Was the Cardicra Family strong?
Yes.
Could Faye make someone disappear from the face of the world without anyone knowing it?
Without a doubt.
Those were facts, but they couldn't be shown to the public. It was the dark side of the aristocratic world that ran counter to their public facade. If they showed this, it would bring shame to them.
France was a country that espoused the values of equality and democracy. If what Faye said was released to the public, it could cause an uproar.
Faye was no ordinary person. She was one of Cardicra's successors. She was someone whom Eric treasured.
If she were known to have this line of thinking, everyone would be pondering how she turned out like this.
Questions would inevitably be directed toward the Cardicra Family. Were they this disdainful about the sanctity of life and justice?
