A kind Providence has placed in our breasts a hatred of the unjust and cruel, in order that we may preserve ourselves from cruelty and injustice. They who bear cruelty, are accomplices in it. The pretended gentleness which excludes that charitable rancour, produces an indifference which is half an approbation. They never will love where they ought to love, who do not hate where they ought to hate.
