Maybe I have it all backwards about Lost. Maybe Jacob is actually the bad guy and Smokey is the good one. At the very least, Lost is going to make is wonder about who is really good and bad. A twist at the end, where Jacob turns out to be the villain would be quite a shocker.
Here’s the case for Smokey being good and Jacob being bad… Perhaps the trap that Smokey says he is in is being condemned to a world where the same mistakes are committed. In the parallel world we can see what it would look like if everyone got out of that trap by never coming to the Island. Kate would stop running. Locke would accept his disability. Jack would resolve his daddy issues.
Smokey wants to release everyone from the traps of their mistakes and let them move on. Jacob tricks people so that they never learn from their mistakes and stay ont he Island. Jacob gives Sawyer the pen so that he writes his pledge to seek vengeance. Jacob enables Kate to shoplift, so that she never learns to live within the law. Jacob heals Locke but perhaps in a way that he never accepts his disability.
Smokey is an advocate of free will and choice. Jacob seems to be manipulating everyone so that they do what he needs them to do.
Yes, Smokey has killed people, but Jacob may have killed many more. If the purge was done by Jacob order(and it seems to have been, given Richard’s loyalty to Jacob and involvement in the purge), then Jacob is a mass murderer. Jacob’s people also tortured Claire and Sayid. That doesn’t seem very nice.
Jacob may well be the good guy, but I wouldn’t be surprised if Lost flips on this issue.
