Dou is overall amoral, arrogant, brutal, cold-blooded, hypocritical, manipulative, seductive, unreliable, but brave, charming and honorable anti-villain. Xingzuo Temple needs anti-villains and anti-heroes. And remember, none of the Zodiacs are supers, they are simply well-trained beings hired for various duties. Dou's job is either dominatrix or an killer, idk. How much cash she got?
Does Dou make a good mother? I indicated that she must be related to Xigua because of similar traits and overall chemistry.
