It's hard to pull apart empathy from compassion. What is really clear is that we innately care for other people at least to some extent.

My brother is severely autistic, so when I was a kid I spent a lot of time as a teenager in camps and programs for autistic kids. When I went to McGill as an undergraduate, I figured I'd be a therapist working with these kids. The truth is, and I knew this even back then, I'm just not good at this. I'm too empathic to do this sort of thing.
