Stress can influence ethical behavior in complex ways, often depending on the individual and the specific situation. While some people may become more stubborn under pressure, others might falter and compromise their ethics. The discussion highlights that morals are not fixed and can be flexible based on circumstances. Historical examples, such as studies demonstrating how ordinary individuals can commit extreme acts under stress, illustrate this variability. Ultimately, everyone possesses the potential for both good and evil actions, influenced by their circumstances and stress levels.
