Ben has obviously done a lot of bad things, but he's always tried to tell us that he is one of the good guys. For some reason, I want to believe him.
Charles Widmore has been a jerk to Desmond, killed another other back in 1954 and most importantly sent a team of mercenaries to the island with guns and C4. Both seem like bad guys.
The latest episode of LOST makes me want to change my mind to "Ben really is the bad guy, and Widmore really is the good guy." I guess we shall have to wait and see.
What do you think?
