How Was Alex's Death Ben's Fault?



I was listening to the showdown between Ben and Widmore in Widmore's bedroom and Widmore claimed Alex's death was Ben's fault.

WIDMORE: Don't stand there, looking at me with those horrible eyes of yours and lay the blame for the death of that poor girl on me, when we both know very well I didn't murder her at all, Benjamin. You did.

How's that? One argument is Ben's disavowal of Alex led to Keamy killing her, but how would Widmore know about that given the death of everyone who witnessed that?

Here's my new argument. I think Ben taking Alex from Rousseau was his attempt to course correct. Ben had been pulling a Desmond thwarting Alex's death right and left for 16 years. And the universe finally caught up with him. Alex's death at age 16 is Ben's fault because she was supposed to die as an infant when Rousseau went nuts again. I further predict we'll see this during Rousseau's story in Season 5.
