A_Real_Werewolf234
this does not explain how he can speak and how he knows the language... it could be explained by the fact that the memory remained in the souls (but you already said that the souls were completely purified). It can also be said that artificial intelligence (which can develop) was created by Satan Ajuka through the magic of inscriptions and rituals on pure souls. (but you just left a hole in that question) as well as his unprogrammed loyalty and the fact that he speaks and knows the language... it's too weird (more like a plot hole)
