The similarities between The Whites and Pandora is that they both had curiosity of these objects that were brought to them. They were both curious about what they would do and how it would effect their lives. But they didn't know that they would lead to something really bad.
Some other similarities between The Whites and Pandore is that both got too curious and it led to something bad. The Whites son died and evil was released when Pandora opened the box Hephaestus told her not to open. So both of their curiosity levels got the best of them.
The paw caused the son, Herbet to die in the machinery at work and the box caused all the evil stored inside of it to be relased into the world. So Pandora didn't have a major personal loss but the The White's had a major loss. The consequences for The Whites were more severe than for Pandora personally.
Why was Pandora given this box and why were The Whites given this monkey's paw? Why did these certain consquences happen to The Whites and Pandora? Why did they make the box for Pandora and why did Sergeant Major chose The Whites to have the paw because one was a normal family and one was a Goddess.
