What does the speaker's choice of words such as, vowed, settled, avenged, and impunity show about his emotional state

This question refers to the short story "The Cask of Amontillado", by Edgar Allan Poe. More specifically, it refers to the first paragraph, where the mentioned words can be found:

THE thousand injuries of Fortunato I had borne as I best could, but when he ventured upon insult I vowed revenge. You, who so well know the nature of my soul, will not suppose, however, that gave utterance to a threat. At length I would be avenged; this was a point definitely, settled --but the very definitiveness with which it was resolved precluded the idea of risk. I must not only punish but punish with impunity. A wrong is unredressed when retribution overtakes its redresser. It is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.

Answer and Explanation:

The speaker's word choice reveals a lot about his emotional state. He is clearly angry for having been offended by Fortunato, even though he never reveals what the offense was. He has a vengeful feeling toward his "friend", and he is also clearly determined to not only carry out his revenge, but to also remain unpunished. We can also tell that, in spite of his anger, he is able to remain cold, speaking of his murderous decision in tranquil yet decisive tone.

if this isnt a true or false than they have equal amount of importants

        its hard for some people to get along and that’s the case for douglass and canot. most of the time when people do not agree with each other its because they have different presperctives, and that is the case here.

captain canot was never a slave so but he was a slaver and a slave ship captain and just like the slave master's he tought it was it was totally normal, he used captain conot is a cruel man who enjoys whipping slaves but never   got whipped he saw it has a destiny for the slave to be a slave and the slaver to be a slaver   but douglass has suffered whoppings cut   even for no reason sometimes. douglass believed that slavery was not natural to black people, they need to study and learn how to read and write. he knew they have rights.

it was really not the captain’s fault he was just brainwashed by the system and when your brainwashed by the system its hard not to be brainwashed. but the reason douglass wants this is because he has suffered he knows how it feels and will do anything to stop that.
