The main theme of the poem is one of undying devotion.The narrator experiences a perverse conflict between desire to forget and desire to remember. He seems to get some pleasure from focusing on loss. The narrator assumes that the word "Nevermore" is the raven's "only stock and store", and, yet, he continues to ask it questions, knowing what the answer will be. His questions, then, are purposely self-deprecating and further incite his feelings of loss.
Poe leaves it unclear if the raven actually knows what it is saying or if it really intends to cause a reaction in the poem's narrator.The narrator begins as weak and weary, becomes regretful and grief-stricken, before passing into a frenzy and, finally, madness.
