"Of all tyrannies a tyranny sincerely  exercised for the good of its victims
 may be the most  oppressive.  It may be better to live under  robber barons
 than  under  omnipotent  moral busybodies,  The robber baron's  cruelty may
 sometimes sleep,  his cupidity may at some point be satiated; but those who
 torment us for own good  will torment us  without end,  for they do so with
 the approval of their own conscience."    -   C.S. Lewis, _God in the Dock_
