A person with feelings of inferiority can become dangerous when given authority or influence, as they may try to control or dominate others to compensate for their insecurities. The quote from James Patterson's "The Murder House" highlights how power can amplify underlying issues, leading to potentially harmful actions. This suggests that understanding and addressing underlying insecurities is crucial before granting someone authority, as unchecked power can turn a vulnerable individual into a threat. Recognizing these dynamics helps prevent abuse and maintain balance within relationships and organizations.
