Actually, Fang Zheng knew why Emilia reacted more strongly than others because she is a Half-Elf, and in Lugnica, Half-Elves are just like Goblins, universally hated for no reason. Therefore, when she saw Goblins, Emilia instinctively grouped herself with them.
This is a case of not distinguishing right from wrong.
However, Fang Zheng also understood that merely talking would not make Emilia understand.
It's not that Emilia is stupid, but the civilization level of this world is like this; philosophical and ideological theories have not developed to a higher level. In fact, Emilia's current views on good and evil are similar to those from rural areas in Fang Zheng's era. They have simple values and relatively honest views, but when faced with slightly complex issues, they freeze up.
