It is also Mr. White who retrieves the monkey's paw when Sergeant-Major Morris tosses it into the fireplace and Mr. White who insists on keeping it against Morris's advice. Mr. White pays Morris a small sum of money for it, which makes him the legal owner and the only person in the family who can make a wish. All three wishes are his, although his second wish, to have his son Herbert return alive, is made on behalf of his wife and only at her insistence. There are only two characters who can be considered major. They are Mr. and Mrs. White. Sergeant-Major Morris is only present in the first scene, and his sole purpose is to introduce the monkey's paw. Herbert dies early in the story.
In the short story, "The Monkey's Paw", Mr. White is the main character which makes him a major character. Major characters are important in the story and move the action forward. Mr. White is the person who sets the chain of events into motion including making the first wish as well as the following two wishes. In my opinion, he is also a dynamic character which means that he changes in the story in contrast to a static character who doesn't change. Mr. White changes from the conservative man who plays chess with his son, is retired and content to be so, and doesn't take risks very often. In this story, he decides to go ahead with the wishes against his better judgment, isn't careful at all with the phrasing of his first or second wish, and makes the third wish in desperation. He, of all the characters, loses the most because he not only loses his son, he loses his wife also which means he is now alone with no family in his retirement.
