Ever scrolled through your horoscope and thought, "Man, my sign gets a bad rap"? Well, it might be worse than you think. People love to talk about which signs are the best in bed or the most likely to become millionaires, but there’s a much darker side to the data. If you’ve ever wondered what zodiac sign are most serial killers, the answer isn’t just some spooky campfire story. It’s actually backed by some pretty unsettling statistical analysis.
Honestly, it’s kinda weird how certain signs keep popping up in the police files of history’s most terrifying people. We aren't just talking about the guy who called himself "The Zodiac" either. We're looking at the actual birth charts of hundreds of the most prolific murderers.
The "Big Four" that dominate the crime scene
Most people assume Scorpio would be number one because, let's face it, they have that mysterious, "I might have a body in the basement" vibe. But the data shows a four-way tie for the top spot. According to a massive analysis by Astrology Zodiac Signs, which looked at 485 notorious serial killers, four specific signs account for nearly 40% of the entire list.
The signs? Pisces, Cancer, Scorpio, and Sagittarius.
Each of these signs had 46 killers in the study group. That’s a massive chunk of the pie. If you're a Water sign (Pisces, Cancer, Scorpio), you might want to take a deep breath. Water signs are known for being deeply emotional and intuitive, but when that energy curdles, it seems to turn into something incredibly dark.

Why these signs?
- Pisces: Think about John Wayne Gacy or Richard Ramirez. Pisces are the dreamers of the zodiac. They live in their heads. When a Pisces goes off the rails, that "dream world" can turn into a literal nightmare for anyone around them. They struggle with boundaries, and for a killer, that means the boundary between fantasy and reality just... vanishes.
- Sagittarius: Ted Bundy and Ed Kemper were both Sags. This one usually shocks people because Sagittarians are supposed to be the "fun, travel-loving" friends. But they also have zero filter and a massive need for control and adventure. For someone like Bundy, the "adventure" was the hunt.
- Scorpio: It’s almost a cliché at this point. Charles Manson and Belle Gunness are the poster children here. Scorpios are masters of manipulation. They don't just kill; they control.
- Cancer: Often called the "mother" of the zodiac, which makes their presence here even creepier. Look at Genene Jones, the "Angel of Death" nurse. Cancers are driven by passion and mood swings. If they feel slighted or isolated, that defensive crab shell turns into a weapon.
The deadliest sign you wouldn't expect
While the "Big Four" have the most number of killers, they don’t actually have the highest body count. That "honor" goes to Capricorn.
It’s wild. Capricorns are usually the CEOs and the "boring" workaholics of the world. But statistically, Capricorn serial killers are the most efficient. They might not be as common, but when they do it, they do it a lot. In that same study of 485 killers, Capricorns were responsible for over 800 victims. That averages out to about 19 victims per killer.
Why? Because Capricorns are disciplined. They are patient. They plan. They don't get caught easily because they treat their "hobbies" like a corporate project. Dean Corll, the "Candy Man," is a prime example of this terrifying Capricorn efficiency.
The signs that are (mostly) safe
If you’re a Taurus or a Gemini, you can probably relax. Or at least, your friends can. These two signs are tied for the lowest number of serial killers, with only 27 each in the major studies.

Geminis are often called "two-faced," but it turns out they’re usually too busy talking to actually commit to a long-term murder spree. They might be "scary" in an argument, but they rarely have the focus required to be a serial offender. Taurus, on the other hand, is just too lazy—or rather, too fond of comfort. Killing is hard work, and a Taurus would much rather be on the couch with a weighted blanket and some takeout.
A breakdown of the numbers
If you look at the raw data, the distribution of what zodiac sign are most serial killers looks a bit like this:
- Water Signs (Cancer, Scorpio, Pisces): 28% of all serial killers. They are the "crimes of passion" group.
- Mutable Signs (Gemini, Virgo, Sagittarius, Pisces): These are the most common type of sign for killers. Why? Because mutable signs are adaptable. They can blend in. They can be whoever they need to be to lure a victim.
- The "Deadliest" Average: Capricorn (19 victims per killer), followed by Aquarius (14 victims per killer).
Real-world examples of the "Big Four"
- Pisces: John Wayne Gacy (33 victims), Richard Ramirez (13 victims), Dennis Rader "BTK" (10 victims).
- Sagittarius: Ted Bundy (30+ victims), Ed Kemper (10 victims), Dennis Nilsen (12-15 victims).
- Scorpio: Charles Manson (cult leader/7 victims), Carl Eugene Watts (22+ victims).
- Cancer: Samuel Little (93 confessed victims), Robert Maudsley (4 victims).
Does the Moon sign matter?
Expert astrologers like J. Ruis, who published a statistical analysis of serial killer birth charts, suggest that the Sun sign is only half the story. Most of these individuals have "stressed" charts. This means their planets are in "square" or "opposition" to each other, creating constant internal friction.
A lot of people in the true crime community have noticed that many prolific killers have Mutable Moons or heavy 12th House placements. The 12th House is the house of secrets, mental health, and the "unseen." It’s where the skeletons are kept—literally.

Understanding the limitations
Now, before you go dumping your Sagittarius boyfriend, let’s be real. Astrology isn't a blueprint for murder. Most Sagittarians just want to go hiking and tell you "the truth" even when it hurts your feelings. Most Pisces are just crying in their cars to indie music.
Criminologists like those at the FBI focus on "The Macdonald Triad" (animal cruelty, fire-setting, and bedwetting) rather than birth dates. Astrology is a fun—if slightly morbid—way to look at patterns, but it’s not destiny. Environmental factors, trauma, and brain chemistry are the real drivers.
That said, the statistical overlap is too weird to ignore entirely. It's about the traits of the signs being pushed to an absolute, psychopathic extreme.
Your next steps for a deep dive
If this piqued your interest and you want to see where you—or your "sus" friends—fall on the spectrum, here is how you can look deeper into the data:
- Check your "Big Three": Go to a site like Astro-Charts and plug in your birth time. Look at your Sun, Moon, and Rising signs. If all three are in the "Big Four" (Pisces, Cancer, Scorpio, Sag), you've got the same "astrological DNA" as some of history's most famous killers.
- Look for "Stelliums": A stellium is when you have three or more planets in one sign. If someone has a Scorpio stellium, those "manipulative" and "intense" traits are amplified by 10.
- Examine the 12th House: Check if you have any planets in your 12th House. This is often where the "shadow self" lives.
Knowing what zodiac sign are most serial killers doesn't change who you are, but it definitely makes reading your daily horoscope a lot more interesting. Just remember: if you're a Capricorn, maybe use that "deadly efficiency" for a promotion at work instead of... other things.
