I’d say that passion has too much of a positive connotation. I think we should remain within the thematic language already present in this film (and the saga in general). Compassion literally translates as “to suffer with” and I think that’s the perfect way to describe Leia’s approach in life. Even way back in the original Star Wars she was the first one to offer Luke some consolation after Ben’s death. “Empathy” sounds a bit too modern and psychological to me. It’s probably best to remain with this more grounded language.
I really like DZ’s shorter/edited one. I’d just add on the “over hatred” part so it’s a little more clear that their mother’s path is to compassion as their father’s path was to hatred. I think it clears up the sentence structure and just lets things flow a bit better.
