If people were always kind and obedient to those who are cruel and unjust; the wicked people would have it all their own way: they would never feel afraid, and so they would never alter, but would grow worse and worse. When we are struck at without a reason, we should strike back again very hard; I am sure we should — so hard as to teach the person who struck us never to do it again.
Jane to Helen Burns (Ch. 6) - Jane Eyre (1847)
