I agree with Wednighter - Locke is not a team player, he's a maverick with his own agenda. In season one (which I have been rewatching) he was never really around camp for that long. He was always gone. He show up whenever they needed a search party or hunting party or something like that, but he didn't really build a shelter, or chop fire wood, or salvage pieces of the plane (except for his box o' knives) etc...
Remember when Boone hurt his head and Locke smeared that mind altering goop on his head. That was weird.
