I think that Cardin and Jaune are distorted reflections of each other. They're both descended from men who fought in the Human-Faunus War. However, whilst Jaune's family learnt the lesson of the war - that the Faunus are equal to humans - and moved on, Cardin's family festered in the bitterness of defeat and brought up Cardin to hate the 'animals' who had humiliated his ancestor.

I don't know if it's possible to break conditioning to hate that has been inflicted on him all his life.
