Guilt is a complex emotion that arises when someone feels responsible for something they have done or failed to do. It can be triggered by actions, thoughts, or feelings that go against an individual's moral code or conscience. Guilt often involves a sense of regret and remorse over a perceived wrongdoing, leading individuals to feel shameful or embarrassed about their behavior. In some cases, guilt can also manifest as self-doubt or low self-esteem when someone is unable to forgive themselves for something they believe they should have done differently. Overall, the emotion of guilt serves as a reminder that our actions impact others and ourselves, encouraging us to reflect on our behavior and make amends where necessary.
