It may come as a surprise, but Hell is dominated by a bureaucracy; as chaotic as the underworld may be, people have identified a hierarchy and distributed specific jobs to each demon. As in the case of angels, the hierarchy of demons includes different demon ranks, attributes, and domains to rule over. Demonologists used various characteristics to organize demons into a table that illustrated their standing in Hell, their special powers, and their pet sins.
Included in the hierarchy are demons popularized by the Bible and those brought into the mainstream by books and movies. Each one serves a specific purpose, and many are the twisted mirror image of an angel in Heaven. Different demonology scholars and religions categorize the demons in different orders, but their motives and vices remain much the same.
