Finally, some answers--and, obviously, more questions that go with it. So Oceanic 815 crashed on the Island because the passengers inside, or at least some of them, were pegged by Jacob, at one point in their lives, to be his successor. Surely the same also happened with Black Rock, and Danielle's gang, and maybe the folks at the DHARMA Initiative, too. Along the way, names were crossed out, probably because they weren't sympathetic towards the cause. Now, with Jacob dead, Locke is looking for a replacement--a substitute--and... isn't there something wrong with it?
I mean, the Man in Black and Jacob have coexisted on the Island for what seems like forever, and yet they never really got along. MIB, in fact, just wanted to get rid of Jacob, exploiting his loophole to fulfill the deed. Now he's looking for someone to replace the very person he killed? To what, regain the balance in the world? Is he just looking for someone else to kill? He's getting a kick out of it.
Of course, that isn't the only option. I'll whip out my own list.He is eliminating the competition.
The only thing Locke (let's call him that to make things easier) can do to fully gain control of the Island is to manipulate all of Jacob's candidates not to take the job. He's doing a pretty good job, since he's convinced Sawyer to just go home and forget anything ever happened.
But it isn't really working. Remember the kid Locke saw so many times? Some say it's Jacob, since he knew about the rules. Some say it's Aaron. In the end, Locke's plans will fail because even if he eliminates the candidates, the original is still around to keep the balance.He is really Jacob, looking for a replacement so he can go home.
This will sound ridiculous, but stick with me on this one. Basic premise: the person we know as the Man in Black is actually Jacob. He still did the actual off-Island touching, but he took on a different case with Ben: so he can push his agenda, he killed the actual Man in Black, and is now looking for a suitable replacement so he can break free. (If he is having fun on the Island, why would he want to go home?) And by suitable replacement, I mean someone who is committed to the cause.
Of course, there are many holes here. For one, how the heck would MIB look like Jacob? Are they twins? I know, ridiculous idea. But I'm suggesting that in this scenario, MIB actually has the upper hand at the moment--think about it--and Jacob has to do things a different way to regain control, somehow.He is just looking for a more suitable Jacob.
Sticking with the good vs. evil theory, let's say there are defined roles for both MIB and Jacob. And then there are the rules, which surely isn't just "you can't kill one another". While they may not get along well, they are both sworn to check each other in order to keep everything working. So Locke had Ben kill Jacob. Is it because he just hates him? Or is it because he totally disagrees with the way he works--manipulating people, having control over their lives until they end up on the Island and take over his duty? For someone who's supposedly on the side of good, that is evil.
In that case, you can say that MIB is still evil, but is just doing his duty. As for the bit about going home, maybe he's just tired of things (especially with Jacob doing such nefarious deeds) and just wants to take a break. Think about it: if MIB wants to go home, who takes over his place?
For some reason this reminds me of Desmond's time at the Swan: him killing Kelvin, and later, looking for the very people to replace him. Parallel situation, perhaps?
Regardless of what the scenario is, I will say that all this is because the balance was upset way before the Oceanic 815 crash. And, in the end, a bigger Incident will happen, where everything that went wrong because of the imbalance will be erased. The plane lands safely. Hurley is lucky. Locke accepts his fate. Kate is still on the run. And Ben would be complaining about people who don't clean the coffeemaker rather than Widmore changing the rules.
