http://www.psychohistory.com/There are some interesting essays by psychologists exploring a theory very near to what you've stated. I found it to be very chilling stuff, often passed along cultually and generationally- and something that is often exploited by demogougues in mass outbreaks of violence, war, etc.
Edit to add, interesting quotes in a chapter of a book on that site entitled, The Emotional Life of Nations
by Lloyd deMause
From chapter 2, The Assasination of Leaders:
Americans from all parties were furious with Kennedy for various pretexts. Many began calling for a new Cuban invasion, agreeing with Barry Goldwater's demand that Kennedy "do anything that needs to be done to get rid of that cancer. If it means war, let it mean war."20 Kennedy was accused of being soft on Communism for living up to his no-invasion pledge to the Soviets, and when he then proposed signing a Limited Nuclear Test Ban Treaty with them, his popularity dropped even further.21
The nation's columnists expressed their fury towards the president, and
1:2 America felt death wishes toward Kennedy for not starting a war with Cuba
political cartoonists pictured Kennedy with his head being chopped off by a guillotine (above). Richard Nixon warned, "There'll be...blood spilled before
over,"22 and a cartoon in The Washington Post portrayed Nixon digging a grave. Many editorialists were even more blunt. The Delaware State News editorialized: "Yes, Virginia, there is a Santa Claus. His name right now happens to be Kennedy let's shoot him, literally, before Christmas."23 Potential assassins all over the country-psychopaths who are always around looking for permission to kill-saw all these media death wishes as signals, as delegations to carry out a necessary task, and began to pick up these fantasies as permission to kill Kennedy.24
