This chapter applies symbolic learning theory to compare Abu Bakr al-Baghdadi, the former leader of ISIS who advocated ritualistic suicide attacks, and Lord Voldemort (the arch enemy of Harry Potter in J. K. Rowling’s series and the leader of the “Death Eaters”). Symbolic learning theory postulates that the repeated use of mental imagery facilitates memory and subsequent performance of activities. In other words, through mental practice, the learner creates a mental blueprint by familiarizing him- or herself with the symbolic elements of a task. Both Abu Bakr al-Baghdadi and Lord Voldemort were power-hungry, heartless, fascist leaders on the “dark side.” While the former was the self-proclaimed “caliph” of the Islamic State since the summer of 2014, the latter is the self-proclaimed title for a Harry Potter character who is the “supreme ruler” with a prophetic ability to annihilate the Dark Lord. An important conclusion of this conceptual analysis is that symbolic learning theory reveals how both leaders wanted to “purify” their bloodlines by eliminating their evil enemies. Still today, particularly in the case of ISIS, it is done through techniques like suicide terrorism. Suicide, here, is to be performed as a blood ritual. This is where the theory’s concept of mental imagery comes into play. Although Lord Voldemort does not advocate suicide terrorism per se, both leaders nevertheless have inculcated mental blueprints of “blood purification” into their followers so that they fully perform violent murder and torture on their enemies.
