They all died in the original crash and have been claimed by Wolv_256

I don't think this will be true, but it's something to think about.

If the two main Egyptian Gods (c'mon, they've made that obvious by now) Jacob and the MIB can claim and bring people back to life (like with whatever happened to Sayid), but they are somehow different (what they call the sickness), what if they all died in the original crash and therefore all have the sickness. Maybe some of them died and others didn't, hence Jacob's List. Maybe only the people on Jacob's list truely survived the crash, or vice-versa.

Maybe the others are enemies of or at least monitoring the Losties because they are essentially undead? Maybe the Others are the good guys because the undead Losties are the bad guys? Maybe Damon and Carlton's jokes about the last season being the "zombie season" wasn't a joke, but a clue all along?

I know, it's not that, but it's something to think about.
