LOL- sure if that suits your taste
but it's a flaw of logic to claim on one hand that we don't know if Witmore's good or bad and say on the other that Ben is evil. Sayid, Kate, Sawyer, even Hurley- all have lied for their own interests.. FFs show they will so in the future. They even killed or lead to the death of a bunch of people (though unintentionally, in the case of Hurley) ...so? The whole show's about twists showing how such judgments prove to be rather limited every time the viewer takes comfort in them.
