Because of this, there are not many of these types of 'demons/angels' in Heaven or Hell, as they never go to purgatory, and as such, are never found and transformed into demons by the Torture demons. Often times, the ones that have died in the past, are usually snatched up by Purifier Angels and created into Angels instead. Angels lust after great soul energy/strength and the Nasgu'e are full of magical energy due to their prolonged life status. Their souls just get stronger with age in life.
