Ok, so after last nights episode "he's our you" I have to say that it is pretty clear that what the survivors are doing now will be the cause of everything we already know happened like the purge and "Incident" whatever that may be.
Just think about this one thing.
Dharma and the hostiles have a truce and are seemingly living together peacefully.
Sayid is given a truth serum and tells them they are all going to die in the purge. Remember, they believe him to be a hostile and don't believe when he says he is from the future, they just think they gave him too much of the serum.
So combine Sayid telling them that they were all going to die in the purge with him killing or attempting to kill (There is no way young Ben is dead) a little boy and I think it is safe to say you have the spark that will ignite the flame of war between Dharma and the hostiles and lead to the incident and eventually the purge.
