Question

do you interpret the poem's final stanza is an expression of powerlessness, or as a threat? defend your opinion.

Answer 1

I don't believe that he means it as a threat he really does mean it as an idolization of powerlessness due to the fact that throughout the poem he's using language that you could only expect from someone in a hopeless or powerless situation  an de to the fact that the tone is slow and you could say placed in a logical way as to show a sense of powerlessness (hope this helps)
