television 8217 s: Dark Delights of the Small Screen
10 Lon Suder: Star Trek Voyager
Brad Dourif, a veteran of both television and film, brings a terrifying edge to the Betazoid Lon Suder in Star Trek Voyager. Known for his unsettling roles—think Wormtongue in The Lord of the Rings—Dourif makes Suder especially chilling. Imagine a Betazoid, a species famed for empathy, who instead thrives on killing purely for amusement. That contrast alone sends shivers down any fan’s spine.
Suder first appears in the season‑two episode “Meld,” and viewers instantly sense something amiss. Stranded aboard Voyager, far from home, Suder fills his endless days by murdering his crewmates, openly admitting his sole motive is boredom. This stark departure from the typical Starfleet ideal makes his presence all the more disturbing.
When Tuvok attempts a mind‑meld to understand Suder, he inadvertently absorbs the Betazoid’s violent cravings. Though a year in the brig tempers Suder somewhat, his appetite for blood never fully vanishes. He ultimately meets his end battling a Kaison warrior, finally channeling his murderous instincts into a heroic sacrifice for Voyager.
9 Norman Bates: Bates Motel
Norman Bates, the infamous figure behind Alfred Hitchcock’s classic Psycho, gets a modern makeover in the television series Bates Motel. The show, which aired on A&E beginning in 2013, delves deep into the formative years that shaped Norman’s twisted psyche, offering a fresh perspective on the notorious killer.
Central to the series is Norman’s unsettling bond with his mother, Norma, a relationship that borders on the pathological. After the death of Norman’s father, Norma purchases a remote motel in White Pine Bay, Oregon, setting the stage for a chilling exploration of how Norman’s mind unravels during his teenage years. Over the five‑year run, his body count swells dramatically, while the ever‑present specter of his mother may be either aiding or obscuring his crimes.
Hitchcock suggested that an over‑protective mother drove Norman to madness—a theory the series expands upon, hinting that perhaps Norma herself is complicit, or even the mastermind behind the murders. Either way, Norman Bates remains one of television’s most relentless serial killers.
8 Benjamin Linus: Lost
Benjamin Linus, the manipulative mastermind of Lost, has a long‑standing record of bloodshed in the name of “the Island.” He orchestrated the massacre of the entire Dharma Initiative, even watching his own father die in excruciating agony, and personally took the lives of fourteen others, including John Locke.
Linus constantly claims to act for the Island’s greater good, but his true loyalty lies only with himself. He even permits his own daughter’s death rather than surrender to mercenaries, showcasing a chilling willingness to sacrifice anyone for his own power. Although he later assists Hurley in restoring balance to the Island, his legacy remains stained with lies, murders, kidnappings, and brutal torture—all driven by selfish ambition rather than any noble cause.
7 Joe Goldberg: You
The series You epitomizes today’s fascination with tech‑savvy stalkers. Joe Goldberg, a seemingly ordinary New York City bookstore manager, becomes obsessively infatuated with aspiring writer Guinevere Beck. He weaponizes social media—Facebook, Instagram—to isolate her, eliminating friends and exes to clear a path for his twisted version of love.
As the show progresses through four seasons, Joe’s dark past unravels: he once buried his ex‑girlfriend Candace alive, and his killing spree expands across the country, tallying roughly fifteen victims from New York to California. He even marries and fathers a child with a fellow killer, Love, only to murder her later on.
Charismatic and outwardly normal, Joe’s relentless obsession invariably culminates in murder. His unending spree makes him one of television’s most merciless killers, proving that charm can mask a dangerously lethal soul.
6 Bloody Face: American Horror Story
Oliver Thredson, better known as Bloody Face, is the terrifying antagonist of American Horror Story. Abandoned by his mother and raised in an orphanage, he later attends medical school, where his fascination with cadavers morphs into a macabre obsession with women whose skin resembles his mother’s.
