I think it’s “character vs. nature because his hunger is driving him to take risks” as first of all: he’s not afraid (cancels out the second one), he’s hungry (“my hunger burned in me”), he knew that god’s food can be death (but he’s still going to search the food of the god’s - taking risks bc he’s hungry), he’s not facing demons (cancels out third one), he’s not breaking ‘laws’ because it’s not legally enforced that you can’t steal food from god. Therefore, the last one would make the most sense to me.
