Ok, first I want to say that this is a SPOILER.

Remember in the promo for the Life and Death of Jeremy Bentham, Widmore tells Locke that the island needs him? Well, does that mean that Widmore is a good guy or is he just being manipulative? I think that he might be good, only because that would be an interesting twist for Lost to take. Or maybe he won't be a good guy, just like working with the others for the sake of the island. What do you think?
