without an otherworldly hell, a Nazi this-worldly hell?

has any serious, independent, scholarly "philosophical" thinker -- a philodicer, as it were -- considered the actual social and "intellectual" history of a loss of the idea, imaginative belief, and earthly fear of Hell, as well as a real living sense of embodied conscience (Gewissen), and the influence of this in the rise (and brutal realization) of "Nazis(m)" and their fellow travelers, whether willing or not?

(and this is, terribly, just one of many such (in)human histories to trace in the 20th century.)
