One does not have to concur with the entirety of Steiner philosophical views to see the wisdom in this insight with respect to the 'elimination' of soul. Of course, only God can create, or eliminate (by capability, not intent or desire), a soul but the concept of being so cut off from the spiritual source by blunting the intuitive and innate awareness of the soul which every human is born with, thereby making it almost indiscernible, is tragically within the realm of possibility. People do it with substance abuse on a daily basis.
