CHARACTER MOTIVATION IN
"THE MONKEY'S
PAW"

• SERGEANT-MAJOR MORRIS. Morris
  apparently loves being the center of attention and to tell stories about his travels in the
  service. He also likes to drink, and he must have been lonely to come to such an out-of-the-way
  place on such a bad night. He must have brought the terrible paw in order to entertain his
  friends with another strange tale.


• MR. WHITE. The father likes to
  take the occasional gamble, as he shows during his chess match with Herbert. Retired, simple and
  otherwise conservative, he allows himself to be manipulated by the others in regards to the paw.
  First he saves it from the fire, and then he pays Morris for it. Then, when he can think of
  nothing greater than paying off his mortgage, his first wish is for a mere 200 pounds. He does
  not have the courage to destroy the paw after the first wish, and he only compounds the terror by
  completing the wish cycle of the paw.


• HERBERT. Young and
  impetuous, Herbert jokes about the paw and its powers, but its impact on Herbert is no laughing
  matter. The joy of the Whites' life, Herbert is taken from them with the first wish of the
  paw.


• MRS. WHITE. A simple, aging housewife, she dotes on her
  single son, who still lives at home, and her grief at his death prompts her to suggest the
  chilling second wish. Like the second wish itself, Mrs. White doesn't think things through, and
  she clearly has no idea what terrors can come with the
  paw.
