This saying indicates that a person takes revenge upon one who does some harm to him to who causes or puts in some danger. By taking revenge the person tries to soothe his aching heart and pacifies his mental imbalance or humiliation that one causes. When a person is badly hurt or put into trouble by others, one gets angry and loses the mental imbalance. So instead of pardoning one damages physically.
There is a tale in Panchatantra in which there was a rogue elephant which always troubled the smaller animals like the frog, the ants and the birds who have laid their eggs. Once he shook a tree for fun and broke the eggs of a bird. The bird was very angry and wanted to take revenge. It had a discussion with the frog and the ant and then they decided upon a plan. The bird came our and pecked at the elephants eyes with his sharp beak. The ants climbed and bit him very much. The elephant wanted to wash his head in water. But he was blinded and could not see anything. At this time the frog started croaking at the top of the mountain. The elephant followed the frogs’ voice and climbed the mountain and fell down from there and died. Thus the bird and the rest of the animals took their revenge against the rogue elephants for his misdeeds.
