It's possible that he was human. It also seems to be possible that he was turned Undead by an outside force if you take the Sewer Chamber Key's decription into account.

" In any community, a few bad apples are sure to exhibit insatiable greed. If they were turned Undead, and banished to the Depths, would they reconsider their ways?"

And I'm rather certain that rebelling against the gods would classify him as a "bad apple" in the gods' eyes. Provided that theory is accurate, of course.
