To forgive an injury is often considered to be sign of weakness. It is really a sign of strength. It is easy to allow oneself to be carried away by resentment and hate into an act of vengeance; but it takes a strong character to restrain those natural passions. The man who forgives an injury proves himself to be the superior of the man who wronged him, and puts the wrong-doer to shame. Forgiveness may even turn a foe into a friend. So mercy is the noblest form of revenge.
