I was scrolling through TikTok the other day, and I came across a video about serial killers and their zodiac signs. I’ve been into astrology for over a decade, but I’d never really thought to dig into what serial killers might have in common astrologically. But this video? It caught my attention because it pointed out that a lot of these infamous killers were Pisces, Geminis, or Virgos.
The interesting thing is that all three signs are mutable, which means they’re super adaptable and changeable. Plus, they all have this theme of duality running through them. Geminis are symbolized by twins, which is pretty much the ultimate duality. Pisces? Two fish swimming in opposite directions. And Virgo, even though it’s just one virgin, is ruled by Mercury—the planet of communication, which also has this dual nature.
Notable Serial Killers & Their Zodiac Signs
It’s definitely intriguing to look at the zodiac signs of famous serial killers, even though astrology obviously shouldn’t be used to justify or explain their crimes. When we talk about their signs, though, we’re really only looking at their sun signs, which is just one piece of the puzzle. It doesn’t give the full picture, but it can reveal some interesting patterns—even if they’re just coincidental.
Take the Zodiac Killer, for example. He terrorized Northern California in the late 1960s and was never caught, but people have speculated about his sign based on the timing of his crimes. Some think he might’ve been a Scorpio or Sagittarius, since those signs align with the periods when the murders happened. It’s all speculation, of course.
Then there’s Jeffrey Dahmer, one of the most infamous serial killers, who even had documentaries and movies made about him. He was a Gemini, but here’s the thing: his Gemini sun was at 0 degrees, which is considered a critical degree in astrology. That alone adds a layer of intensity. Plus, his Moon and Mars were both in fiery Aries, which honestly feels like it fits his personality and actions way more than just his Gemini sun.
And what about Aileen Wuornos? Her case is so complex. Even though she killed multiple men, a lot of people felt sympathy for her and were conflicted about her death sentence. She claimed she acted in self-defense after being abused by the men she killed. Astrologically, she had her Sun in gentle, empathetic Pisces, but that was her only Pisces placement. Her Venus was in bold, impulsive Aries, and her Moon was in Libra—a sign all about balance and relationships. But with challenging aspects between those placements, it’s easy to see how her life became such a tragic story.

Gemini And Pisces: The Most Common Signs
Geminis and Pisces often come up in discussions about serial killers and their zodiac signs. Now, obviously, being a Gemini or a Pisces doesn’t cause someone to become violent—but these signs do have certain traits that can, interestingly enough, align with some behaviors seen in serial killers.
Take Geminis, for example. They’re known for their dual nature, which can make them incredibly complex and multifaceted. Geminis are always thinking, analyzing, and planning—traits that could, in theory, lend themselves to the meticulous planning often required for committing multiple murders.
Serial killers need to be calculated and detail-oriented, and Geminis, being natural thinkers, might have the mental capacity to carefully plot out their actions. Plus, as a sign of communication, it’s not surprising that some Gemini serial killers have left behind manifestos, letters, or notes detailing their plans or motives. It’s like their need to express themselves spills over into their crimes.
Pisces, on the other hand, are often seen as empathetic and sensitive, but they also have a darker, more elusive side. Their emotional depth and ability to blend into different situations could make them skilled at manipulating or hiding their true intentions. While this doesn’t mean Pisces are prone to violence, it’s interesting how these traits might play out in extreme cases.
Pisces are the dreamers of the zodiac, always lost in their own world of thoughts and emotions. Since Pisces rules the 12th house, which is all about the unknown, illusions, and hidden depths, it’s not hard to see how a Pisces serial killer might spend years fantasizing about their crimes before actually acting on them. For them, it’s like this dark, secret world they’ve built up in their mind, something they’ve imagined over and over again.
When they finally take action, it’s often less about anger or revenge and more about wanting to step into that forbidden, out-of-the-ordinary experience they’ve been obsessing over. Their crimes can feel almost like they’re driven by a twisted sense of curiosity or a need to bring their fantasies to life.
Astrology Aspects That Make Someone A Serial Killer
While astrology can offer some interesting insights and guidance, it’s important to remember that it can’t definitively predict violent behavior—or any behavior, for that matter. At the end of the day, we all have free will to choose our own path and make our own decisions. That said, over the years, certain astrological aspects have been loosely linked to a potential for violence or intense behavior. But here’s the thing: even if someone has those aspects in their chart, it doesn’t mean they’re destined to act on them.
Algol-Moon Conjunction
Algol, often referred to as the “Demon Star,” is one of the most infamous stars in astrology. Located in the constellation Perseus, it’s actually a binary star system—two stars orbiting each other—which makes it appear to blink or flicker in the night sky. This eerie quality has contributed to its dark reputation.
In astrological terms, Algol is associated with some pretty intense and unsettling themes. It’s often linked to bad luck, violence, and overwhelming emotions, usually of a negative variety. Think power struggles, loss, and danger—the kind of energy that makes you want to double-check your chart if it shows up prominently. Its symbolism ties back to the Greek myth of Perseus cutting off Medusa’s head, which adds to its association with sudden, dramatic, and even destructive events.
