NO!

when you have let some have a root account to fix something (perhaps
the password file itself) you don't want them to casually have access
to all the passwords.  Among other things some of your users probably
have the same passwords on other machines.  Further when a user of
machine-1 wants an account on machine-2 we cna just send the encrypted
passwords through less than perfectly trusted channels and give him an
account with password on machine-2.  if the paswords had to be
unencrypted on machine-2 it would * very* inconvient to do things like
