How about this? Because I really agree with Mango that Richard probably did use the island to resuscitate Ben. Ben was not dead at that point so he was really healed more than resurrected.
But nevertheless, I'm really beginning to think that the island's healing/life giving properties are like the electromagnetic properties - completely neutral and available to whomever taps into them. The difference with Locke is that he has staked everything on the island and the island has received him so completely he came back from the dead. Locke is closer to the island, if you will, more so than any one ever. Therefore Locke's life and quality of life is improved more substantially than any one ever before. He has out-Benned Ben.
Yes!!
