A guilty feeling is an emotion that can be caused by a variety of situations, such as regretting a decision or feeling responsible for something bad that has happened. It is often described as a combination of REMORSE, SHAME, and PANG. REMORSE is a deep regret or sorrow for a wrong committed, while SHAME is a painful emotion caused by a strong sense of guilt, embarrassment, unworthiness, or disgrace. PANG is a sudden sharp feeling of physical or mental pain. All three of these feelings can contribute to a guilty feeling.
