Convincing the MIB that humanity isn't evil is clearly one of his top priorities. He literally risks everything to prove it every time he brings others to the island because only these outside elements have the power to kill him. Instead of doing the only safe thing, he insists on repeatedly risking his life to prove a point.
* Jacob and MIB are two sides of the same coin (balanced) that are both necessary to prevent whatever is being contained in place.
* MIB, at least once, does the bidding of Ben which implies some control/function of MIB beyond fighting against Jacob.
* Jacob says "they're coming" to MIB as if it is significant to both of them. Why warn him unless to make a point that his services are still needed/that their conflict is smaller than some larger threat?
* The only person who's intentions are not known is Widmore and the great battle will be between a finally united MIB/Jacob team (led by the Jacob's replacement) and Widmore's forces.
