The term god is hard to define in TES. However, it's still pretty easy to say that Alduin is a god. Alduin is a shard a Aka, the original time spirit. The LDB exists to stop Alduin from enslaving mortals because this is not Alduin's role in the Aurbis. He is the World-Eater and the end of time, not a slaver or tyrant. Alduin's soul is not absorbed by the LDB implying that he may not be dead. He could have gone back into the oversoul of Aka. Never anywhere does it ever say "kill" Alduin, only "defeat."

M'aiq is correct. Alduin is not Akatosh, but they are both shards of Aka.
