In "depression, the secret we share", how does including emily dickinson’s poem at the beginning of the speech support solomon’s claims about depression?

the answer is a)   a sentence of death costs the state "almost three times as much as a sentence of life in prison" (delon 147)

in the line from the end of the story "the cask of the amontillado," by edgar allan poe, the narrator has put the last stone on the wall, thus sentencing fortunato to death. just like that montresor associates his feeling of sickness to the humidity of the catacombs, and seems to be glad he has taken revenge on fortunato. however, montresor's last words are "in pace requiescat," which mean "may he rest in peace." as a result, it can be inferred that he hides or does not want to assume his guilt or remorse for killing fortunato in such a horrible way.
