The Duchess of Malfi contains elements of the revenge drama, a popular form in 17th century because audiences enjoyed the onstage violence and bloodshed. However, it also veers from the classical revenge drama. In a purer revenge drama, such as Hamlet, a hero takes revenge on someone who deserves punishment in order to restore justice and honor to a corrupted environment, but in this play, the brothers act violently against the Duchess not because she has overtly dishonored them, but because they don't like that she has remarried. Their revenge is thus not legitimate. Further, the Duchess, even though the play's heroine and title character, dies before getting revenge on those who hurt her. However, the play does include many dead bodies, a salient aspect of this genre, and Bosola, in a change of heart after participating in their murders, decides he wants to avenge the Duchess and Antonio. Moral corruption, a mainstay of the revenge drama, saturates this play. For example, the Cardinal, who should be an exemplar of Christian chastity and virtue, not only has a mistress, but also murders her.