When Algol is conjunct the Moon in someone’s chart, it can amplify emotional intensity in a way that’s hard to ignore. This placement is sometimes linked to violent outbursts, especially when emotions are involved. It’s also said to point to a difficult relationship with the mother or early childhood trauma involving maternal figures. People with this aspect might struggle with deep-seated anger, instability, or even misogynistic tendencies, as their emotions can become all-consuming and hard to manage.
Afflictions To Mars
Mars is all about aggression, raw energy, and that primal drive to take action. When it forms challenging aspects—like squares or oppositions—with other planets, especially heavy hitters like Saturn, the Moon, or Pluto, it can point to a personality that struggles with violent tendencies or explosive anger.
For example, Mars clashing with Saturn (the planet of frustration, limits, and discipline) can create a buildup of pent-up rage. It’s like constantly hitting a wall, which can lead to outbursts when the pressure becomes too much. On the other hand, Mars in tension with Pluto (the planet of power, transformation, and destruction) can indicate someone who’s drawn to control, dominance, or even destructive behavior. This aspect can suggest a deep, buried anger that simmers beneath the surface, sometimes erupting in intense or cruel ways.
And then there’s Mars opposing or squaring the Moon, which ties emotions directly to that aggressive Martian energy. This can make someone’s feelings incredibly volatile, with moods shifting rapidly and anger flaring up in response to emotional triggers. It’s like their emotions are constantly at war with their impulses, making it hard to keep those hostile urges in check.
Pluto Aspects
Pluto’s all about intensity—power, transformation, and digging into our shadow sides. When it’s strongly connected to personal planets like the Sun, Moon, Mars, or Venus in someone’s chart, it can show a person who’s deeply tied to themes of control, domination, and even destructive behaviors if they’re not careful.
Pluto’s energy isn’t inherently bad, though—it’s about uncovering what we need to transform within ourselves. It’s like a cosmic spotlight on the parts of us that need healing or growth, even if the process feels heavy or challenging.
Saturn-Moon Aspects
When Saturn and the Moon are in a tense aspect—like a square or opposition—it can feel like your emotions are stuck in a deep freeze. You might struggle to express how you feel in a healthy way, coming off as reserved, detached, or even a little cold. But underneath that calm exterior, there’s often a lot bubbling beneath the surface—unresolved issues, past hurts, or emotional baggage that hasn’t been dealt with. This tension can sometimes lead to acting out in unhealthy ways, like bottling things up until they explode or shutting down entirely.
Stelliums or Strong Emphasis In Scorpio/8th House
Scorpios are all about intensity and passion—they’re the sign of transformation and deep, powerful emotions. Ruled by Mars (traditionally) and Pluto (modern), they’ve got this magnetic personality that draws people in, and they’re often fascinated by exploring the deeper, darker, or even taboo sides of life. If someone has a lot of planets or key placements in Scorpio (or the 8th house), they’re probably the type who’s always pondering life’s big mysteries. Think topics like death, the afterlife, or the hidden motivations behind human behavior—they’re drawn to what lies beneath the surface.
That intensity is their superpower—it gives them incredible depth and insight. But, yes, it can also pull them into darker places if they’re not careful. Scorpios feel everything deeply, and that can be both a gift and a challenge. When they channel that energy positively, though, they’re unstoppable. They’re the ones who aren’t afraid to face the shadows, both in themselves and in the world around them.
Afflicted Sun or Moon
When the Sun or Moon—aka the “luminaries”—are afflicted by tough aspects from planets like Saturn, Pluto, or Uranus, it can point to some deep-seated struggles. The Sun represents our vitality, father, core identity and sense of self, while the Moon rules our emotions, feelings, mother, and instincts. If these two are under pressure, it can mess with how we see ourselves, how we process our feelings, and even how we connect with others.
For example, hard aspects to the Sun can make it really challenging to feel grounded in your identity or confident in who you are. This might also point to struggles with authority figures, like your father, or even a general distrust or resentment toward men, depending on how those energies play out. On the other hand, a challenged Moon can bring emotional turbulence—think mood swings, difficulty trusting your instincts, or even strained relationships with your mother or women in general. These dynamics can leave you feeling emotionally unmoored or disconnected.
When heavy hitters like Pluto (power, control) or Saturn (restriction, fear) are involved, these issues can get amplified. Pluto can bring up intense, obsessive, or controlling tendencies, while Saturn might layer on feelings of frustration or fear. If these energies aren’t managed well, they can sometimes lead to darker behaviors, like a need for dominance or even sadistic tendencies.
Final Words
This article was all in good fun—it was not meant to be taken too seriously! Astrology is a great tool for self-reflection and exploration, but it’s definitely not a reason to judge or label someone based solely on their zodiac sign. That said, if you’re into true crime or find serial killers an intriguing topic, diving deeper into their full birth charts might offer some interesting insights.
For example, planets at critical degrees (like 0, 18, 22, or 29 degrees) can add intensity to a chart, and houses like the 8th (transformation, power) and 12th (hidden matters, the subconscious) often play a big role in these kinds of extreme behaviors. Challenging aspects between heavy planets like Pluto, Saturn, Mars, and the Moon—or even Mercury, which rules communication—can also reveal patterns worth exploring. But remember, it’s always about looking at the whole chart, not just one piece. Astrology is complex, and so are people!
