Capricorns are calculated and compulsive, and they will do whatever it takes to succeed. They may also possess a nasty power complex. "As far as serial killers go, they are the most strategic and effective ones."
Sensitive tumours struggle to control their emotions. The fact that they are governed by the moon and that their emotions are based on constantly changing lunar cycles makes them erratic and unpredictable.
Therefore, this could result in violent crimes of passion and explosive outbursts. However, a Cancer is less likely to have planned their murders. "They act impulsively and according to their feelings."
Although Geminis are not among the top serial killers, they are still very strong rivals. They "create adaptive and unsure people, matching the same uncertain spirit of a shifting season," according to another mutable sign.
They also have a lot of charisma and charm, which is "a critical element of a serial killer's perverted modus operandi," according to the book.
Scorpio, like the other water signs, has an emotional side that is dark and dangerous. Scorpios are renowned for their cunning, vengeance, and close-lipped behaviour.
Sagittarians are known for their spontaneity and willingness to take risks. They also give much less thought to the effects and repercussions of their actions.
They may be less adept at hiding their tracks than a Capricorn, but as a mutable sign, "they are significantly more likely to commit a killing than most other signs due to their hedonism and nonchalance."
Pisces, the last sign of the zodiac, has the highest likelihood of being a serial killer. They are "adaptable and quick-thinking persons," which is another mutable indication.
They are therefore a possible recipe for crafty criminals. Particularly sensitive individuals who lead with their emotions and take things personally are pisceans. If a Piscean has a murderous tendency, this can result in some really deadly scenarios.
