Fire is interesting. It has the ability to cause chemical reactions to change
the basic nature of combustible materials, but it cannot annihilate their
components. For example; fire destroys coal's original form and converts it
into pollution, e.g. CO2, nitrogen oxides, sulfur dioxide, particulate matter,
and heavy metals.
Now, we know from Matt 10:28 that the human soul is able to survive the
death of one's body. But we also know from that same verse that there is a
place whose fire is such that it's able to destroy the human soul.
Is it possible the human soul is similar to most other combustible materials
in that it's constructed with a variety of components; and if so, what happens
to those components when the soul is destroyed in that weird fire? Do they
become pollutants? Can they be collected and recombined to form something
other than a human soul?
The soul of a demon seems reasonable to me because according to Matt 25:41
there is a fire prepared for the Devil and his minions. If the souls of the lost are
converted into demonic beings, they'll fit right in.
