After settling in Krynn, Malystryx hunted down and murdered other dragons, taking their skulls and inciting a dragon purge. Using the skulls as a sinister totem, she mutated the land around her into a hellish wasteland and allied with barbarians and ogres to destroy and enslave any innocents left.

In the Haunt ''Battle of the Bhaalspawn'', Bhaal calls for his children to gather in Baldur's Gate before influencing their minds to convince them to all [[InvoluntaryBattleToTheDeath fight to the death]], [[AbusiveParents cackling with delight as he watches]]. Responsible for more Haunts than any other villain in the game, Bhaal treats Baldur's Gate as little more than a playground to cause death and destruction.

* [[NamesToRunAwayFrom Bargle the Infamous]], the Baron's former [[TheDragon right hand man]], is just as evil. As the Black Eagle Barony's number two, Bargle enforced its brutal reign of terror, and deserted it when it fell. Bargle had used many innocents and captives in twisted experiments. He later participated in destroying the flying city of the gnomes and captured a well-known cleric to father his child on her, after presenting her with the tortured corpse of her husband.

Seeking to punish life itself for his death, Orcus wiped out a world with a plague and kept the souls in tortured anguish, intending on massacring the City of Sigil and converting its inhabitants into an undead army to steadily [[OmnicidalManiac exterminate all life in the multiverse]]. Returning to his demonic status, Orcus continuously seeks his lost godhood, even rerouting souls from his nemesis the Raven Queen to him so he may twist them into his own slaves.

* ''Crystal Spheres'': [[OurVampiresAreDifferent T'laan]] is an ancient vampire that felt so much hatred and rage during his final moments that Death itself made a pact to turn him into an undead monstrosity to spread terror across the cosmos. Unique among vampires, T'laan kept his sanity by indulging his fascination with mortal life. He would [[PlayingWithSyringes experiment]] on and [[TheyWouldCutYouUp vivisect]] his victims while [[AndIMustScream they were still alive]], and would abduct women to rape them only to murder them when his undead state kept him from feeling lust.

T'laan [[OffingTheOffspring devoured all his children]] and moved on to a new solar system called Greatspace where he learned from his mistakes. He [[ManipulativeBastard charmed his way]] into the ruling family, murdered the beloved king, and blamed his death on the king's son and sent assassins after him to ensure his death as well. T'laan created a powerful artifact that blackened out Greatspace's sun to end all life there as well, but ensured his survival by kidnapping countless innocents to use as cattle back in his lair in Darkspace.

The Fool [[WasOnceAMan was once a human captain]] named Romar who used the nearly godlike power of the Spelljammer to rampage across the sphere and take revenge on anyone who he ever deemed to have crossed him. When the ship itself tried to cast him down from captaincy, this evil captain called on pacts with demonic powers to turn him into an undead abomination. The Fool kills anyone who explores the warrens inside the ship and [[{{Necromancer}} raises them]] into his army. Seeking to destroy all life on the Spelljammer, the Fool secretly [[ManipulativeBastard manipulates]] a group of [[FantasticRacism human supremacists]] into spreading chaos and mayhem upon the nonhuman population. In particular, he used them to murder dozens by bombing the elven academy and placing blame on the goblinoids, igniting fierce war between both factions. He allied with the vicious Neogi and gave them a magical plague they used to wipe out the Beholders, and hired an assassin to murder the heads of many of the factions and spread turmoil. When the next captain arrived and the gardens on the ship closed, the Fool intended to lead his undead horde to slaughter the starving population before murdering the Spelljammer itself an raising it as his own undead creation. With the Spelljammer under his control, the Fool intended to ravage the cosmos and [[OmnicidalManiac wipe away all sapient life]], one crystal sphere at a time.

An inspection of his lair reveals twisted abominations he has created, [[AndIMustScream living in endless agony]], and a host of Dryads he has kept enslaved as his concubines. Irenicus forces the hero to awaken his power as a child of the dead god Bhaal so Irenicus can steal his soul, powering his magic with the souls of luckless captives who he states have no purpose but to die by his hand.

Having begun life as a mortal warlord who led his armies to multitudes of atrocities before being slain by the Eladrin Paragon Gwynharyf after [[BadBoss annihilating his own followers]], Kostchtchie's angry soul rose to power in the abyss to become so vile that [[EvenEvilHasStandards even other demon lords loathe him for his evil]]. Advocating genocide and mass murder, even seeking to exterminate any frost giant who fails to worship him, Kostchtchie even kidnapped a Valkyrie named Geirskögul, [[RapeIsASpecialKindOfEvil raping her]] to beget a half-fiend daughter whom [[AbusiveParents he tortured]] to open a gateway to the realm of Ysgard, leaving Geirskögul broken and insane.

