They are not madmen, just alchemists with a curiosity that runs deeper than most.
This curiosity may lead them to slightly violate some of the stipulations of the alchemist's guidelines, but it doesn't drive them into madness, unless they make a crucial discovery in their experiments with soul fusion.
And yet, apart from filling up countless papers with records of their failed experiments, they had reaped nothing more to this point.
"We were fusing animal souls in the hope of creating new ones, crafting new beings and discovering their patterns through continued observation and experimentation, thereby manufacturing useful souls. If we were to use human souls, would the newly born soul possess human characteristics? If so, would it bear the rights and responsibilities of a human? If not, then our fusion process is essentially murder." The remaining alchemist expressed his views.
He could not choose to remain silent.
