Ben's most likely not Dead.
And the more I think about it, I'm ticked. Sayid is a trained killer. He took 1 shot at Ben from 20 or 30 feet away in the dark with 1 hand. Every other killing they showed Sayid do he took multiple shots into his victim or at least ensured they were dead. No Exit wound. A trained killer would be more efficient than that.
Not sure where the show is going, but I don't think we are seeing 1 path where history can't be altered. Meaning if we fastforward all the way to 2004 from 1977, you won't see the Losties back on flight 815 and crashing on the island.
I think you have to be dealing with a parralel universe of some sort. One that is functioning a layer below the one we know. The one that is in 2007 now with Jin and Ben on the other island.
Still doesn't explain how Locke is walking around. It would have made more sense if he somehow flashed to a day before his hanging. Him just coming back to life after a crash and not a flash is very odd. ANd even then, I would think death is permanent regardless of when it happens.
