Dudes!!! Ben Linus has got to be an ENFJ gone very very wrong.
He's the classic manipulator who stores tons of information about each individual and how they connect with each other, and uses that info to orchestrate everything without seeming like the traditional idea of a leader (ie Jack).
ENFJs desire harmony. In the scenario on Lost, harmony is why he's so hellbent on "protecting" the island. He has no qualms about using his powers for what he thinks is the greater good.
Allow me to quote from the ENFJs: Not Manipulative thread:
"ENFJs' skills lie with people and feelings, and they know how to manipulate either or both, to their own aims. They know how to gloss over the truth and present it in an altered form that appears to be correct to those who are not keen enough to pick up on it. They are naturally dramatic and speak with conviction; they'll get under your skin to provoke an emotional reaction. People buy what they sell -- hook, line, and sinker. Those that suspect something is going on can't point it out logically so their claims look to have little veracity. All the facts and logical explanations in the world won't matter. Even the "enemy" may begin to believe them." -- Lauren Ashley
Yup. Totally Ben Linus.
