In my essay, I illuminate evil from the perspective of whether we can explain evil deeds through the perpetrator's narrative. As an object for my study, I have chosen a popular culture perspective - the character The Joker - which has been portrayed several times. The purpose of the essay is to study if we understand and can come to terms with evil deeds if we also know the perpetrator's narrative. The starting point for this reasoning is the question of whether evil deeds can always be defined as evil? I have limited my thesis to be based on theories based on traditional and historical research in the field of evil. The material I have used for my analysis is limited to the shape of The Joker in the script of the films The Dark Knight and The Joker. Methodologically, the essay is based on textual idea analysis - around evil and myths.  Out of the scripts of The Joker and The Dark Knight I have developed a hypothesis which I finally discuss the reasonableness and test logically. Theoretically, I have based my study on Lars Svendsen's analysis of evil, John Martin Fischer's analysis of the meaning of the narrative and Claudia Card's discussion of grey areas. Based on these, I have analysed, discussed and argued to test my hypothesis and answer the question of the essay: Is The Joker's narrative an explanation for his evil deeds? The study's method and analysis have generated a result that shows that this is not the case. The Joker has made his own free choices that have made him who he is and what he does. His narrative is not an explanation for his demonic evil deeds.
