I want to smell dark matter
The island healed Locke after the crash, and every since then he's been all "this island is a wonderful place of fun and oranges!" and doing whatever the island asks for him. But "fixing people" seems to just be something the island does, a side effect of its unique properties. It doesn't seem like an act of kindness. So what if the island itself, its "spirit" (Jacbo? Smoke Monster?) is actually EVIL? It killed Eko (granted he'd done some bad things but why was it up to the island to judge him?) apparently ordered Locke to kill Naomi (who, as far as we know, was good) and probably did other bad stuff too. Maybe Locke will eventually realise this and stab the island's heart with his hunting knife or something?
