How do Sergeant-Major Morris' comments foreshadow the harm that the monkeys paw will cause?

Two remarks from the text:

“The first man had his three wishes. Yes,” was the reply, “I don’t know what the first two were, but the third was for death. That’s how I got the paw.”

“I won’t.” said his friend with stubborn determination. “I threw it on the fire. If you keep it, don’t hold me responsible for what happens. Throw it on the fire like a sensible man.”
