"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_
