There is a saying that goes along the line, "If it has happened before, it can happen again."
There is another saying that buttresses that saying. It is, "There is nothing new under the sky."
What these sayings imply is that history repeats itself and we should look to the past to predict what is possible in the future. These sayings insist that one should learn from the past.
It is because she has learned from the past that she believes that it is possible for the god of justice to die. She is not the only judge who thinks this is possible.
Not only do judges think that it is possible for the god of justice to fall and for the church of justice to become a cult like the cult of blood, but some judges even consider replacing the god of justice. After all, that is the only way for them to become gods.
