What are the motifs in Johnny the Homicidal Maniac: Director's Cut by Jhonen Vasquez?

Vengeance plays a vital role in the novel as one of the primary themes in nearly all strips. First, Johnny spends much of the novel seeking vengeance against those who have treated him badly over the course of his life. While it is unclear what happened to his parents, Johnny kills strangers, friends, and acquaintances in an effort to stop the pain he feels after years of abuse by humanity. His vengeance is violent, cruel, and often involves severe torture. Additionally, his victims often threaten vengeance against Johnny as they wait to die, wanting to inflict pain on him for the fear he has caused in them.
