If you want to iterate through a list, should you use a recursive

Unless you have a very good reason for reinventing your own list
iteration, you should use what's already in the Common Lisp library.
So yes, one possibility is a loop. But not just any loop, but
specifically the for-as-in-list or for-as-on-list clauses of the LOOP
macro. Then there is DOLIST, the mapping applicator functions--MAPC,
MAPCAR, etc--and of course the sequences library, which combines
iteration with useful algorithm: REMOVE-IF, FIND, EVERY, ...
