Throughout That Time I Got Drunk and Saved a Demon, the characters grapple with doing what feels right to them in moments of conflict. By embedding ethical dilemmas within a fantasy setting, the novel explores real-world questions about morality, justice, and how misinformation shapes behavior. As seen by how attitudes are changed as a result of demons themselves and learning the truth about Myva, the novel explores the choices inherent in doing what feels right. When Cinnamon and Fallon arrive in Wandermere and learn how demons are treated in the city, Cinnamon feels conflicted because she has learned that demons are not mindless, violent creatures. Thus, she struggles to reconcile collaring Fallon so they can accomplish their mission (doing something wrong for a good reason) and refusing to collar Fallon but risking the mission (doing what feels right but putting the task in jeopardy). Ultimately, Fallon decides that wearing a collar (a temporary injustice) to destroy the phylactery (breaking a greater injustice) is worthwhile, which shows the complex nature of right and wrong. Neither Cinnamon nor Fallon is comfortable with Fallon being forced to wear a collar that marks him as inferior when he is not.
