Sayid's Protection

Sayid is back to torture and assination in the latest flash forward in Lost season 3, but who is he protecting?  It can't be the other Oceanic 6 because they seem to be doing fine.  I think this little play on who Sayid is protecting leads to the fact that many of the survivors decided to stay and live on the island.

So is the oceanic six the really the only survivors of flight 815 - or is every other survivor still living in the compound on the island?  Think about it.
