Captain Mirvan physically bullies Madame Duval because he knows he can get away with it, as men had unchallenged power over women in 18th-century Britain. As a woman, Madame Duval has fewer rights and less social power than the Captain. Captain Mirvan partly dislikes Madame Duval because he finds her pretentious—she wears a wig, which suggests that she’s trying to make herself look younger. However, although Captain Mirvan is right about Madame Duval’s being a shallow person, it does not justify his misogynistic violence against her.
