen loved ones are being tortured in the Abyss. While Raem was driven out of shame and the need to purge the world of Vir Requis, Angel only cares about causing as much death and destruction as possible to satisfy her lust and hunger.
    • Song of Dragons trilogy: Dies Irae is responsible for nearly driving the Vir Requis into extinction. Shunned by his father for the inability to shift into a dragon, unlike his brother Benedictus, Irae takes out his frustration by raping and possibly impregnating his brother's fiancée, Lacrimosa. Upon finding out that Benedictus will take the throne, he kills his father and declares war on the Vir Requis. As he hunts them, he kidnaps Lacrimosa and Benedictus' daughter, Gloriae, and trains her to hate and kill the Vir Requis as well. When Irae discovers that there are still four Vir Requis left in the world, he sends his armies to hunt them all down, not caring how many innocents are caught in the crossfire. After he's defeated by Benedictus, and Gloriae releases the nightshades, Irae banishes Gloriae from his kingdom. While mad that the nightshades harmed his kingdom, he later takes control of them, allowing them to terrorize the world and suck the souls out of thousands of people. Irae also takes his frustrations out on his own soldiers, going as far as having 300 of his men beheaded because they failed to kill any Vir Requis. Irae faces Benedictus and Lacrimosa a second time, and he succeeds in killing his brother before escaping and creating an army of mimics. Not content with using dead body parts, Irae builds a camp where he kidnaps thousands of individuals and harvests their body parts while they're still alive, and even hacks off Agnus Dei's hand. Irae sends his army to finish off the remaining Vir Requis once and for all, and during the battle, he kills Lacrimosa even after she confesses that she's pregnant. A racist driven by his hatred of the Vir Requis, Dies Irae stands out as being one of the worst villains in the franchise.
    • The Dragon War trilogy: Emperor Frey Cadigus is the vicious, tyrannical ruler of Requiem.

Afterwards, he spent several years recruiting thousands for his army; after they're put through Training from Hell, he sent his forces out to exterminate all the surrounding nations, leading to the deaths of millions. When the Resistance is formed, Frey has all his soldiers hunt down and destroy the organization, going as far as imprisoning or publicly executing anyone allied with them and opposing his empire. Once Frey discovers that Rune Brewer, the sole survivor of the Aeternum family, is still alive, he sends his troops out to hunt him down. When the Resistance retakes Lynport, Frey and his troops fly down to the city and destroy it, killing anyone in their path. Frey also lures Rune out of hiding by killing several hostages, two at a time. Frey keeps Rune alive, but only so he can torture him and convert him to his empire. During the final battle between the Resistance and Frey's troops, Frey subdues his own daughter, Kaelyn, and ties her and Rune to a chair. He then points a gun at both of them and tries to make Valien choose which person he should kill. Although Frey claims that he cares about Requiem, he uses his power to imprison, torture, and kill anyone in his way, even those who pose no threat to him.
    • Requiem for Dragons trilogy: High Priestess Beatrix Deus is the new Requiem ruler and the leader of the Cured Temple. As ruler, Beatrix routinely sought out any Vir Requis who could shift into dragons and exposed them to tillvine in hopes of ridding the Vir Requis race of their transforming power. Anyone who refused to be "cleansed" with the tillvine was either murdered or imprisoned and tortured, resulting in thousands of casualties. After Beatrix hears that Eliana, the stepsister of Cade Baker, has the power to turn into a dragon, she sends her daughter Mercy to expose her to tillvine, only to discover that Cade is a Vir Requis too. When Mercy fails to find Cade, she burns down his village and murders his stepparents. Once Beatrix realizes that there are other Vir Requis who oppose her rule, she tells Mercy to hunt them down by any means necessary, and later imprisons her own son Gemini to be tortured to death after he inadvertently allows two Vir Requis to escape. She later orders Mercy to murder thousands of infants when her supply of tillvine runs low and declares war on the Horde, resulting in the deaths of hundreds of thousands. Due to Mercy's repeated failures, Beatrix summons an army of bonedrakes to sniff out the Vir Requis and finish them off. In the final battle, when she's confronted by her former lover, Korvin, who tries to persuade her to surrender peacefully; Beatrix responds by subduing Korvin and orders her guards to hang him from her Temple's balcony. While Beatrix acts like she cares about the Vir Requis, she's really a hypocritical, abusive mother obsessed with "curing" the Vir Requis of their "disease," even if it means taking innocent lives.

Infecting the minds of numerous wizards, including nearly all the younger wardens, with his magical ink, Peabody subtly brainwashed several into becoming his "suicide bombers". Throughout the Red Court war, Peabody sabotaged the White Council, confusing the Senior Councillors minds and passing their secrets to the Reds, causing them to lose numerous devastating battles; Peabody also personally sabotaged Archangel's defenses, allowing the vampires to wipe out the entire city. Peabody likewise gave the vampires the information that allowed them to carry out a devastating nerve gas attack on the wounded, also killing thousands of innocent civilians as collateral. Summoning a Shoggoth for the Black Council to exploit, Peabody forcibly bound it to Catherine Taylor, risking unleashing "an era of horror and carnage as yet unknown to man". Attempting to start a civil war within the White Council, leaving them too weak to continue to stand against the Reds, Peabody brainwashed Captain Luccio into murdering Senior Councillor Aleron LaFortier, planning to ensure her and Donald Morgan's executions, escalating tensions with Aleron's numerous supporters and triggering potential mutinies within the Wardens.

Playing the part of a blood-addicted junkie, the Red King manipulates his courtiers, pitting them against his enemies and one another, and shows no compunction in sending his own daughter to her death when she opposes him. The misery of the Red King's actions makes South America into a living hell for civilians and those who dare to oppose the vampires, and is so horrible a formerly loyal servant is driven to Knight Templar levels to destroy the Red Court at any cost. One of the most ancient, powerful and evil vampires in existence, the Red King is finally brought down by a sacrificial spell he intended for Harry Dresden's entire family line—one he was going to initiate by sacrificing Harry's 8-year-old daughter personally on the altar.

  • The Drowned Cities: Lieutenant Sayle is Colonel Glenn Stern's right-hand man, and acts as The Heavy for most of the book. The oldest soldier in Stern's service, Sayle acts as a recruiter, press-ganging children into becoming soldier boys for the United Patriotic Front, burning their rank into their faces with acid, and convincing them that the outside world has nothing to offer them. A particularly cold-blooded sadist, Sayle started the UPF's practice of mutilating prisoners by cutting off their hands and feet and leaving them for their comrades to find, and put out of their misery. The practice eventually spread to other child armies, like Taylor's Wolves and the Army of God—which Sayle intended because it means that his own boys will be less likely to surrender. Sayle treats civilians with an even more deliberate brutality, endorsing, encouraging, and participating in his boys' practice of Rape, Pillage, and Burn; he's particularly vicious towards women, informing the heroine, Mahlia, (while neck lifting her) that "maybe I'll just stand here and watch you kick. I like it when a pretty girl kicks." During the climax, Sayle even manages to violate the soldier boys' tenuous moral code, when he has one of his own boys, Mahlia's former friend Mouse, mutilated in order to try and break Mahlia, a fact that shocks and disgusts his Number Two, Sergeant Ocho. What makes Sayle especially bad is that he doesn't buy into Colonel Stern's Well-Intentioned Extremist rhetoric, nor is he a drugged-up PTSDing child, like most of his boys. Ocho notes that Sayle is Straight Edge Evil because "what got him high wasn't any booze or drug or girl. It was the hurting. Sayle liked people hurt."
