Context:

The explanations developed so far can be used to start answering the questions
surrounding the serial killer’s enigmatic behaviour. We know, from the absence of
ideological framework, that he suffers from acute psychological disturbances which
prevent him from socialising his violence, unlike political criminals, such as the Nazi
leaders. These intense difficulties constitute the first level of a serial killer’s mental
structure. On the second level, organising the chaos, is a rigid authoritarian personality
which enables him to find emotional compensation for his internal disorders through
violence. It is easy to understand that such a mental structure, in itself complex, would
take years to develop, in most cases from childhood, as FBI agent Robert Ressler
remarked: “Let me state unequivocally that there is no such thing as the person who at
age thirty-five suddenly changes from being perfectly normal and erupts into totally evil,
disruptive, murderous behaviour. The behaviours that are precursors to murder have
been present and developing in that person’s life for a long, long time - since childhood.”
( Ressler and Schachtman, 1992, p. 116).
