I think Man in Black = Smokey

Its the Man in Black who wants to leave the island which would support the fact that Smokey is The Man in Black who is also Fake Locke. There is no evidence that Smokey wants to leave, so either we need a backstory about Smokey having the same story as the Man in Black, and they both share the want to leave, or we come to the conclusion that Man in Black = Smokey
