Wishes, smoke, confinement to the island - it sounds analogous to the genie in a bottle. MIB is the genie, who wants out of his bottle, the island. He is recruiting people to help him to the end by offering to grant their wishes. He seems to be seductive in the way he promises things, with no strings attached or caveats. But be careful what you wish for.
In contrast, when Jacob offered to heal Dogen's son he made the consequences of accepting his offer very clear. Dogen would never see his son again.
I'm not very well versed in Genie mythology, and I wonder if this analogy can only be applied to MIB or if there is some similar role to that being played by Jacob in Genie mythology.
