The Cask of Amontillado

I really liked how this grabbed my attention right away. "The thousand injuries of Furtunato I had borne as I best could, but when he ventured upon insult I vowed revenge." I thought this had to be good. I thought that Montresor had to be plotting this revenge for a while. He did wait until the right moment, when Fortunato was already drunk and wanting that Armontillado. The way he used his "sincerity" to lure him deeper into the tunnel. Having everything in place, waiting for Fortunato to come and ready to box him in. Montresor must have been a little bit crazy to be able to put up that wall the whole time he can hear Armontillado in there with his screams, laughs and cries. Yet, he is simply getting revenge for, well, for what? An insult? If I was a jury member at Montresor's trial, I don't think I would believe an insanity plea. He planed this out to a T and only 50 years later does it come out of his mouth. He doesn't even seem remorseful about it. His tone almost seems like he is trying to warn someone else to not cross him.
