the answer to this for me is it depends as there will be so many more emotions in the mix that attach to love and empathy- I enjoy my self love when it arrives and I guess for me different feelings are rising adn falling constantly some harmoniously some not and how I respond is different each time. and each situations. I think that is what is interesting about being alive and having interesting times.

Neither. It's a basic human response that keeps us looking out for each other. Some people don't have it.

I would say love is the motivator. Empathy must be a by-product.

in my experience there is no clear differentiation between love & empathy - & no need for one.
