"A Little Piece of Heaven" by Avenged Sevenfold: A guy's girlfriend rejects him, so he stabs her 50 times, rips out her heart while she's alive and eats it, and he rapes her corpse. Karma seems catches up to him when his zombie girlfriend kills him, but she forgives him in hell and the two of them procede to butcher then guest of a weddings.
"Such Horrible Things" by Creature Feature: The main character talks of all the things he's done while stating outright that he should be killed gruesomely for having done it all. The way he muses about one incident with sinister chuckle says he enjoyed every moment. The scariest part is what he did when he was 14. At first, he says that nothing happened, but then he remembers "that one time" and chuckles. Cue a series of screams and about 50 seconds without any narration.
"The Rake's Song" by The Decemberists: The eponymous character relates how he murders his three children after their mother died in childbirth because he wants a new life, including beating his son to death and burning the body for daring to fight back, and concludes by saying that he doesn't regret it at all.
"The Curse of Milhaven" by Nick Cave: Lottie, the 14-year-old title character and narrator is such a sadistic, prolific, and senseless killer that her actions are mistaken for some sort of curse upon her hometown. First, she murders a young boy by bashing in his head, and hides his body in a creek. She then decapitates a handyman and leaves his head in a fountain, and stabs her neighbor to death. After getting caught, she happily describes the rest of her crimes in detail: on top of the murders, she had taken down warning signs around a lake in late Winter, resulting in the deaths of 20 children, and committed arson around a slum, burning it and its inhabitants to the ground. She ends the song by explicitly stating that she feels no remorse, and makes it clear that she only committed these crimes for fun.
The Emerald Sword Saga by Rhapsody of Fire: Akron, the Big Bad from the Concept Album series is a ruthless warlord and champion of the Dark God Kron. Akron begins by destroying the city of Ancelot and capturing its princess Airin. He lures The Warrior of Ice into giving him the famed Emerald Sword by threatening to execute all his prisoners, but has already killed them all. Akron has princess Airin raped to death by his demons in front of the men who love her, before having her beloved Arwald tortured and executed by being thrown into an acid pool. Akron's armies run rampant, destroying everything they encounter and slaughtering all they can. After a long campaign, when the Warrior of Ice is captured, Akron has him tortured and then decides to execute him by having him fed to the ravenous water snakes in the swamps. Akron is so horrible, even his Noble Top Enforcer Dargor finally turns on him to help destroy him after witnesses his horrible excesses.
"Excitable Boy" by Warren Zevon: The title boy is obviously insane from the start of the song, but as it goes on his actions become more psychotic until he rapes and kills his date to the Junior Prom. Then, after getting released from an asylum after 10 years, he digs up her grave and makes a cage out of her bones.
"Angels" by Within Temptation: The unnamed priest lures the main character into his house after her companion seemingly abandons her on the side of the road. Bait the Dog ensues as he is established as a nice guy. The woman goes to his back room and discovers newspaper clippings of a bunch of other women. It is then revealed that he is not a priest, but rather a Serial Killer who dresses up as trustworthy people (such as a doctor, a clown, and a priest) and lures women into his home to kill them. The killer then chloroforms the woman and takes her out into the desert to kill her by burying her alive next to the at least 16 graves of the other women he killed. Just when it looks like it's the end for her, she, her companion, and several other band members reveal themselves as angels (hence the title) and the souls of the women he killed come back to kill him. He is never given any reason for why he likes to bury women alive, leaving us to assume that he does it For the Evulz. Throughout the video, his eyes are shown to glow an unnatural red.
"Garbage" by Tyler, the Creator: The Serial Killer is initially just an ordinary drug dealer who later found joy after killing a guy for trespassing his territory. Addicted to killing, he then goes on to commit numerous murders and slaughters a task force that tried to arrest him. He also keeps a number of victims alive in his house basement, rips out their arms and legs so that they wouldn't leave, and tortures them for his own amusement. It is also implied that he killed children or at least drugged them to the point where they are beyond saving.
