A person with a borderline personality disorder often experiences a repetitive pattern of disorganization and instability in self-image, mood, behavior and close personal relationships. This can cause significant distress or impairment in friendships and work. A person with this disorder can often be bright and intelligent, and appear warm, friendly and competent. They sometimes can maintain this appearance for a number of years until their defense structure crumbles, usually around a stressful situation like the breakup of a romantic relationship or the death of a parent.

The increased frequency of borderline disorders among women may also be a consequence of the greater incidence of incestuous experiences during their childhood. This is believed to occur ten times more often in women than in men, with estimates running to up to one-fourth of all women. This chronic or periodic victimization and sometimes brutalization can later result in impaired relationships and mistrust of men and excessive preoccupation with sexuality, sexual promiscuity, inhibitions, deep-seated depression and a seriously damaged self-image. There may be an innate predisposition to this disorder in some people. Because of this there may ensue subsequent failures in development in the relationship between mother and infant particularly during the separation and identity-forming phases of childhood.

Relationships with others are intense but stormy and unstable with marked shifts of feelings and difficulties in maintaining intimate, close connections. The person may manipulate others and often has difficulty with trusting others. There is also emotional instability with marked and frequent shifts to an empty lonely depression or to irritability and anxiety. There may be unpredictable and impulsive behavior which might include excessive spending, promiscuity, gambling, drug or alcohol abuse, shoplifting, overeating or physically self-damaging actions such as suicide gestures. The person may show inappropriate and intense anger or rage with temper tantrums, constant brooding and resentment, feelings of deprivation, and a loss of control or fear of loss of control over angry feelings. There are also identity disturbances with confusion and uncertainty about self-identity, sexuality, life goals and values, career choices, friendships. There is a deep-seated feeling that one is flawed, defective, damaged or bad in some way, with a tendency to go to extremes in thinking, feeling or behavior. Under extreme stress or in severe cases there can be brief psychotic episodes with loss of contact with reality or bizarre behavior or symptoms. Even in less severe instances, there is often significant disruption of relationships and work performance.

…they were raised in environments in which their beliefs about themselves and their environment were continually devalued and invalidated. These factors combine to create adults who are uncertain of the truth of their own feelings and who are confronted by three basic dialectics they have failed to master (and thus rush frantically from pole to pole of):

Kernberg believes that borderlines are distinguished from neurotics by the presence of "primitive defenses." Chief among these is splitting, in which a person or thing is seen as all good or all bad. Note that something which is all good one day can be all bad the next, which is related to another symptom: borderlines have problems with object constancy in people -- they read each action of people in their lives as if there were no prior context; they don't have a sense of continuity and consistency about people and things in their lives. They have a hard time experiencing an absent loved one as a loving presence in their minds. They also have difficulty seeing all of the actions taken by a person over a period of time as part of an integrated whole, and tend instead to analyze individual actions in an attempt to divine their individual meanings. People are defined by how they lasted interacted with the borderline.

…projection of unpleasant characteristics in the self onto others and projective identification, a process where the borderline tries to elicit in others the feelings s/he is having.

Alternating clinging and distancing behaviors (I Hate You, Don't Leave Me). Sometimes you want to be close to someone. But when you get close it feels TOO close and you feel like you have to get some space. This happens often. Great difficulty trusting people and themselves. Early trust may have been shattered by people who were close to you. Sensitivity to criticism or rejection. Feeling of "needing" someone else to survive Heavy need for affection and reassurance Some people with BPD may have an unusually high degree of interpersonal sensitivity, insight and empathy.

People with BPD are often bright, witty, funny, life of the party. They may have problems with object constancy. When a person leaves (even temporarily), they may have a problem recreating or remembering feelings of love that were present between themselves and the other. Often, BPD patients want to keep something belonging to the loved one around during separations. They frequently have difficulty tolerating aloneness, even for short periods of time. Their lives may be a chaotic landscape of job losses, interrupted educational pursuits, broken engagements, hospitalizations. Many have a background of childhood physical, sexual, or emotional abuse or physical/emotional neglect.

