Narcissism and violence: criminological understanding from a homicide case of complete decapitation.

Prompted by a particularly brutal case of homicide, in which the victim was completely decapitated, the authors provide some suggestions for reflection on the theme of narcissistic aggressiveness. Starting from the pathological-forensic analysis of the lesions inflicted, they then examine the role of narcissism from a criminological standpoint, with particular regard to threatened egotism and grandiosity as a trigger of murder. This point of view could help forensic pathologists to understand the psychological aspects of homicide cases.
