Empathy is one of the most beautiful human traits. It is the basis of all behaviors that we associate with "goodness" and is the source of compassion, altruism, sacrifice and mercy. On the other hand, lack of empathy is the basis of most destructive and violent behaviors, that is, everything we associate with "evil". In order for a person to behave pro-socially, one must first have developed two abilities: taking a different perspective (seeing a situation through the eyes of another person) and empathy (experiencing emotions felt by another person). Between the second and third years, empathy for the feelings of others begins to emerge. No statistically significant differences were found between boys and girls in the results of the study of empathy, prosocial behavior and temperament. In the EASI Child Temperament Questionnaire, the results show that boys are more active than girls, while girls are more social than boys. It was assumed that older children would score more on the empathy, prosociality, and temperament scales, but statistically, children of different ages did not differ significantly in the results obtained. All subscales of the empathy and prosocial behavior questionnaires were statistically significantly moderate to strongly positive. The strongest link was found between the results of the empathy and cooperation sublevel.
