Why Armand was so repulsed by his child and his wife?

Armand's repulsion towards his child and wife stemmed from his deep-seated beliefs about race and lineage. Upon discovering that his child was of mixed race, he felt a profound shame that challenged his identity and societal status. Additionally, his disdain was fueled by the societal stigma attached to their heritage, leading him to reject both his wife and child as a reflection of his own fears and prejudices. This reaction ultimately highlights the destructive power of racism and the fragility of Armand's self-worth.
