Just discovered a thinly veiled reference to Mother Teresa in the Requiem
comic. In part 2 ("Danse Macabre") there is a zombie/ghoul, which are hypocrites in hell according to the story, called Mother Terror.
During her life she ruled over hospitals which didn't give the proper care to it's patients, causing them to die a long and painful death. She also received millions of government grants which have all dissipated. Her reaction to these allegations: "painful suffering brings people closer to god" (Which was also something that Mother Teresa was supposed to have said).
Also part five has a few hellboy lookalike cameos.
And I still think the story is kinda weak. But the setting is nice :).
