Radicals are required for a number of biochemical reactions.  Nucleic 
acid biosynthesis depends upon free radicals.   The immune system 
chemical nitric oxide operates by free radical means.  Simple metabolism 
unavoidably produces radicals as a matter of course.  If they were 
eliminated, metabolism would cease.  The problem is uncontrolled 
radicals.   Those are damaging.
