Ok, then for Oswalds motive , it’s a combination of failure and disappointment to reconcile his marriage PLUS a feeling of betrayal? perceiving JFK having apparently reversed his position about cooperation with USSR with a newspaper report?
So basically Oswald just lost all hope at this point in time which then turned to anger at the JFK whom Oswald had perhaps at one time admired only to perceive JFK at the later time after presumably Oswald reading the paper, that JFK was just the same as Walker, ie.. just another Fascist whom should be shot?
Maybe… if he was Bipolar / schizophrenic which there’s some plausibility to that but just do not have any science like Royal s team to prove it just yet
If he "liked" JFK so much and was such a political person who kept abreast of political matters, why did he have no interest in what happened to JFK outside the place where he worked? According to all accounts he talked to no co-worker about what happened, he inquired to no one about the events (it was chaos outside the TSBD with people running around) and he showed no interest in listening to the radio or watching TV about news about what happened. Nothing.
He returns to his rooming house where the TV is on providing reports on the assassination. Does he stop and watch it? Talk to Roberts about the latest news? Stay around to find out? No, he leaves to go see a movie.
Again: if he admired JFK and was, as is shown, a political person then why act like this? No interest at all?
As towards his views on JFK and the US. We do have this account from a German visitor who talked with Oswald at a party in February of '63: Volkmar Schmidt.
Schmidt said: "Lee Harvey Oswald brought up in the conversation with me the fact that he really felt very angry about the support which the Kennedy administration gave to the Bay of Pigs invasion. It turned out that Lee Harvey Oswald really idealized socialism of Cuba, while he was critical of the socialism in the Soviet Union. And he was just obsessed with his anger towards Kennedy."
Schmidt was interviewed by the FBI shortly after the assassination and never mentions this. So his account is questionable.
Oswald also reportedly complained to the Soviets when he visited their embassy in Mexico City that the US government was after him, that he was being mistreated and that he needed to carry a revolver to protect himself. He said "I am afraid...they'll kill me!!"
