Lima syndrome
An inversion of Stockholm syndrome, called Lima syndrome, has been proposed, in which abductors develop sympathy for their hostages. An abductor may also have second thoughts or experience empathy towards their victims.Lima syndrome was named after an abduction at the Japanese embassy in Lima, Peru, in 1996, when members of a militant movement took hostage hundreds of people attending a party at the official residence of Japans ambassador. Symptoms and behaviors
Victims of the formal definition of Stockholm syndrome develop "positive feelings toward their captors and sympathy for their causes and goals, and negative feelings toward the police or authorities". These symptoms often follow escaped victims back into their previously ordinary lives. Physical and psychological effects
Cognitive: confusion, blurred memory, delusion, and recurring flashbacks. Emotional: lack of feeling, fear, helplessness, hopelessness, aggression, depression, guilt, dependence on captor, and development of post-traumatic stress disorder (PTSD). Social: anxiety, irritability, cautiousness, and estrangement. Physical: increase in effects of pre-existing conditions; development of health conditions due to possible restriction from food, sleep, and exposure to outdoors. Ronald Fairbairns object relations theory of attachment to the abuser
Ronald Fairbairn wrote a complete psychoanalytic model in a series of papers (1940, 1941, 1943, 1944)  which are collected in his 1952 text Psychoanalytic Studies of the Personality. His model explains the surprising psychological reality that abused children become deeply attached to their abusers. He saw that lack of love, chronic indifference and abuse led to a counter-intuitive emotional attachment to the very parent who was abusing them.
If they had access to these memories of themselves, they would inform their conscious ego that they were in a dire, life-threatening situation, information that is too catastrophic to accept. Over time, these memories of themselves in relationship to their rejecting parent coalesce and form internal representations. The process of dissociation of memories of the self and of the parent is called "splitting of the ego" or simply "splitting", because part of the childs original conscious ego (or self) is "split off" from the rest of their normal view of themselves and hidden in their unconscious. Similarly, the memories of that part of the angry, enraged and irritated parent are split off from the "normal" aspects of the parent and held in the unconscious as well. The memories of the angry parent are appropriately called the "Rejecting Object" in Fairbairns model. "Object" is an awkward term used in psychoanalytic theory to designate a person outside the self. So both the terrified memory of themselves and the abusive aspect of the parent (the object) are split off from the conscious self and they become "part selves" and "part objects", The terrified part of the self (called the "Antilibidinal Ego" in Fairbairns model) and the terrorizing part of the object are cut off from consciousness and are no longer associated with the conscious representation of either the self or the object. This affords the child a (false) sense of security that prevents them from feeling anxious about their fate from moment to moment.
