It's more instinctive to want revenge, but we are also capable of immense amounts of forgiveness and love and a compassion that extends even to those who have brutalized us.
Mandela is this extraordinary individual who can inspire the world. Instead of wanting revenge after being brutalized, he showed the world how to forgive.
I'd like to believe that I would be able to give in the same way Mandela did, but in reality, I don't know whether that is true. It is much more likely that I would be left with an immense sense of injustice and immense desire for revenge.
