Well you have a point on the part of the pure-blooded devils.

But I have to disagree with the Evil Pieces, they are created because the devils population dwindled greatly because of the Great War.

Even the Heaven adopted the system when they got their hands on it because the "God from the Bible" died which means that Angels cannot be created anymore.
