I guess you also read the bloodsmoking account of Delphine Laurelindoria or something, of New Orleans, who supposedly inflicted such surgical and anatomical atrocities on her slaves that she was seen as worse than totally insane, as demonic ! The mob,maddened by such insane rumors,hideous from growing in the telling, stormed her house, hoping to make her alive into chopped meat, -but she had already fled to France. So they took out their fury on the furniture, smashing it into kindling ! Her victims may have been slaves, BUT you must not treat even animals the way they claimed she did.
You probably read the account of Delphien LaCourtenay or whatever in the same Wikipedia article as the Blood Countess.
Before her bast husband died (killed ?), he had some children by her. There are descendants of her to this day, incl. 3 on Long Island,NY. (!) Wonder if they want it widely known about their ancestor.
As a child, she was fascinated to watch the cruel executions meted out to minor malefactors and looked forward to them. The people must have been a subhuman race.
