In one of the recent interviews I did I was asked if I thought there existed in our world bodies without souls. As I recall my reply was somewhat non-committal and I said something along the lines that everyone has a soul but some people by their choices, their actions and their thoughts may have cut themselves off from their souls to such a degree that they could be regarded as soulless entities.
I didn't want to get into anything too esoteric in these interviews because they were about the Earth is a School idea and I wanted to keep the discussion simple. However, the world is currently under an occult attack of such proportions that it is incumbent on all religious people to deepen their understanding of the supernatural realm, the better to withstand this attack. What is taking place is part of a longstanding scheme to enable demonic forces to get a greater grip on the material world and human beings. Their plane of existence is largely cut off from the source of spiritual energy and so they want, perhaps even need as a matter of survival, to interact in some way with the physical world where they can have access to life energy. This they have previously done through attacking the energy fields of human beings, chiefly emotional but mental and vital too, but the growth of technology has given them other means of achieving their ends, and I would suggest that one of the methods they are developing is incarnation in the physical world through computers. Artificial intelligence can never in itself be anything more than mechanical but it is possible that demons could use it to interact with the physical world and, in that sense, it might become real. Computers are surely one of the greatest sources of evil ever to have afflicted the human race. Yes, I know I am using one now to write this but that really isn't the point. What computers do is reduce human beings and a large part of human consciousness and many aspects of human relationships to the quantifiable and the mechanical and the easily controllable. Basically, to the inhuman. I'm sorry if this offends some readers but, be honest, look at the world and how it has changed over the last 50 years and is changing increasingly. Can you deny what I say? And this is just the beginning unless something derails the process. To use the terminology of Rudolf Steiner, computers are the manifestation of Ahrimanic evil.
What is man? Essentially, a human being is various intermingling fields of energy, spiritual, mental, emotional and physical, to keep it to its basics. The lower levels are the ones we normally function in on the material plane but these only have life in them because of the higher levels. It is the soul that animates the mind and body. Now, through wrong thinking, wrong imagination, which is both the creative and destructive force within us, wrong exercise of the will and wrong action we can separate ourselves from the source of our life to such a degree that we isolate ourselves on the physical plane. We can actually sever our contact with the soul, our spiritual core, so that it may continue to give life to the material side but that is all it does do for the consciousness has descended so far that it is locked in the material. It has erected a wall of darkness between itself and the spiritual. This is effectively a body without a soul. The soul is still there on its own level but contact with it (influence by, perception of) has been completely lost. This can be perceived by someone spiritually attuned in this world. You can perceive it in many people currently in positions of power. The eyes are indeed the windows to the soul. There is an emptiness in some people's eyes, a blankness.
Demons are beings in whom this process has been taken to its conclusion. They are non-physical but non-spiritual in the higher sense too. This means they have severed the connection to the spiritual and therefore to the life force. That is why they must steal energy through various means from incarnate humans. Because they are non-corporeal they are not bodies without souls but they could be seen as minds without souls.
Soulless entities are not necessarily evil in the conventional sense though those who are evil in that sense could potentially fall into this bracket, beings absorbed by their own shadow and open to domination by the aforementioned demonic forces. But you can be intellectually evil too and those cold, calculating, highly intelligent individuals who have, according to their own estimation, used logic and reason to dispel the notion of God also risk turning themselves into soulless entities. These would perhaps be defined as Ahrimanic evil as opposed to Luciferian evil, again using Rudolf Steiner's helpful terminology. They will be more defined by pride and lack of love than one of the 'hotter' sins such as lust, greed or selfishness. They can be capable of living almost like monks in terms of poverty, chastity and obedience (obedience not to God but to the laws as they see them of reason), but the motivation for this is purely intellectual and utilitarian. Cold and dead. There is nothing spiritual behind it at all. Study such types and you will see that there is never anything spontaneous about them. Everything is done from calculation. They will be drawn to computer technology because the mindset behind that represents their worldly ideal. Everything can be quantified, controlled, reduced to data. As I say, these people will not seem evil by the traditional standards but they are anti-God, anti-creation, anti-love, anti-beauty and if that is not evil I don't know what it is.
Before concluding there is one other aspects of the question I'd like to address. According to some esoteric teachings not all human beings have the same origins or come from the same source. Some have come down from higher worlds and so they are souls that have incarnated in matter to further their spiritual development. But others have risen up through the material side of existence. These people, usually fairly simple and primitive in consciousness, have not yet developed a soul. They are in the process of doing so and their life trajectories will lead them to that end if faithfully followed. Of course, this won't be a popular thought today but why should all human beings be the same in terms of their origins? Once you accept a spiritual world you can see how improbable that actually is.
But these souls are not evil in any sense, certainly not in the way the soulless entities who have cut themselves off from their spiritual side have made themselves to be. They are simple, more attached to the material world than most and more obviously belonging to that world. They will be less intellectual in outlook but quite capable of creativity and accomplishment in terms of their consciousness. You might think I am referring to one particular class of people but I don't think these types can be defined in terms of human groups. They could be in all groups though most probably in some more than others.
Everybody in this world must have some spiritual contact or else they would die. But there are some who have, to a greater or lesser degree, cut themselves off from their souls because of wrong thinking and perverted will. For this is not just a matter of ignorance. To lose touch with your soul is chiefly the result of a will that has turned against God and creation. The root of all sin is in the will.