Greco-Roman myth is replete with examples of mortals who tried to outsmart the gods and paid for it. Yet none of them found as disgusting a method, or deserved their resultant punishment, as these people did:
Tantalus, a Greek king who was a favourite guest and host of Zeus', proved that familiarity breeds contempt. Deciding that the gods were fools rather then omniscient beings, Tantalus set out to show that they could not even tell what they were being served for dinner, let alone comprehend the secrets of the cosmos. Murdering his own son, Pelops, Tantalus had him boiled, and served to the gods as the main course at dinner. By tricking the Olympians into eating their host's child, he sought to demonstrate that the gods were utter imbeciles. Instead, he proved that he was a relentlessly vile person and that even Olympian godshave standards. When his ploy was uncovered, Zeus both resurrected Pelops and trapped Tantalus in an Ironic Hell, cementing cannibalism, the slaying of one's own children, and the mistreatment of guestsnote see xenia, the Ancient Greek code on how to treat guests as major taboos in Greek culture.
Following in Tantalus' bad, bad example is Lycaon, tyrant of Arcadia, and the first werewolf. Appearing in several compendiums of myth from the time period, the most infamous version of Lycaon's story appears in Ovid's Metamorphoses. A cruel, bloodthirsty ruler, Lycaon was angered when his citizens celebrated Jove's (Zeus) visit to his city. Determined to prove that Jove was not really a god, and was therefore unworthy of their worship, Lycaon offered Jove a room for the night, plotting to murder him in his sleep. He also, like Tantalus before him, sought to test Jove's divinity, by serving the god human flesh at dinner. Butchering a hostagenote in some earlier versions of the story, it is his own son or infant grandson, Lycaon roasted his flesh, ate some of it himself, and placed it on the table before Jove, who reacted in outrage and disgust, cursing him with lycanthropy. Watching the newly lupine tyrant slaughter a herd of sheep, Jove noted that Lycaon's nature had not changed; it was simply that he was now as savage on the outside as he had always been on the inside.
Egyptian Mythology: Apep, more widely known in the West by his Greek name, Apophis, the Egyptian God of Evil, who was associated with darkness, chaos, and destruction. Residing in the Underworld, Apophis took the form of a colossal snake, and every night, would attempt to devour the sun god Ra, as he made his way through the land of the dead, hoping to leave the world without light or life. During the day, while Ra was in the sky, Apophis would feed on those dead souls who were not properly protected against him, leading to their complete obliteration. His motives for doing so were that, as a primordial being associated with the dark, he hated the fact that there was a sun, or life on earth, and aimed to go back to the way things used to be. He was also the leader of armies of demons, and sought to subvert mortal confederates into aiding his nihilistic agenda. Reviled by all the other deities, including Set (who eventually took on the role of God of Evil), and universally loathed in Egypt, Apophis was the only god to have the distinction of never being prayed to. Instead, temples and ceremonies were set up to pray against him.
Book of Esther of the Judeo-Christian Myth: Haman who was a treacherous advisor offended by one Jew's refusal to bow to him, using this as justification for plotting the genocide of the Jewish people. Various Judaic traditions elaborate on this, noting Haman had a picture of an idol embroidered onto his robes so that he could force Jews bowing to him to violate the taboo against kneeling to idols. The very trees from which he hoped to build his gallows recoiled from his unclean presence, and unlike some Biblical antagonists, he's not an agent of divine retribution, just a self-important bastard who can't accept being disrespected. Even Haman's wife tells to his face that he has gone over the line, and that his obsession with killing the Jews would soon become self-destructive; he ignores her and goes ahead with his plans. His name has become a watchword for anti-Semitism and he is viewed in rabbinical tradition as an archetypal evil figure.
Zoroastrian Myth: Angra Mainyu, alias Ahriman, is the Evil Twin of creator god Ahura Mazda, and the antithesis of everything good and just. Declaring that "it is not that I cannot make anything good, but that I will not," Angra Mainyu sought to prevent Ahura Mazda from creating life in the first place, by slaying the primal bull (his first creation). He seduced the daevas (demons) away from Ahura Mazda, transforming them into spiteful beings living only to spread fear and hatred. When Ahura Mazda created sixteen lands, Angra Mainyu responded with sixteen scourges, including old age, disease, war, vice, and death. He created the monster Aži Dahāka, destined to slay one-third of the earth's population, and turned him loose in the world. He made two separate attempts at destroying the Earth's water supply and leaving all creation to die of dehydration. He made Jeh, the primal whore, so that women would suffer from menstruation, birth pangs, and mistrust from men. He tried to coerce Zoroaster into coming over to his side, and then set the daevas upon him when he would not. Responsible for the very existence of evil, Angra Mainyu works to seduce men and women away from Ahura Mazda, so they might join his campaign for control of reality. Hating everything good and just, and angry that he is not the one who created everything, Angra Mainyu's ultimate goal is the annihilation of the universe.
