Analysis of information sources in references of the Wikipedia article "Suicide Squad" in English language version.
Nobody really believes that a hero will get killed in their own book, so it can be hard to bring tension to the fight between good and evil. But when every team member is as unimportant to the publisher as they are to the fictional setting in which they exist, death can be around the corner. As the Suicide Squad book killed somebody in just about every story arc, readers got hooked on the idea that nobody was safe.
