Does every LISP S-expression need to have a value (need to be
evaluated)?  Is atributing a symbol to undefined behaviour needed?

Which is why I said, the natural way to have an “undefined” value is
for the computation not to terminate at all.

 
To not terminate is not natural at all, it is also not a natural way.

Unnatural and ungrammatical.

Unfortunately, there are some people that think that they live forever
(being being alive a natural thing), and prefer to spend their limited
amount of time bashing at people who acknowledge natural things, such as
life having death.

Also, programs being stuck in a idle forever loop, is also not natural,
and it is the opposite at what programs are meant to do.

But stupid people may disagree, until, one day, their disagreement
stops, as everything in life.
