We need to bear in mind, I think, that only a few days have passed since he shot Ben. He's the same person, it's just that he's been incapacitated for most of his time on screen since then. The person who was capable of killing Ben to prevent the future ever happening is the same one capable of betraying everything for a chance to see Nadia again. The knowledge that he has already died and that he is considered evil probably just helped him along the way.
My only minor gripe with that is that we don't know for sure that Nadia's death was a result of Jacob's influence. After all, if Jacob hadn't stopped Sayid, he would also have died with Nadia. If anything, one could perhaps fault Jacob in that he didn't stop Nadia from crossing the street - on the other hand she wasn't forced to continue walking, she could have just as easily stopped with Sayid when Jacob asked for directions. Her death was a matter of free will - she chose to continue crossing the street even though Sayid was talking with a man asking directions, she chose to stop in the middle of the street to tell Sayid she had found her glasses. And if the driver of the truck was truly sent by Widmore (we have only Ben's word on that, but we don't have any elements to prove that wrong), then the accident was, literally, waiting to happen.
I think MiB is making a huge deal of "Jacob robbing people of their free will" and "manipulating them"... but I'm not sure that's what is really going on. He seems to be much more manipulative, in a subtle fashion, by disparaging the actions of a dead man (who obviously can't argue with it or explain his part) to make himself look like he's a martyr and a savior.
