Scrolling through TikTok the other day, I stumbled on yet another video ranking serial killers by zodiac sign. The comments were full of “of course it’s a Gemini!” or “Pisces again?!”
It’s a morbidly interesting trend, and as an astrologer with over a decade of experience, I get why people are curious. After all, patterns fascinate us. But most viral videos skip over this: your Sun sign doesn’t define your morality, sanity, or potential for violence.
Astrology is symbolic, not predictive. Your Sun sign is just one piece of a very complex map. At most, it represents your core vitality, not your capacity for harm.
Still, the patterns are hard to ignore. Many of the most infamous serial killers were born under mutable signs: Gemini, Virgo, Pisces, or Sagittarius. These signs are known for adaptability, curiosity, and fluid identity, but in shadow form, that same mutability can twist into moral flexibility, emotional detachment, or a fractured sense of self.
The Sun Sign Isn’t the Whole Person
Your Sun represents your basic identity, the “I am” energy, but it’s only one of hundreds of factors in a birth chart.
Violence, obsession, or lack of empathy aren’t tied to zodiac signs but to chart dynamics, especially when the Moon (emotions), Mars (aggression), Pluto (control), or Saturn (restriction) are in hard aspect to each other.
Someone with a Gemini Sun and a peaceful, well-aspected chart might be a teacher or writer. Another Gemini with a Moon–Pluto–Mars square might wrestle with internal chaos. Same sign, wildly different outcomes.
Astrology doesn’t excuse or predict crime, it only describes energetic patterns that can be expressed in healthy or unhealthy ways, depending on awareness, environment, and free will.
Notable Serial Killers and Their Zodiac Signs
| Sign | Known Killers |
|---|---|
| Gemini | Jeffrey Dahmer, David Berkowitz, Elizabeth Wettlaufer, Peter Sutcliffe, Samuel Little |
| Sagittarius | Ted Bundy, Richard Cottingham, Gary Heidnik, Raymond Fernandez, Richard Speck |
| Virgo | Rodney Alcala, Ed Gein, Richard Angelo, Harrison Graham |
| Scorpio | Charles Manson, Joseph DeAngelo, Belle Gunness, Robert Pickton |
| Pisces | John Wayne Gacy, Aileen Wuornos, Dennis Rader, Richard Ramirez |
Patterns? Maybe. But again, correlation ≠ causation.

The Real Astrology Behind the Pattern
When you dig deeper, the common threads aren’t about signs, they’re about aspects, points, and fixed stars. These often reveal far more about instability, obsession, or emotional suppression than the Sun sign ever could.
Here are some astrological factors that often appear in charts with violent or obsessive themes:
Mars Afflictions
- Mars–Saturn: Frustration and repressed rage.
- Mars–Pluto: Obsession with dominance or control.
- Mars–Moon: Emotional volatility and impulsive reactions.
Pluto Aspects
- Pluto square or opposite Sun/Moon: Deep control issues, power struggles, and difficulty processing emotion.
- Pluto on angles (ASC, MC): Intense, magnetic, sometimes destructive presence.
Saturn–Moon or Saturn–Sun
- Emotional coldness or repression that builds pressure over time.
- When unhealed, can turn into cruelty or emotional detachment.
Lilith and Chiron Involvement
Lilith and Chiron are often overlooked but deeply revealing.
- Lilith (especially conjunct Moon, Mars, or Pluto) can point to repressed anger, sexual trauma, or rage against control.
- Chiron in hard aspect to personal planets often signals unhealed wounding or alienation, not criminality, but deep pain that, if unintegrated, festers.
Fixed Stars & Points
Planets or luminaries aligned with Algol, Antares, or Aldebaran can intensify emotional extremes, not “evil,” but symbolic of powerful, sometimes volatile, archetypal energies.
Real Examples
Jeffrey Dahmer (Gemini) – His Sun wasn’t the cause. The real story lies in his Pluto-square-Sun, Mars in Aries, and 8th-house stellium, showing buried rage, sexual repression, and emotional detachment.
Aileen Wuornos (Pisces) – Her chart showed Moon–Venus–Neptune tension and impulsive Aries energy, creating emotional instability and blurred boundaries between love and aggression.
Their charts tell stories of trauma and distortion — not of “bad signs,” but of unhealed archetypes gone unchecked.

Why It’s Hard to “See” a Killer in a Chart
Serial killers rarely have obvious signatures in their inner or outer planet placements. In fact, someone with a chart full of sextiles and trines, and no harsh aspects to their angles or luminaries, can sometimes be more dangerous or prone to fantasy. Why? Because people with challenging aspects (squares, oppositions, conjunctions to Saturn, Pluto, or Mars) often confront their shadows early in life. They’re forced to grow through hardship, while those with easier charts may never be pushed to integrate their darker impulses.
This is why astrologers can’t (and shouldn’t) use astrology to “spot” killers. What the chart can reveal are psychological patterns, potential for obsession, repression, or intensity, that, when worked with consciously, can transform into creativity, healing, and power instead of destruction.
The Deeper Lesson
Geminis aren’t doomed. Pisces aren’t secretly dangerous. Virgo doesn’t mean “cold.”
Every sign has both light and shadow. What makes the difference is integration. Someone with strong Pluto aspects can become a manipulator or a trauma therapist. Someone with a harsh Mars–Saturn square might project anger outward or channel it into activism, surgery, or sport. And someone with Algol on the Ascendant might keep losing their head in relationships… or, well, you can imagine the darker symbolism there.
Astrology doesn’t create monsters; it gives humans a map. What we do with it is free will.

The Real Astrology of the Human Psyche
If you want to understand psychology through astrology, you have to go deeper than the Sun sign. The Sun may describe your essence, but the story of a person lives in the chart’s shadows and intersections.
- Lilith reveals the hidden impulses, the raw and untamed parts we try to suppress.
- Chiron exposes the wounds we carry and the places that ache for healing.
- Pluto shows how we handle power, control, and transformation.
- Saturn teaches us where fear and repression harden into limitation.
That’s where the real narrative unfolds, not in whether someone happened to be “a Gemini.”
The next time someone jokes that “all Geminis are psychos,” remember: your Sun is just your Sun. And honestly? Gemini deserves a little redemption. Before judging, try understanding, because every sign has a story, and Gemini’s is often the most misunderstood of them all.
