Answer:
Empathy is an emotion that one needs to understand the world. A person needs to know what the others are going through in order to fully understand. As they say, in their shoes. A situation has many sides and each person has different circumstances and emotional stamina to deal with them
Therefore to fully understand the complete scenario from where one person is coming and feel what he might be feeling and think on his level, one person needs to be empathetic. A lot of concepts and emotions will surpass a person if he is not empathetic.
