So Ben, you think the impregnating problem is because of in-breeding. Inbreeding can cause retardation, but not death of every single female and offspring.
But i do believe everything is a mindgame, Integrated. I mean look at it this way, Ben was way to quick to send Goodwyn and Ethan off to the plane wrecks, he had an idea, what, seconds after the crash. He knew it was coming or he dealt with the situation before(or it's coming back around). Almost everything Ben says is almost the exact opposite of it's literal translation. I think the Others are basically going about it in the same way, and you have to glean bits of truth from their stories.
