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