Thredson kidnaps, flays, and beheads his victims, fashioning their skin into furniture and a grotesque mask dubbed “Bloody Face.” To the outside world, he appears as a calm, compassionate physician, yet beneath that façade lies a brilliant, unhinged, and blood‑thirsty predator. The original Bloody Face’s reign began in the 1960s, spawning copycats, including a second Bloody Face—Johnny Morgan—whose combined body count remains largely unknown. Both meet their demise at the hands of Lana Winters, who shoots them in the back of the head.
5 Hannibal Lecter: Hannibal
While Anthony Hopkins immortalized Hannibal Lecter in the classic film Silence of the Lambs, the television series Hannibal expands the legend with Mads Mikkelsen delivering a chillingly elegant performance. The series follows the brilliant psychiatrist who doubles as a cannibalistic serial killer.
Lecter, serving as an FBI consultant, exploits his position to delve into the mind of other killers, all while indulging his own gruesome appetites. He not only murders his victims but also savors them by consuming their flesh. His relationship with FBI agent Will Graham gives him a strategic edge, allowing him to outmaneuver authorities and continue his murderous feasts for sheer pleasure.
4 Arthur Mitchell: Dexter
In the hit series Dexter, the “Trinity Killer”—Arthur Mitchell, portrayed by John Lithgow—stands out as a particularly chilling antagonist. On the surface, Mitchell appears as a charitable home‑builder and devoted family man, yet he follows a ritualistic pattern of three murders, each echoing a traumatic event from his childhood.
The cat‑and‑mouse game between Mitchell and Dexter intensifies throughout season four, culminating in a brutal showdown where Dexter slams a hammer into Mitchell—the very method Mitchell used on his third victim. Tragically, before Mitchell meets his end, he murders Dexter’s wife, Rita, leaving their son Harrison drenched in blood, a haunting echo of Dexter’s own origin story.
Mitchell’s complex backstory, combined with Lithgow’s masterful performance, cements him as one of television’s most ruthless villains, a perfect blend of domestic normalcy and cold‑blooded murder.
3 Walter White: Breaking Bad
Walter White, the once‑mild‑mannered high school chemistry teacher turned drug kingpin, epitomizes the transformation from ordinary to monstrous. Early in Breaking Bad, his first victim, Emilio, dies in self‑defense, but the true turning point arrives when he murders Krazy‑8, a decision that haunts him for two episodes before he finally embraces his darker self.
By the series’ climax, Walter has evolved into a merciless drug lord, eliminating anyone—friends, foes, and even close allies like Mike—to protect his empire. His body count swells to nearly three hundred, a staggering number that underscores his evolution into a ruthless serial killer.
Walter’s descent showcases how ambition, pride, and desperation can morph a seemingly benign individual into a serial murderer, making him a cornerstone of television’s most chilling anti‑heroes.
2 Dexter Morgan: Dexter
The eponymous hero‑turned‑anti‑hero of Dexter is perhaps the most iconic television serial killer. Discovered as a child in a pool of blood after his mother’s murder, Dexter grows up under the tutelage of his adoptive father, Harry, who teaches him a strict “code” that permits only the killing of fellow murderers.
By day, Dexter works as a blood‑spatter analyst for the Miami Police Department, a role that grants him insider access to investigations and keeps him one step ahead of law enforcement. His code, however, restricts his victims to those who have escaped justice, leading to countless tense confrontations throughout the series’ eight‑season run, later extended by Dexter: New Blood in 2021.
Over the course of the show, Dexter amasses 144 confirmed kills, with the potential for many more undisclosed murders. His methodical efficiency and cold calculation cement his reputation as a ruthless yet oddly principled killing machine.
1 The Lopper: Seinfeld
The season‑nine finale of Seinfeld introduces a chilling, unnamed serial killer known only as the Lopper, who stalks New York’s Riverside Park. Though the series is famed for its comedic “show about nothing,” this dark subplot adds a startlingly grim twist to the otherwise light‑hearted narrative.
The Lopper’s modus operandi involves brutally decapitating victims, leaving audiences to wonder about the killer’s identity. Theories abound—some point to Cousin Jefferey, others to the eccentric Joe Davola, and still others suggest the enigmatic “Slippery Pete.” To this day, the true nature of the Lopper remains a haunting mystery, underscoring how even comedy can brush against the macabre.
