What is the definition of a revenge tragedy?

A revenge tragedy is characterized by its central theme of vengeance, where a protagonist seeks to avenge a wrong that has been committed against them or a loved one. This form of tragic drama often involves complex moral dilemmas, psychological conflicts, and typically culminates in violence. It explores themes of justice, retribution, and the consequences of revenge on both the avenger and the society around them. Works like Shakespeare's "Hamlet" or Kyd’s "The Spanish Tragedy" exemplify this genre, as they depict characters driven by the desire to rectify perceived injustices, often leading to tragic outcomes.

The other options highlight different aspects of drama but do not encapsulate the essence of a revenge tragedy. Familial relationships, heroics, and comedic resolutions fall outside the traditional characteristics that define the specific genre of revenge tragedies.
