The answer is guilt. When someone feels guilty, it means they have a sense of remorse or regret for something they have done or failed to do. Guilt is a learned emotion that can occur when our actions or decisions go against our moral values or beliefs. It serves as an internal alarm system, signaling that we have done something wrong or failed to meet our own standards. This feeling of guilt can serve a purpose by motivating individuals to correct their behavior, make amends, or learn from their mistakes, helping them avoid repeating the same wrong actions in the future.
