That old law about 'an eye for an eye' leaves everybody blind.
The person who pursues revenge should dig two graves.
Revenge has no more quenching effect on emotions than salt water has on thirst.
No revenge is more honorable than one not taken.
Never does the human soul appear so strong and noble as when it forgoes revenge and dares to forgive an injury.
Revenge is often like biting a dog because the dog bit you.
Keeping score of old scores and scars, getting even and one-upping, always make you less than you are.
