Envy is an emotional response that occurs when a person desires what someone else has, such as their success, possessions, or qualities. This feeling can lead to resentment and dissatisfaction, as individuals compare themselves to others and feel inadequate. Envy is often considered a negative emotion, as it can harm relationships and lead to unhealthy behaviors. In psychology, envy is categorized as a complex emotion that can vary in intensity. It can motivate individuals to improve themselves or, conversely, lead to destructive actions. Understanding envy can help people manage their feelings and foster healthier relationships with others.
