The JFK conspiracy theroy is just not allowed.

68. IMO, Oswald is easy to figure out in hindsight.

He was a narciscist. He thought he was destined for great things, and society refused to recognize his greatness. And his repeated failures created dissonance, and caused him to become increasingly violent and unstable.

What we know:
As a teen, he started studying Marxism to appear an intellectual. He quit 10th grade to join the Marines...his brother was in Armed Services and respected, so he thought he would be too. His Marine career was a failure...he was court-martialled twice, spent another stint in the brig, demoted, and eventually discharged. Marines probaly happy to see him go. So, surely Russia would welcome such a great man with open arms, right? Not exactly. Russia gave him a one week tourist visa. On the day his official escort was supposed to deliver him to the airport, he slashed his wrists so his stay could be extended by a stint in the hospital. Somehow, he convinced the Russians to let him stay. Thinking that he's probably a CIA plant, Russia ships him off to a toaster factory in remote Minsk, where he's watched 24/7 by the KGB. This is hardly the treatment that such a great man deserves. Russia, home of Marxism, no less! So he becomes disillusioned with Russia and decides to return to the US. He's still a US citizen (despite earlier attempts to renounce his citizenship), so the US can't refuse him. Settling in New Orleans (after extensive questioning by CIA, FBI, and State Dept) he decides to take up the cause of Castro. He attempts to start a Pro-Castro chapter in NOLA, but is turned down by the national office. They just send him literature instead. Obviously they don't recognize his greatness. So, he's going to prove how deserving he is. He attempts to infiltrate a Cuban exile group and fails. He tries to bait the exile group into an altercation, and ends up getting arrested himself. Then he has a debate on local radio with a person representing the exile group. This turns out badly when the moderator points out Oswald's earlier defection to Russia. This is all in addition to the constant job changes (he keeps getting fired) and inability to support his family.
So, things aren't working out so well in NOLA for such a deserving man. Obviously its everyone else's fault. So he moves to Texas. Buys guns. Tries to travel to Cuba (surely this is a Marxist utopia that will recognize how destined for greatness he is). Cuba doesn't give him a Visa....reasonable to assume that the Russians warned them about letting this nut-job into their country. He tries to kill ret Gen Walker, but fails. He can't support his family, so Marina and kids move in with the Paines in Irving, Oswald rents a room near the School Book Despository, where he's gotten another menial job. Having failed miserably at every undertaking, and blaming society for his failures and failing to recognize his greatness, he decides to attempt the greatest act of all...assassinating the President. Unfortunately, he succeeds. Blind luck that all the cards fell in his favor, but they did.