* ''Something Wild'' module: [[EgomaniacHunter Garond the Claw]] is a [[PsychoSupporter devout servant]] of Malar, the evil god of the hunt, and masterminded a horrible scheme to greatly spread the power of his god. Normally content to hunt living beings in his god's domain, Garond one day found a secret portal to the Beastlands, one of the heavenly planes. Garond concocted a twofold plan when he found this untamed plane full of animal life. In the beginning, he used magical bowls to capture the souls of the spirits inhibiting the Beastlands. The spirits, taking the forms of sentient animals, were either hunted for sport by Malar's followers or fed to the evil god itself. Either way, the spirits were utterly destroyed when killed outside of the Beastlands. Eventually, Garond sought to move Malar's entire realm to the Beastlands permanently. Discovering a powerful mage called The One communing with the Beastlands itself, he kidnapped a dream hunter and forced her to give The One horrible nightmares of being hunted down and torn to shreds again and again.

* [[WickedWitch Mormo]] is the titan of poison, snakes, and evil witches and hags. In perhaps her most significant act, when Gormoth--another titan who was technically her brother--created the viren--the first sentient race to be created by the Titans--she felt jealous of his creation and poisoned him with a species of parasitic worms so she could steal his creation, said worm infestation leaving Gormoth [[AndIMustScream completely helpless and in agony for centuries as he writhed beneath the ground]]. Even when he finally recovered he was both permanently disfigured and DrivenToMadness, and thus went around trying to warp countless other creatures into monsters. Additionally, Mormo was responsible for creating numerous AlwaysChaoticEvil races, including most species of hag; and frequently required HumanSacrifice, usually by throwing people into pits full of snakes or poisoning them to death. She was also extremely petty and cruel even to her own loyal followers. In one case, when a powerful hag spellcaster invented a spell to create an entirely new race of creatures, a jealous Mormo cursed the hag by turning her into a [[MookMaker Darkwomb]]. Mormo even [[AbusiveParents tortured her own child Chardun]] endlessly until he became the GodOfEvil she desired.

Interpreting "Death" as "Murder", Bhaal's [[ReligionOfEvil dogma]] dictated that his followers make it a habit of killing innocent people on a regular basis as sacrifices to Bhaal. Receiving a vision of his own death in the Time of Troubles, Bhaal sired countless mortal children with the specific purpose of serving as his eventual SoulJar. [[ArchnemesisDad Despising all of them simply for existing]], Bhaal left a curse to condemn them all to pain and suffering while arranging for them all to be murdered in hopes of bringing him back to life and punishing them for their very existence.

* [[JerkassGods Myrkul]], Lord of Bones, was the old god of death before Kelemvor. While Kelemvor has a firm set of morals and only tolerates the Wall of the Faithless because it's necessary for [[GodsNeedPrayerBadly the continued existence of the other gods]], Myrkul was an utter sadist who, besides creating the Wall, took gleeful joy in witnessing the [[AndIMustScream agony and suffering]] the Wall caused. He is stated to have ruled his faith with an iron fist, purposefully leading his followers through sheer fear of his retribution, and executing anyone who defied him, be they man, woman or child, in sadistically brutal fashions, such as [[ManOnFire burning them alive]] in a giant furnace. His greatest atrocity, however, was [[NeverwinterNights2/MaskOfTheBetrayer what he did to one of his best priests]], who had had enough of the injustice of the Wall and attempted to destroy it. Initially, he just left the priest to rot on the Wall, but just before the priest fully merged with the Wall and attained some measure of peace, Myrkul decides that he hasn't suffered enough and transforms the priest into a mindless being of pure, unbridled hunger that feeds on souls, then sets it loose upon the world, knowing full well the chaos it will surely cause.

Even before finding the Crystal Shard, Kessell murdered his mentor, whom he considered like a father, on the order of a cabal of {{evil sorcerer}}s in the hopes of gaining power and prestige. Ultimately nothing more than a loose end to tie up, Kessell was abandoned in the wastelands of Icewind Dale where he found Crenshinibon and set out to use its power to conquer Toril. Kessell would use the Crystal Shard to enslave countless goblinoid tribes and mind-control innocent women to be his {{sex slave}}s. Kessell soon grew bored and, against the advice of Crenshinibon, set loose his armies on the Ten-Towns where thousands where slaughtered, but, proving himself an inept leader, he was outwitted and defeated by Drizzt and the Companions of the Hall. [[TheCorrupter Despite Crenshinibon being known for its corrupting influence]], Akar Kessell proved to be a monster all along who was buried beneath an avalanche by the Crystal Shard when Kessell's own power lust grew too much for even the Shard to handle.

