Who’s side is Widmore on?

Written 10th March

At first i thought the “people” Jacob said where coming to the island where going to help out jacob and company. And since Widmore is an Other it would make sence he would be on jacobs side. But then again Ben said its was jacobs choice for Widdy to leave the island. Now MIB seems to have a good team already and it would be a good match up between the two sides if Widdy teams up with Ben and Jack. But since Widmore wants to exploit the island it seems him and MIB have similar interests. It was a very suspencfull ending! Go Lost. please help
