AppLeo, I see your point of view: Since empathy, in the sense of being "empathic", is on a purely personal level, we can put sympathy and apathy on that level also. Which means it's possible to be socially engaged and active in helping others, and socially sympathetic to the plight of others you don't personally know, while being apathetic as to how how you affect the feelings and welfare of those you really are in personal contact with. A lot of people have that separation. I'm just not sure I'd single out any particular Sign for that. You mentioned Aquarians as being known for possibly neglecting their own families but helping others. Cancers are known for protecting their own families, while possibly not caring (being apathetic) about what happens to anyone else. And, that Leo's concerns are mostly about themselves. Sympathy can also be extremely selective.
