I wonder if if would be a better fit in the Humanism Forum.
Although it’s hard to identify empathy in other animals, someone sent me a series of photographs showing a female bird which had been hit by a car and was dying or dead. All of the things its mate did in the series of pictures were heart-rending and obviously demonstrated empathy.
Social animals sometimes seem to show empathy or caring for other members of their group. We could possibly guess that it’s genetic or at least has a genetic component, however, we see people all across the spectrum - from those who will even carry a spider out of their house rather than killing it; to the sociopaths who seem to enjoy causing pain to everyone and every living thing.
Unfortunately, none of the above answers the question of “why?”.
I feel better about myself when I help others, and feel worse if I happen to hurt someone or something. But, I don’t know why.
And, most annoying is that I often don’t KNOW what they need or don’t want. That’s the empathy part.
