The words that better describe the writer's tone towards the narrator and the story are sympathetic and pessimistic.
The narrator tells the love story between Annabel Lee and himself.
When he narrates that the angels envied their love and took Annabel away from him, he means she was compromised in marrying a rich parent, and that was the same as death.
In the fourth strophe, he says the angels were sad for her death, but were yet more envy of their love.
In the fifth strophe, the narrator declares that nothing could be bigger than their love, and not even the angels sent from heaven could separate two souls that love one another.
He narrates the way Annabel Lee was taken away from him, first being forced to get married against her will, and then from death, in a pessimistic way but even so, he feels sympathetic about the love they have, because it is greater than life or death, and nothing could separate them.
It is a romantic poem, in which the words vibrate in an impressive way, and it brings to the poem a sonority and beauty that is a characteristic of Edgar Allan Poe.