Ox Baker may well have originated the notion of the "monster"Heel (think Brock Lesnar) during his career, which stretched from the sixties into the eighties. Billed as a Psycho for Hire and Hero Killer, with the Catch Phrase "Hurting people is fun," Ox more than lived up to his reputation as an unfeeling brute. During a tag team match, Ox used his Heart Punch to fatally injure Alberto Torres, who died three days later of a ruptured appendix. Whether this was intentional or not, Ox firmly established his monster credentials not only by being completely unapologetic—and in fact, constantly boasting about killing Torres—but by continuing to use the Heart Punch (now known as the Hurt Punch) as his Finishing Move, this time with intent to kill. This resulted in another death, this time of Ray Gunkel, who died in the ring of a heart attack after receiving Ox's Heart Punch. While his performer Douglas A. Bakernote who was incredibly torn up about the deaths, and was cleared of all wrong-doing would go on to portray faces, the Ox Baker persona never experienced a Heel-Face Turn, and would spend the rest of his career boasting about how any match against him just might be somebody's last.
Dino Attack RPG: Nearly every villain has some redeemable trait... and then there's these guys.
The Brickspider Bot v1.0. Simply put, the Brickspider Bot is a cold-blooded killer, with quite a body count during the battle for LEGO Island. The Brickspider Bot also assisted Dr. Rex in leading the Dino Attack Team to the trap in Quadrant 14, which took even more lives. It was also noted that the Brickspider Bot is a grave robber who picks apart dead bodies to find ways to improve itself. It was created to be a mere mook, but Evil Ogel and General Evil realized that it was too intelligent and too evil, and so they knew it had to be destroyed. Even Cyber-Bully was disgusted by the Brickspider Bot's presence. The Brickspider Bot feels sadistic pleasure in torturing and terrorizing its victims before killing them in cold blood. The sole reason the Brickspider Bot wants to see the apocalypse happen is because it revels in the death and destruction it will cause, i.e. In Love with Your Carnage. Never portrayed sympathetically, and ultimately killed by the heroes.
Michelle Glados is willing to kill a world's population in a horrible apocalypse that she helped to bring about... you know, For Science! The fact that she suggests this so emotionlessly only makes it worse; although she rarely shows emotion, she feels no regrets over what she has done, and her emotionless exterior actually masks a sadism rivaling that of Loop and the Brickspider Bot. Otherwise, one might argue that her lack of caring only makes her an even greater monster. She knowingly took a group of Dino Attack agents, disguised as her own mooks, and sent them to the front lines of the battlefield where they were shot and killed by their own teammates. Then, she activated poisonous gases to treat the survivors with a slow, agonizing death. But the greatest Player Punch of all was when she killed Amanda Claw and Trouble, two beloved long-runners of the Dino Attack RPG, which numerous players attested to having radically altered their perception of the RPG as a result. Her presence usually elicits complete disgust from those around her. Even if she does have a Freudian Excuse in the form of a Friendless Background, that's no excuse for her behavior today, as called out by Frank Einstein. When Glados and her fellow scientists realized that they were being manipulated by the Darkitect all along, they were all given a chance of redemption. Most of the other scientists took that chance and, by the end of the final battle, were fighting alongside the heroes. Glados did not. In fact, she barely even acknowledged the possibility that she could have redeemed herself, instead choosing to continue pursuing her own goals up until her death.
Baron Typhonus, the Darkitect, is considered to be on nearly-Eldritch levels of unspeakable horrors. He wants to destroy the planet... and then, from there, the rest of the universe. Being the RPG's only Omnicidal Maniac, he is frequently a target of Even Evil Has Standards and Evil Versus Oblivion. He actively plays with the minds of numerous characters, toying with their emotions to increase their suffering or bend them to his will. He has even brought peoples' worst fears to life in some of the cruelest ways possible. One of the worst things he has done on-screen is his Divine Intervention, saving Dr. Rex from death, but in doing so, leaving him in a state of endless pain and agony while reducing him to little more than a puppet that he could control, forcing him to keep fighting a battle he no longer wanted to fight. That's right. He turned Dr. Rex, who was a monster in his own right, into a woobie. He has no regret or remorse for anything he does. When his minions, nothing more than tools to accomplish his goals to him, outlive their usefulness, he offs them without a single second thought. In fact, throughout everything he does, he remains arrogant and smug about it, enjoying seeing the pain he inflicts upon others. While he cannot be killed, his presence is indefinitely banished from Earth, which was the only way the RPG could have a remote chance at a happy ending.
