Madam P, I am in agreement. I have been an advocate that MiB is essentially the good guy (and Widmore

but this last episode has me thinking Im wrong. MiB (and Widmore) seem to have taken a step into the dark side, MiB seems very sinister right about now.
I cant quite put my finger on it but I get a very uneasy feeling towards MiB, the only saving grace is that maybe his beleif is that if he is sucessful all the people he killed will be alive and well in the LAX timeline - he killed them for a greater good and they all live happily ever after in his ideal world.
Widmore, who I have always thought was essentially the good guy seems to be doing his damnedest to be a real 'dick' as someone quite aptly put it.
But it puzzles me, as Jacob also seems to have done some nasty stuff too - all 3 cant be the bad guy can they?
