Apologies if that's a bit mushy, but from the practical assignment of point values for "fatalism," I have found that about half the points for this significant category have come from the sense of danger, peril, suspense that oscillates through the film, and half from the definition provided earlier. So, looking at "fatalism" for DELUSION, I'd likely give 5 out of 10 for the portion I sense you are measuring (as the film is only intermittently referencing the association between moral emptiness and the space that the characters inhabit), and an additional 6 out of 10 for the level of danger and peril that is created in the overall experience of the film as it plays out. That would bring the combined value of the two aspects that I think need to be covered by the term "fatalism" to 11 out of 20.
Some of the need for this approach to the "fatalism" element came from critiques of the earlier method where the point value was higher (25) and the values assigned were too dependent on hard-boiled plot features. Films with flashbacks were scoring way too high relative to other noirs because that narrative structure does amplify the sense of "fatalism" and without a way to minimize the difference in "feel" created by such a plot/narrative device the method was creating a distorted set of measures.
The only other area where I might adjust the point value is in "alienated protagonist," as I always felt that Meltzer's character was clearly pushed into what he did by a fairly sizable amount of disillusionment. I think I'd up that to 6/10 myself.
