Elliot Leyton offered that hypothesis about the motivation of serial killers. His 1986 book Hunting Humans was the first anthropological study of those people. It seems reasonable to propose that increased access in the USA to automatic weapons enabled some would-be serial killers to become mass murderers. In these days when traditional and social media provide a ready-maded Elysian Field for narcissist, it's small wonder that some of these losers take this route to obtain Andy Wahol's 15 minutes of fame.
I wonder whether a key part of the mass killer’s
motivation is to cease being utterly unimportant?
In one act of craziness, he gets total relevance!
