What point of view is "the black cat" written from? what is the effect of writing in this point of view?

The story is presented as a first-person narrative using an unreliable narrator, since in a first sentence he says he does not expect or solicit belief.

The narrator of this novel is a few words a sociopath, who is a person who does not respect the laws or social norms, who ignores the right that other people have, has a violent and aggressive emotional behavior and does not feel any kind of remorse or guilt for their actions.

The protagonist used to be a docile and kind man, he had a great taste for animals, but his character changes, not because he is an alcoholic, rather it was an impulse that leads him to be an irritable and violent person, capable of make tremendous atrocities without remorse, and that triggers the terrible scenes that are told in the story. He mistreated his wife and animals, except the cat that had a huge fear

Point of View: he gives his own point of view, he does not think he is crazy, he knows that he will die the next day, and his end is only to express his case, he also adds the series of consequences that he is going through, as he says he feels "terrified, tortured and destroyed"

i would like to compare these two interpretations of the crucible : 1) eric christ's interretation and wade bradford's interpretation. the main differences between there interretaions is that in the first one you can notice direct link to joseph mccarthy whereas the second one represents how the town is filled with hysteria.the second interpretation shows that author believes that the story   about puritan town in salem is based on actual events while the first example shows the sencible reference to sort of bias.
