There's a great deal of debate in some circles on whether JFK was good or bad. He was both. The Kennedy's were old school Illuminati bloodline, so it didn't matter if Nixon or JFK got in as they owned both of them.
JFK ran on a hawkish ticket. He changed his mind during the presidency and tried to sort things out. Some say this was he was having an affair with Mary Pynchon Mayer who gave him his first try of LSD.
That makes a lot of sense. It's a cleansing experience in its purest form. The public nature of his ritual slaying also makes sense in the context of his betrayal to the Luciferians.
