What is it that the speaker hopes the raven will do by the end of the poem "the raven"?

I think the answer you are searching for is:

"On the fast track to madness due to the loss of his lover Lenore, the speaker in Edgar Allan Poe's poem "The Raven" would like nothing more than for the raven to give him good news about her return. When he asks the bird if he and Lenore will be reunited in Heaven, it accordingly responds "Nevermore!"

Hope this helps!!

both are bitter over their mistake
