As well as the fact that Elizabethan theater had its rules about how a revenge tragedy had to be, so did Thomas Kyd. He came up with the Kydian Formula to distinguish revenge tragedies from other plays. His first point was that the fundamental motive was revenge, and the revenge is aided by an accomplice who both commit suicide after the revenge is achieved. The ghost of the slain watches the revenge on the person who killed him. The revenger goes through justifiable hesitation before committing to revenge as a solution.
Madness occurs due to the grieve of a loss.
Intrigue is used against and by the revenger. There is bloody action and many deaths that occur throughout the entire play. The accomplices on both sides are killed. The villain is full of villainous devices. The revenge is accomplished terribly and fittingly.
