But if we are to follow the lore of the ADD world, everyone has a soul(even demons and angels), they need it to live and exist. With no soul they have no life.
In this world if you make a deal with a devil, they are promised your soul, but they don't actually receive it until you die.
They use the memories of the soul to add to their personal power, then they send the newly fresh soul off into the void to be reassigned as an angel, demon, or mortal again.
