What phrase used by the narrator is an example of hyperbole in the cask of amontillado? does it make you feel more or less sympathetic?

"The thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge." Obviously, Fortunato hasn't harmed Montresor a full 1,000 times. the line makes me less sympathetic because I can't imagine Fortunato has done anything so terrible as to deserve a brutal killing.
