From what Roy knew so far, he had already realized a situation: Don't casually split the soul to create self-aware clones.
The demons of the Abyss seemed to like splitting their souls, either to create weapons or to make clones as helpers. Creating weapons was not too risky since the soul fragments were trapped in non-living bodies, and it was generally very difficult to develop self-awareness. But if they were placed in living bodies, it was highly likely that they would gradually become individual demons over time.
The wills of these new demons would not be consistent with their main bodies. They would not think that they were a part of the main body, nor would they have the thought of returning to the main body. Sometimes, they would even think that they were the main body, and the main body was the clone.
This situation not only happened with demons but also with angels.
