the difference between hell and purgatory is that purgatory has an end

"We haue also with vs in hell a ladder, reaching of an exceeding height, as though it would touch the heauens, on which the damned ascend to seeke the blessing of God; but through their infidelitie, when they are at the very highest degree, they fall downe againe into their former miseries,"
Mephistophilis to Faust the english faustbook'

The kingdoms of hell are manifold,
Lacus mortis, the lake of death
that sterile mirror
with a namesake on the face of the barren moon
Gehenna, the smouldering trashheap of Jerusalem,

there are the kingdoms of lost things,
the sea of shipwrecks,
the tumbled confusionof the world unbuilt,
the house of broken promises

kings once carved in the walls of their tombs
"let me not walk with my head downward
eating feces in the land of the dead"
raised altars that they might not thirst in that place

and what will you do, when you come?
oathbreaker, devourer of hearts,
prideful liar and despoiler of innocence?
will you find your house of panderers,
the indolent aids in your self devouring sideshow,
the flattering audience to your atrocities?
will you drag the hollow idol of your pride
to that house, too?

there is a city, on the shore of a lake,
surrounded by marsh
if there is enough liquor
perhaps you will not notice
where you are
