Would you like to save the world?

Dharma uses it as advertising.

Mikhail was recruited by “a magnificent man” after seeing the ad.

Pushing the button was to save the world.

Good guys/bad guys. Can’t get the losties all back? “Then God help us all.” Seems a theme as obvious as black and white.

So – is this a pile of steaming *expletive delete* … or is there something else beyond what we know that could go wrong/be very bad/end the world?