…their attitudes towards family, friends, and loved ones may suddenly shift from idealization (great admiration and love) to devaluation (intense anger and dislike). Thus, they may form an immediate attachment and idealize the other person, but when a slight separation or conflict occurs, they switch unexpectedly to the other extreme and angrily accuse the other person of not caring for them at all.

Even with family members, individuals with BPD are highly sensitive to rejection, reacting with anger and distress to such mild separations as a vacation, a business trip, or a sudden change in plans. These fears of abandonment seem to be related to difficulties feeling emotionally connected to important persons when they are physically absent, leaving the individual with BPD feeling lost and perhaps worthless

many, but not all individuals with BPD report a history of abuse, neglect, or separation as young children.⁸ Forty to 71 percent of BPD patients report having been sexually abused, usually by a non-caregiver.⁹ Researchers believe that BPD results from a combination of individual vulnerability to environmental stress, neglect or abuse as young children, and a series of events that trigger the onset of the disorder as young adults. Adults with BPD are also considerably more likely to be the victim of violence, including rape and other crimes.

Psychopathy is a concept subject to much debate, but is usually defined as a constellation of affective, interpersonal, and behavioral characteristics including egocentricity; impulsivity; irresponsibility; shallow emotions; lack of empathy, guilt, or remorse; pathological lying; manipulativeness; and the persistent violation of social norms and expectations (Cleckley 1976; Hare 1993). The crimes of psychopaths are usually stone-cold, remorseless killings for no apparent reason. They cold-bloodedly take what they want and do as they please without the slightest sense of guilt or regret. In many ways, they are natural-born intraspecies predators who satisfy their lust for power and control by charm, manipulation, intimidation, and violence. While almost all societies would regard them as criminals (the exception being frontier or warlike societies where they might become heroes, patriots, or leaders), it's important to distinguish their behavior from criminal behavior. As a common axiom goes in psychology, MOST PSYCHOPATHS ARE ANTISOCIAL PERSONALITIES BUT NOT ALL ANTISOCIAL PERSONALITIES ARE PSYCHOPATHS. This is because APD is defined mainly by behaviors (Factor 2 antisocial behaviors) and doesn't tap the affective/interpersonal dimensions (Factor 1 core psychopathic features, narcissism) of psychopathy. Further, criminals and APDs tend to "age out" of crime; psychopaths do not, and are at high risk of recidivism. Psychopaths love to intellectualize in treatment with their half-baked understanding of rules.

List of Common Psychopathic Traits

In addition to these most well-known types, there have been criminologists who have put forward additional constructs. They are only mentioned here because of their relevance to serial criminals, and the interesting similarity in the way they compare to the FBI's "disorganized - organized" typology.

Psychopaths cannot be understood in terms of antisocial rearing or development. They are simply morally depraved individuals who represent the "monsters" in our society. They are unstoppable and untreatable predators whose violence is planned, purposeful and emotionless. The violence continues until it reaches a plateau at age 50 or so, then tapers off. Their emotionlessness reflects a detached, fearless, and possibly dissociated state, revealing a lower autonomic nervous system and lack of anxiety. It's difficult to say what motivates them - control and dominance possibly - since their life history will usually show no bonds with others nor much rhyme to their reason (other than the planning of violence). They tend to operate with a grandiose demeanor, an attitude of entitlement, an insatiable appetite, and a tendency toward sadism. Fearlessness is probably the prototypical (core) characteristic (the low-fear hypothesis). It's helpful to think of them as high-speed vehicles with ineffective brakes. Certain organic (brain) disorders and hormonal imbalances mimic the state of mind of a psychopath.

In truth, psychopathy knows no boundaries.

First of all, it is found among all social classes. Such character disordered people are not only the charming con men and dangerous gold diggers that Dr. Hare warns us about, not only are they the lower-class, drunken, drug abusing "sociopaths" which Dr. Black writes about, they are also people who hold high positions in society, as Jungian author Guggenbuhl-Craig has said, because those who cannot love want power.

Some may disagree, but it has been well known that the socially adept psychopath, while his personal life may lie in disarray, is not incapable of reaching the heights of power (Hitler was a very good example of this). Hervey Cleckley also wrote about the socially adept psychopath in great detail.
