Research by 13 suggests that many serial killers possess elements of psychopathy and antisocial personality disorder (APD), along with symptoms of post-traumatic stress disorder (PTSD).
The most common SMIs are schizophrenia, bipolar disorder and major depression, which have high diagnostic validity (Putkonen et al., 2001; Häkkänen and Laajasalo, 2006) and are the SMIs most consistently linked with homicide (Schanda et al., 2004).
Furthermore, different personality disorders exhibit distinct relationships with criminal behavior. For instance, antisocial and borderline personality disorders, both belonging to Cluster B, are frequently prevalent in criminal populations and often rank as the two most common personality disorders among inmates.
Mission-oriented serial killers consider it their “duty” to rid the world of certain people—sex workers, for instance. Hedonistic killers derive pleasure from killing, either sexual or thrill-based. Other serial killers are driven by a need for power and/or control.
Crimes committed by psychopaths, by contrast, are usually planned and have a pattern. This is why serial killers are often labeled as psychopaths, as many of them can appear normal and even charming on the outside while being cold-hearted and calculating on the inside.
Holmes and DeBurger (1998) have provided a typology that divides serial killers into four broad types: visionary, mission-oriented, hedonistic, and power/control. These are not definitive categories; many serial killers may evidence aspects of all types at various times.
The revised version of the checklist includes the following characteristics:
BPD Meltdown
During a meltdown, people may experience extreme mood swings, impulsivity, and difficulty calming down. Understanding how BPD contributes to meltdowns is crucial for developing coping strategies and providing support to manage and navigate these overwhelming emotional experiences.
Narcissistic breakdown symptoms can include rage, impulsive behaviors, or other ways of showcasing intense mental suffering. A narcissist will lash out at you in any way they can or hurt themselves to cope with the shame.
Symptoms
People with Borderline Personality Disorder (BPD) split as a subconscious defense mechanism to cope with overwhelming emotions, particularly fear of abandonment and intense feelings of anxiety, by viewing themselves, others, or situations in black-and-white, all-or-nothing terms (good vs. bad) instead of integrating complex, contradictory qualities. This protects them from pain by simplifying a confusing world, but it leads to rapid shifts between idealizing someone as perfect and devaluing them as terrible, often after minor perceived slights or triggers.
Serial killers often lack empathy and guilt, and most often become egocentric individuals; these characteristics classify certain serial killers as psychopaths. Serial killers often employ a “mask of sanity” to hide their true psychopathic tendencies and appear normal, even charming.
Anorexia Nervosa – Highest Mortality Rate of Any Mental Disorder: Why? While all eating disorders are dangerous mental health conditions, anorexia nervosa (AN) has the unfortunate distinction of being the deadliest eating disorder—and, by some accounts, the deadliest psychiatric disorder.
Generalized Anxiety Disorder (GAD): One of the most common mental disorders, GAD is characterized by excessive worry about issues and situations that individuals experience every day. Any worrying that is out of proportion to the reality of the situation may fall under this disorder.
People with borderline personality disorder have a strong fear of abandonment or being left alone. Even though they want to have loving and lasting relationships, the fear of being abandoned often leads to mood swings and anger. It also leads to impulsiveness and self-injury that may push others away.
9 Signs of Borderline Personality Disorder (You Need to Know)
Don't…
A great deal of research suggests that the core, precipitating features of psychopathy are developmental in nature, with relatively persistent traits becoming apparent before the age of 10; furthermore, it seems these traits are predicated by significant genetic risk factors (Viding et al., 2005; 2008).
They just don't care. The more you tell a psychopath how sad you were or how hurt you got, only few, that'll be more tools to make the situation even worse. You should never tell a psychopath how you feel about it because they will use this information in order to use you. That's just the way it is.
Common signs of a sociopath
Antisocial personality disorder
It's also been diagnosed among three of the most ruthless American serial killers: Ted Bundy, an infamous killer and necrophile, confessed to 30 murders in the 1970s. John Wayne Gacy, known as the “Killer Clown,” raped and killed 33 boys and young men in the 1970s.
