The narrator snaps and vows revenge on Fortunato due to Fortunato's insults and perceived disrespect towards him. Fortunato's insults, combined with the narrator's jealousy and wounded pride, eventually push him over the edge and drive him to seek vengeance.
The story does not say why Fortunato insulted Montresor. In fact, there is doubt that there ever were any insults at all. They might have simply been a product of Montresor's imagination
The hook is knowing that Montresor plans on exacting the perfect revenge on Fortunato and reading further to see if he actually does it. Montresor states in the opening that a wrong is not avenged unless the avenger is not caught and that the person who committed the offense must know he is now paying for that offense. The reader gets hooked into continuing into the story to see if Montresor will actually commit the perfect crime and how he will do it.
Fortunato is described as a powerful man who is respected and feared, making him perhaps, a bit of a bully. He's competitive and always wants to beat everyone, which may make him a bit narcissistic and insensitive to the needs of others. He is undoubtedly a prideful and careless individual. Yet, we only have Montresor's claims that Fortunato as a man who had caused him a thousand injuries to go by in terms of whether these transgressions were intentional or just part and parcel of a pretty clueless person. It doesn't require much of a stretch to imagine Fortunato as a man who doesn't weight his comments carefully before their utterance. As a result, he probably offends many, though not necessarily intentionally. Unfortunately, some, like Monstresor may have mistaken a naturally insensitive demeanor for blatant, intentional disrespect.
Fortunato treats Montresor with arrogance and condescension in the catacombs, showing no remorse for any wrongdoing that may have caused Montresor's wrath. He continues to insult Montresor and boasts about his knowledge of wine, unaware of Montresor's true plan for revenge.
I believe that Poe does not tell us the nature or describe any of the "thousand injuries" that the narrator suffered because he expects the reader to know what caused Montresor to seek revenge against Fortunato. Montresor claims "You, who so well know the nature of my soul,' as if he expects us, the readers, to knowledge the cause. Poe also wants the reader to wonder whether Montresor is sane or insane. Poe leaves open the possibility that the insults may be imagined so that the murder of Fortunato becomes more dramatic in that it was not necessary at all. This is similar to Poe's The Tell-tale Heart, in which the reader is left to wonder whether the narrator in that story also commits a murder for no real reason.
