J.F.K. 50 years

There have been 50 years of just about everything. This coming week, half a century has passed since John F. Kennedy, the 35th President of the United States, was assassinated at 12:30 p.m. Central Standard Time (18:30 UTC) on Friday, November 22, 1963, in Dealey Plaza, Dallas, Texas.
The magnicide shocked the world and severely the United States. The controversy about the responsibility for the death of the president lingers on, as many details fail to accord with the Warren Commission published findings.
The conspiracy theories are now considered by more of two thirds of the American citizens.
Not everybody lamented Kennedy's death. I was astounded, back in 1968, a few weeks after the assassination of Robert Kennedy, hearing one of my superiors saying "...the world was better without him, just like his brother. Now there is just one left of the litter of that bastard of Joe Kennedy..."
The conversation went on over the plan of the Kennedy clan for the three brothers to occupy the presidency consecutively over 24 years and that it should be stopped...
The popularity of the New England brothers was not the same across the US, Particularly in amongst certain Southern states elites they were just a pack of "...damn Yankees, up to no good..."
Another person who claimed having been a classmate of Ted Kennedy at Virginia U., said he had been expelled from Harvard for cheating in his exams, and had bought his admission at Virginia U.
I've always been shocked by the common feeling amongst Americans that the death of someone is a viable way to solve things
The persistence of the death penalty in many states, the relentless use of military force abroad, the widespread ownership of firearms, make the life of people something to be disposed of should the circumstances may warrant it. 
That's part of the background of Kennedy's violent end of his presidency.
Definitely had he survived and continued his mandate and, perhaps, won a second one, many facts of history may have evolved differently. The US intervention in South East Asia for one, would have been different as JFK had just approved the withdrawal of 1000 military advisors in Vietnam. His death prevented it and his successor and the secretary McNamara just went on with what was to be the Vietnam war. 
That sole fact may justify the belief in the existence of a conspiracy to kill JFK, by elements of the military industrial complex.
We may never know. The end of the secrecy applied to documents about the assassination will be in 2017, but is doubtful they may shed any new light. 50 years help any cover up and the interests have not changed that much anyway.
