I think that “where the worm never dies” pretty much settles it.
What is “the worm”, and what does “never dies” mean? How one answers those questions will give you a clue regarding their perspective on “hell”.
i.e. it only settles it, depending on one’s interpretation and understanding of the root source and culture from which the phrase comes.
I do think the context is perfectly clear, as well as it being read in conjunction with other scripture on the subject.
