You’re asking why you are “expected” to have human empathy? I can’t answer that, but I can tell you that you are personally better off accepting and processing other people’s emotions and experiences, than you are refusing to do so. You are better off with compassion and allowing yourself to feel pain than you are closing off your heart and feeling nothing; doing the latter maims you and your capacity to feel.