Global Guardians PBEM Universe: The worst by far is The Blood Red King (the Anthropomorphic Personification of Terror), who, on a lark, once invaded the maternity ward of a Belgian hospital and suffocated all the babies whose name began with an "odd-numbered" letter (A = 1, C = 3, and so on). He once forced a crusading televangelist to rape, strangle, and dismember his own teenage daughter during a live television broadcast because he didn't like the man's hair.
William Shakespeare has produced timeless works with quite the incredible and diverse output. From some of his plays have come villains who are impressive in their depravity centuries later.
Othello: Honest Iago is one of the most famous examples of this trope in English Literature. A bitter Venetian officer who resents the promotion of another man over him by his commander, the Moor Othello, Iago schemes for revenge by ingratiating himself with Othello and driving him to madness with insinuations his beloved wife Desdemona is having an affair with the officer Cassio. Iago undermines Othello while acting as his friend. Iago murders his accomplice and his own wife to cover for himself, and at the end, convinces Othello to murder Desdemona. At the end, Iago displays no remorse and refuses to speak one word more in his whole life. Through the play, Iago goes through various motives for his evil: racism, envy suspicion Othello is sleeping with his own wife...but at the end he simply concludes there is no motive. He simply enjoys this.
Richard III is one of the most famous examples of a Historical Villain Upgrade in English drama. Richard informs us early on that he is determined to prove a villain and ruin the day for everyone else. To that end, he seduces Anne Neville, whose noble husband he himself murdered, with every intent of discarding her later. He has his brother George, Duke of Clarence, sent to the Tower of London and murdered, drives his older brother King Edward IV into an early grave and has Edward's two young sons imprisoned in the Tower of London, before having them murdered. He poisons Anne herself, and begins having his allies killed. On the night before his battle with Henry Tudor, he is visited by the spirits of his victims, who tell him to despair and die. Richard is left alone, deserted by all, and at the end, he admits that even he has nothing but hatred for himself.
The Lion King musical: Scar commits the same crimes that his movie counterpart did and goes beyond that. During the musical, Scar became more and more paranoid as time went by and he also felt that he was being tormented by his older brother even in death. Unwilling to admit that he was terrible at governing the Pride Lands, he instead condemns all his subjects to death so that he wouldn't have to accept that maybe he wasn't as good at being a king that he thought he would be. He also attempted to force himself onto Nala (a scene cut from the film), which becomes even more disturbing in hindsight considering that he tried to have her killed along with his nephew when they were children. The musical version of Scar is nothing more than an egotistical, treacherous, and murderous feline.
Der Vampyr: In Heinrich Marschner's opera, an adaptation of John Polidori's short story "The Vampyre," Ruthven is a Satan worshipper, who must drink the blood of three women over a twenty-four hour period or forfeit his soul to Hell. He kills a girl named Janthe, then fakes his death after her father shoots him, making his friend Aubrey, who he once saved, keep his being a vampire a secret. The next day, Aubrey finds Ruthven has hypnotized his Love Interest Malwina's father into engaging them; he has also begun preying on a girl named Emmy. Ruthven kills Emmy, handing her soul over to his masters, then goes through with his plans to marry Malwina, while using his supposed friendship with Aubrey and the oath that the latter swore, to keep him from warning her and her father that Ruthven will kill her. In the end Ruthven is struck down by his own masters, moments before he can kill not only Malwina, but Aubrey too, whom he regards as a traitor for trying to stop Ruthven from killing his girlfriend.
Eclipse: Freiherr Eighinn Stossuhl is a brutish, Trigger Happy thug who firmly believes that Might Makes Right. In his first appearance, he threatens to attack a neutrally-aligned country (Cessair) if they failed to turn in the main character. When the main character actually leaves peacefully, Stossuhl attacks Cessair anyway, in a war that cost the lives of 86,492 people and eradicated Cessair's entire infrastructure. When he gets hit by a sniper, Stossuhl responds by destroying an entire building; he admitted that the sniper probably wasn't there anyway. He incinerates an entire platoon of his own soldiers when they took too much time to get through a maze. When an injured soldier grabbed his ankle, Stossuhl destroyed his entire upper torso because he was stopped from sprinting. When another soldier offers to patch him up after a fight, Stossuhl pushed his skull into his torso because "Real men never disarm themselves." When an informant reveals that all of his targets had escaped, Stossuhl immediately chokes the informant to death, while still demanding to know where they went. He proceeds to order the eradication of Cessair, and when his colleagues called him out on it, Stossuhl continues the shelling out of spite. At a public speech, Stossuhl attempted to divert his culpability in the invasion by claiming his colleagues supported it (when they didn't). Finally, Stossuhl publicly executed close to a hundred Cessair prisoners (and his own bodyguards) by unleashing a stream of magma that morphed them into a mesh of dry, organic rock.
