What does mr white complain about so violently and what does his wife think he's really angry about?

Mr. White complains violently about the loss of his son, Herbert, and the consequences of using the monkey's paw, which he believes has brought tragedy to their family. His wife, however, thinks he is truly angry about the misfortune and the grief of their loss, as well as the futility of trying to change fate. She sees his rage as a manifestation of his deep sorrow and frustration over the situation rather than just anger at the paw itself.
