So would you say that Jacob would feel vindicated about his freewill theory because most of the losties have redeemed themselves on the island, prooving free will can be good. Many of the losties killed someone prior to the island but also killed on the island to protect themselves. Proof that everyone has good and bad in them and that under the right circumstances will sacrifice for their friends.

Maybe blackshirt (as you call him) has been causing the rifts and chaos among all the inhabitants in order to eliminate them all from the island. This coupled with the absence of children would eventually lead to an extinction.

However, Widmore, Ben and Charlotte wanted desperately to get back to island (and later the Oceanic6). Ben, Charlotte and the Oceanic6 succeed, but not Widmore. How will blackshirt prevent everyone who left at some point, from ever finding the island again. Also, do you think Jacob caused all the arrivals? (BlackRock, hot air baloon, the DI, Danielle and crew, Desmond's sailboat, Oceanic 815, the freighter and flight 316.)

I wonder why Eloise Hawking never tried to help Widmore return to the island via the Lighthouse. We saw them discuss their son Daniel in season five. It is was so easy for flight 316, why didn't Widmore join them?
