I think he was pretending to be Christian and was messing with Locke that whole time. And guess who else got manipulated by some dead person...Ben by his supposed daughter's spirit...right after the smoke monster. Soooo if you could follow all that, I think Nameless is the smoke monster. In other words, dead characters like Christian have never really come back to life. It was Nameless pretending to be them the whole time. Which makes sense if you think back. Like Mr Echo was right! It wasn't his brother! So the smoke monster/Nameless killed him because he figured it out.
