He's neutral. We're not entirely sure what role he plays, best I can gather he's a "guardian" of the Empty, of sorts. Any demons or angels that die stay asleep in the Empty, but when Castiel is awoken, that woke him up too and he wanted to get back to sleep. He did beat up Castiel which gives him something of an antagonist position, but in the end Castiel got him to revive him so he could go back to sleep.
