While the need for revenge is the immediate impetus for Minnie Wright's strangling of her husband John, her isolation is the ultimate causes of her unhappiness in their marriage. As Mrs. Peters and Mrs. Hale note, John Wright was a hard man and did not provide the companionship needed, while Mrs. Hale blames herself for never having visited to offer Mrs. Wright a respite from her loneliness. Both women suspect that the canary had been a substitute for Mrs. Wright's lack of children and other friends, and Mrs. Peters' account of her solitude while homesteading in Dakota suggests that loneliness is an important element of the female and human condition. Mrs. Hale realizes that woman have all experienced loneliness in part because they do not realize their commonality and thus have not learned to unify and support each other. In the end, loneliness connects the women and brings them closer to each other.
