Be careful what you wish for because it might not turn out the way you intended it to be.
The point of the monkeys paw is to show people to be careful what you wish for because it might not turn out how you wanted it to. When you wish for things that aren't needed you can loose something you didn't want to lose or you might gain something you didn't want to gain.
The reason I said that because in the story the family wished for 200 pounds of money but by making that wish the next day they were given a message that their son died at work but they got 200 pounds of money because of the wish they mad. And the 1st man had his 3 wished i don't know the other 2 but the last one was death so you already know it's bad.
For example in the monkeys paw they wished for something that they thought that couldn't hurt them. Then when they receive their wish they also receive bad news. They font out that their son died. Having that money paw is bad u may wish for something that is great but end up losing something or someone in the long run.
Be careful what you wish for because you might get what you wished for but you also might loose something you didn't want to loose in return of that wish. Like the story the author states how " His tone were so grave that a hush fell upon the room" the man brings up the 1st man who wish a pond the monkeys paw.
