As for Locke being a better leader than Jack, no way, too emotional. That thai lady was right, jack is a leader of men and the Others know this, that's why they have manipulated him from day one, even dragging him into the jungle so they could see him run to the crash and start saving people, IMHO. but the games really began this season, they never wanted Sawyer or Kate, they wanted Jack, and that's it.

But this is a Locke thread, sorry to go off course. We really can't say why Locke is doing the things he is doing, but he is being guided. He may have saved everyone, and perhaps his gullibility will be an asset after all, esp if the 'fate' that's running the island is using him for good.
