"Lost" & Death: An Interesting Theory

I completely agree with the theory - it does seem coincidental that the ones who resolve their "sins" are the ones whose lives are taken away by The Island.
Now, I'm worried that if everyone resolves their "sins," there will be no one left alive!

This is a very sensible theory, but I wouldn't necessarily agree with its depth. It's logical, isn't it, that a show where the writers aim to kill characters off, would choose to get rid of the characters that appear to have run their course and don't have anywhere left to go within the narrative of the series, instead of keeping characters they don't need or killing characters that still have stories to tell? (Or that they were arrested for drunk driving.)

I mean, this isn't necessarily true, since Sawyer and Michael are still alive after (respectively) ridding himself of the man who ruined his life and building a healthy relationship with his son, which might mean that their central life conflicts have been resolved, but they might still have a role to play in important future storylines.

Then again, what would have been Charlie's central life conflict? Kicking his drug habit? Renewing his faith? Maybe he just needed to finally become the adult he would have been before he became famous, and coming to terms with his impending death was what actually caused him to die.

A fascinating theory, if somewhat flawed. What to make of the couple that is buried alive? No resolution there. Were their deaths just gratutious? And if the island is some kind of purgatory, what role does The Others play?

A more interesting question may be what is good and evil? Are The Others really evil or just trying to protect their island from invaders? All the Oceanic survivors (and some of The Others, the ones we know about) are deeply flawed, but we have embraced many, if not all, of them, and their flaws, even those who have committed murder. I think the moral landscape of this show is totally fascinating.

Finally whatever happened to the older married couple (names escape me at the moment) who were reunited in the second season. They have totally disappeared with no explanation. While I love the show, I find this a major flaw and am disappointed that some explanation wasn't presented.
