A great deal; you are good to those who are good to you. It is all I ever desire to be. 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.
