If the second hell was indeed about the underworld magistrates intervening during life, then the third hell appropriately presents "Ghost gate pass" with various sinners finally being led to their fated retribution in hell. (Most sets of hell scrolls imply no such narrative link between scrolls, and so we can only speculate here about any intended storyline.)
In terms of torture, most space is here given to decapitation. From the late sixth to the early twentieth century, the "Five punishements" in the law codes consisted of various degrees of flogging, pernal servitude, exile and death by either strangulation or decapitation. Decapitation was the worst because it did not preserve the corpse as whole. Yet these punishements are not common in the hell scrolls. (Flogging with the bastindo can be seen in C05 and J10; decaptiation is present here on A03.) They are perhaps not sufficiently gory to be shockingly memorable and to thereby magnify the importance of practicing the particular behaviors associated with each torture.
When discussing how the contemporaneous legal code relates to purgatory, Brook, Bourgon and Blue in their Death by a thousand cuts argue against simply projecting the bureaucracy of the living world into the world of the dead because there is indeed a transformation of the former when seeing the latter:
Allowing that connection [between the real and the imagined] commits one to accepting, at least provisionally, that at some level the imaginary relies on the real to be intelligible, and that the worst the imagination can envision reflects what people most feared. For heuristic purposes, we posit that the torments that filled purgatory related, at least indirectly, to real-world practices, if not real-world experiences. Yet we do not want to allow ourselves to glide too far on this assumption, given that the imagination is capable of giving form to and investing meaning in things that could never happen in the here and now. The next world is never a pure reflection of this one; we have to bear in mind that their relationship is much more complicated.
Hence when one moves from this world through the "Ghost gate passs" into hell beyond it, it is not a simple move between like worlds. Decapitations will give way to drowning in blood ponds, boiling in oil caldrons and being pounded into meat jelly within giant mortars, over and over again.