Atop the Fourth Wall: Mechakara is a robot from an alternate dimension where Linkara's Robot Buddy Pollo turned evil, killed him, and robots overthrew humanity. His plans solely revolve around sending our protagonist into a mental breakdown; and, when that fails, he captures him and plans to kill him slowly, simply because his death went too fast the first time around. While that would normally make him just another killer robot, what shoots him over the top is how, after getting the magic MacGuffin that he came for, he decides instead to destroy all organic life in the multiverse. He's a cold heartless monster and the fact that he's returned is a signal he'll only get worse from here. It gets particularly bad in the Silent Hill Dead/Alive videos, where Mechakara slowly Mind Rapes Linkara into thinking he's the (actually long dead) man who tortured his daughter to create Linkara's Magic Gun.
Suburban Knights: Malachite wanted to destroy all of the world's current technology and killed anyone who disagrees with him and/or gets in his way. He cannot even pass off as a Well-Intentioned Extremist, as towards the end of the series, he picked up his cell phone, and it had been demonstrated that he didn't think that science is bad, but that he only hated it because he was defeated by its champion, so he swore a violent revenge as a result.
Deathlist is a psychopathic, Nigh Invulnerable cyborg who gets off on widespread carnage and considers the world to owe him a debt of pain. The most horrific thing he's done so far was to kidnap a mutant superheroine, jam a power-neutralizing device into her skull, then hack off her arms and legs and give her to his troops as a sex toy. Then, when she died after more than a month of torture and rape, he impaled her corpse on a pole with a thank-you message to one of her former teammates carved into her chest. Not even his Freudian Excuse (namely, that his parents tried to kill him by crushing him in a garbage compactor) nets him any sympathy after that.
Hekate is a wizardess supervillain-in-training whose rap sheet includes using a spell to enslave two of her classmates for a year, during which they were repeatedly raped and otherwise abused while being completely aware of what was happening but powerless to stop it, as well as the fact that the athamé she used in the spell was empowered by the ritual sacrifice of two young children. Not only that, but during a magical battle with Fey (after trying and failing to ensnare her in the same enslavement spell mentioned earlier), she summons a trio of iron elementals using the promise of dozens of future sacrifices. To top all that off, she used her athamé to stab Jade in the heart beforehand, just to torment Fey.
The SCP Foundation specializes in securing and containing the worst abominations and monstrosities known and unknown to man in order to protect the world and its population. Several of the inmates of their facilities have been especially monstrous.
SCP 953 is a Korean Kumiho who makes a habit of devouring human livers. Before she was captured, the Kumiho would go on violent sprees to rip the livers from their owners and proved herself to be far more than just a predator. The Kumiho would proceed to draw out her victim's agony and viciously torture them to death, relishing in their pain. When she escapes, the Kumiho will inevitably begin her murders anew, including an attack on a furry convention that left many dead. She also murdered an agent and performed sexually indecent acts on the corpse. Her worst crime, however, was telepathically forcing a mother to murder and cook her own child.
SCP 993, AKA Bobble The Clown functions as The Corrupter to children. Using the power of television, Bobble would out viewers above the age of 10 into a trance while the children were shown graphic acts of Bobble committing murder and other evil acts. Many of the children would grow up to become serial killers themselves. Bobble himself describes himself reaching into the heads of children and happily twisting them. By his own admission, Bobble has been creating monsters for 'quite some time' and has even given his child victims instruction on how to release monsters from the SCP foundation that could cause the end of humanity. When interviewed by a foundation doctor, Bobble revealed he has been creating monsters for 'quite some time,' and that he has been tormenting humanity since the caveman days.
SCP 1790 is a being that can respawn whenever it dies by possessing a human infant. Seemingly human, it uses each lifespan to found a powerful cult and eventually institutes ritualized mass murder and human sacrifice. When it is not stopped, SCP 1790 will direct its followers on large-scale mass murder campaigns against the general population before abandoning the cult and moving on to start a new one.
