"When a stupid man is doing something he is ashamed of, he always declares that it is his duty"

This quote by George Bernard Shaw talks to the concept that people frequently use the concept of responsibility as a method to justify their actions, even when they know those actions are incorrect. It suggests that when someone is doing something they repent of, they will typically try to justify it by declaring it is their task. This might be seen in a variety of circumstances, such as when somebody is asked to do something dishonest at work, or when someone is asked to do something that goes against their moral code. In these cases, the person might feel embarrassed of their actions, but will still try to justify them by claiming it is their responsibility. This quote serves as a tip that we must constantly be mindful of our actions and be honest with ourselves about why we are doing them.
