How do you get that MiB wasn't evil? He was a powerful liar and manipulator, even as a child, and stabbed his foster mother to death, from behind, no less. You get a more nuanced look at him, true, but nothing I saw changed my view to good, or even neutral. He's a bad, bad, boy.
As for Jacob, the island may give him dispensation to go abroad and "recruit" new candidates.
It would have been more annoying than not naming MiB if they had beeped it out every time it was said, like Kiddo in Kill Bill.
