Everybody contributes to the world somehow and everybody is it's important part. The same happens in fiction. All the characters that are created by an author carry their own  purpose.Let's try to analize main personages from the "Monke's Paw". I'd like to start with the most mysterious and enigmatic character -  Sargeant-Major Morris. He is an old soldier who visits the Whites and tells them about his raveller experience. He is that man who introduces the monkey's paw at first to the family and to the reader. That's the reason for us to associate him with the negative power of this paw. Even the nature tries to  warn the family about a danger. But still we can name several positive traits of his character. He tries to notify the Whites about defects of the wishes but the family remains the same.

Next character under analysis is  Mr. White, the head of the family. But this  expression may be under suspicious as his son calls him "hen-pecked". Though it's a joke only, Mr. White impliments all his wife wishes. But there's one decision that he makes by himself - the last wish is for his own. He is also a little bit thoughtless as we can see through his chess play. He's also irresolute, he has no idea what to wish at first. That fact that he wishes money to pay for the house says us abount his humanity. Then goes Mrs. White. She's a strong woman who 

holds all the aces in her family. She's smarter then her husband but more impulsive. She's devoted to her family and love all memebers of it. The last personage is Herbert White. He's the subject of monkey's paw magic. He's realy loved son of his parents but he lives for some reason with them. But we can't assert that he's irresponsible or dependent on his parents. He helps them and  is probably the only one working in the family, supporting them all.