In the ensuing coup, Greeth displayed his evil by releasing ghouls to butcher the people of Luskan and killing thousands when he set his base to explode when he retreated. Even after losing, he was driven by revenge against Duedermont and destroyed supplies needed to feed Luskan's people and burned the ship, the Sea Sprite, to ensure the captain would die in the ruined city. His supposed love for [[TheDragon his Dragon]], Valindra Shadowmantle, was also made moot when he sent her off to die and then raised her as a lich, proving he cared for her only as a tool. While ultimately only a pawn for [[TheManBehindTheMan Jarlaxle]] and [[ManipulativeBastard Kensidan]], the titular Pirate King, Greeth was vile enough that every faction agreed that he needed to be eliminated.

* [[PoliticallyIncorrectVillain Kymil Nimesin]], from the ''Songs & Swords'' series and ''Evermeet: Island of Elves'', both by Elaine Cunningham, is a Sun Elf who [[FantasticRacism utterly despises Moon Elves]] and views the reign of the Moon Elf Moonflower dynasty as the worst atrocity to ever befall Elvenkind. Kymil organizes a conspiracy and begins to have the Moonflower family murdered one by one, including the goodhearted King Zaor and many of his children.

* [[SerialKiller Sougad Lawshredder]], from the ''Harbinger House'' module, is an insane murderer who carved a bloody path of terror through Sigil in his mad quest to [[AGodAmI obtain godhood]]. Sougad was interred in the titular [[BedlamHouse Harbinger House]] because he had a divine spark like all the other residents. A succubus named Nari learned of a powerful artifact that was speeding up the ascensions in Harbinger House and came upon Sougad when she infiltrated it. He told her of an evil ritual that would transform its user into a god, not telling her it only works on those who already have the spark. She releases Sougad to serve as a distraction while she conducts the ritual, while Sougad works on completing it himself. In the ritual, Sougad murders thirteen lawful victims by cutting each one a cumulative number of times, [[AndIMustScream keeping them alive while slicing into them with the needed number of cuts]].

Garond concocted a twofold plan when he found this untamed plane full of animal life. In the beginning, he used magical bowls to capture the souls of the spirits inhibiting the Beastlands. The spirits, taking the forms of sentient animals, were either hunted for sport by Malar's followers or fed to the evil god itself. Either way, the spirits were utterly destroyed when killed outside of the Beastlands. Eventually, Garond sought to move Malar's entire realm to the Beastlands permanently. Discovering a powerful mage called The One communing with the Beastlands itself, he kidnapped a dream hunter and forced her to give The One horrible nightmares of being hunted down and torn to shreds again and again. Connected to the Beastlands, the nightmares began twisting the plane and its inhabitants to savagery and evil, ultimately with the intent to transform the plane into a nightmarish realm worthy of his dark master.

Shar even maintains a tower where she imprisons those who enjoy freedom so she may savor their despair, and during the Time of Troubles she manipulated Selune to destroy her mentally and eventually kill her and all her friends and worshippers. Taking a more proactive role in the modern day, Shar helped to destroy the goddess Mystra and unleash the Spellplague, later having her chief worshippers unleash the Shadow Storm to blanket all Faerun in life-stealing darkness, a prelude to the Cycle of Night where Shar intended on reducing all of creation to nothingness so she may better enjoy the cold, black void yet again.

In ancient days, out of jealousy, she masterminded the betrayal of Dregoth and destruction of his city Guistenal. By far the most chaotic of her peers, Abalach-Re treated Raam like her own personal plaything and allowed chaos and anarchy to reign supreme, but she ensured her people still feared her by forcing anyone she actually deemed a threat to [[InvoluntaryBattleToTheDeath fight to the death]] in Raam's gladiatorial pit. Unique among her peers, she was also a notorious [[SerialRapist rapist]] who forced any man who caught her eye to be her consort before killing him when she grew bored, and any children resulting from these unions were simply [[OffingTheOffspring tossed aside]] as soon as they were born. When not tormenting her people, Abalach-Re committed many atrocities to increase her power base by attempting to enslave the undead of the cursed Black Waters oasis and even attempting the same ritual Kalak created by impersonating an angelic being and sacrificing thousands of good-aligned people in her mad quest to become a Dragon.

After wandering the planes for a time, he set his sights on Sigil, the city at the center of the Multiverse. He quickly usurped leadership of the Fated through blackmail and abused the faction's position as Sigil's tax collectors to gain money and prestige, at the cost of ruining countless lives. Realizing the Lady of Pain was the true master of the city, he planned her downfall by using the ancient Sigil spell to steal control away from her after discovering it from a mage entrapped in the Ebony Gem.

The fiend entraps their souls into gems, which it trades to other fiends to find the Ebony Gem. The traded gems are then given to Ruskin, who either devours the souls within for knowledge or sells them to be used as portal keys. Both processes annihilate the victim's souls and wipe them from existence, something Ruskin both knows and revels in. Ultimately, Ruskin intended to use the Sigil spell to cast down the Lady and absorb all the magic from Sigil, killing everything in the process.
