In discussing the problem of mass murder an ever increasing expression
of violence in society, the typology of the perpetrators of such crim
es is presented. Illustrations of some of the most notorious killers a
re provided and the unique case of a mass murderer who left, as a suic
ide ''note,'' a videotaped soliloquy is presented. The dynamics of mas
s murder and of mass murder-suicide are discussed; the killings are vi
ewed as the outcome of deep frustration and perceived rejection in a h
ighly narcissistic person, wounded in his ego, hostile towards society
, and in search of identity and notoriety through a cathartic self ass
ertion. Similarities are shown between the mass murderer and the mytho
logical Norse ''berserk'' and it is speculated that the superman compl
ex may be at the core of the killer's behavior It is contended that th
e personal psychopathology of the killer is determinant of the destruc
tive behavior although social factors are highly contributory. (C) 199
