Hi! I am currently reading the story " The Cask of Amontillado", Well i just finished it. But From the excerpt that you have given it seems like it is describing conflict. This can be supported, when he says " The thousand injuries of Fortunato I had bourne as best i could, but when he entured upon insult I vowed revenge". This is stating the beginig on conflict. Fortunato started the conflict by insulting him, so he had "vowed revenge", which brings the conflict to continue. - I hope this has help! if there is anything else you need help with i will be more than happy to help.
