I think the Leatrice is also influenced by the cursed objects. Since the objects are passed down from the first Lagrange, maybe the previous heads of the family as well as the current one know about it. I'm guessing since the Lagrange family gets their powers from demons maybe they need to raise their kids to become powerful and evil so they can rule over the demons that they summon?
OMFG HE WENT ALL OUT ALSKSHSJ
