However, experts emphasize that having psychopathic tendencies does not directly lead to criminal behavior.

That Person in Your Messenger, Could They Be a Psychopath?
A research study has found that you can gauge certain personality traits
just by analyzing the words someone uses in a message chat window.
"The everyday words people choose quietly but clearly reveal their way of thinking, emotional state,
and how they relate to others."
- Charlotte Entwistle, Researcher, Department of Psychology, University of Liverpool
"From short text messages to long emails, private conversations with friends,
and even online comments, a person's psychological characteristics are embedded in their language patterns."
"When hostility, extreme negativity, and emotional or cognitive rigidity are repeatedly displayed,
these may be early signs of 'dark traits' such as psychopathy or narcissism."
According to this research, language habits that frequently use swear words or repeatedly express negative emotions such as "angry," "crazy," "dislike"
are highly likely to be associated with impulsivity and low empathy.
It is especially important to be cautious if such expressions appear excessively, even in trivial situations.
Another key sign is the use of self-centered and obsessive language.
Phrases like "I need this," "I must do this," and "I am right" are frequently used,
while words that indicate relationships and solidarity, such as "we," "together," and "each other," are rarely used.
This may suggest a lack of empathy or a hidden desire for dominance.

This Is Also Evident in 'Letters from Serial Killers'
Researcher Entwistle cited the letters of Austrian serial killer
Jack Unterweger as a real-life example.
His writings were overwhelmingly self-centered, focusing on "I,"
and his emotional expressions were excessively dry and calculated.
The letters of American serial killer Dennis Rader (Dennis Rader, BTK Killer)
also prominently featured exaggerated, cold, and dominance-seeking language.
"You don't need to analyze every single word someone says,
but persistent language patterns that make you uncomfortable
can be important signals to protect yourself."
can be important signals to protect yourself."
"It is highly likely that these language patterns were already formed before any crime occurred."

Psychopaths are characterized by a lack of empathy, absence of guilt, impulsivity, and superficial charm,
but some demonstrate outstanding qualities in business, politics, and finance, and function well in society.
