What are the motifs in The Little Foxes by Lillian Hellman?

Revenge is a reoccurring idea in this play. If audiences find anything to admire in the detestable maneuverings of the Hubbards's rivalry over money and power, it is in the vengeance one evil character wreaks upon another. This play does not offer the grand satisfaction of a strong and good hero winning retribution for harm done in a dramatic moment of victory.
