I have been thinking this for some time now and this post helps with it.
Does Ben know something about being " the leader ". I have this feeling that Ben of course lies constantly and manipulates everyone for his own good. Could Ben have known Locke would die and placed Locke in his position as leader knowing that death was to follow?
I'm not sure how to explain it all but it seems that Ben may have been killed off and to escape this threat and the island being fond he moves it.
Thus Locke being killed while off the island from learning the OTHERS secrets.
Somewhere in there is a point?
