Stalkers are very Dangerous
Stalkers will often denigrate and objectify their victims. This can help stalkers to abuse their victims without experiencing empathy, and may reflect or fuel a belief that they are entitled to behave as they please toward the victims. Viewing victims as "lesser," "weak" or otherwise seriously flawed can support delusions that the victims need to be rescued, or punished, by the stalkers. Stalkers may slander or defame the character of their victims which may isolate the victims and give the stalkers more control or a feeling of power.
Stalkers may use manipulative behavior such as bringing legal action against their victims. They may also attempt to diagnose victims with false mental illnesses. Stalkers may even threaten to commit suicide in order to coerce victims to intervene - all methods of forcing victims to have contact with the stalkers.
Most stalkers are nonpsychotic and may exhibit disorders or neuroses such as major depression, adjustment disorder, or substance dependence, as well as a variety of Axis II personality disorders, such as antisocial, avoidant, borderline, dependent, narcissistic, or paranoia. Some of the symptoms of "obsessing" over a person is part of obsessive compulsive personality disorder. The nonpsychotic stalkers' pursuit of victims can be influenced by various psychological factors, including anger and hostility, projection of blame, obsession, dependency, minimization and denial, and jealousy.
Effects of stalking
Stalking does not consist of single incidents, but is a continuous process. Stalking can be a terrifying experience for victims, placing them at risk of psychological trauma, and possible physical harm. As Rokkers writes, "Stalking is a form of mental assault, in which the perpetrator repeatedly, unwontedly, and disruptively breaks into the life-world of the victim, with whom they have no relationship (or no longer have). Moreover, the separated acts that make up the intrusion cannot by themselves cause the mental abuse, but do taken together (cumulative effect)."
