1.) The fact that Widmore sent Daniel and Charlotte to turn off the Tempest, does that mean that Widmore is really a "good guy"?

2.) The fact that the countdown was already running by the time Juliet arrived, does that mean that Ben set it to go off? Or did Daniel and Charlotte have to set if off in order to disable it?

3.) Do you guys think that the gas was being developed on the island in order to use it off the island? Like in the Terminator movies how Sarah Connor has been to the future and she goes on an assasination spree to kill all the people who are part of the movement to make computers self-aware. Maybe the gas was meant for the people Sayid was going after for Ben?
