It is not uncontrolled "overproduction". It is better to
think of them as necessary evils.


As with any process where evolution occurs, we (i.e.
humans/mammals/animals/cellular life forms) are the result of 
a number of compromises. One part of our system wants to produce
lots of free radicals whereas other parts don't. So we have a 
compromise where enough are produced to help fight disease but
sufficient to cause problems with cellular degeneration later in
life.
