Retaliation retards your excellence. Nelson Mandela would not have been named as a great man if not for his courage to forgive those who schemed and plotted it for him to spend those 10000 bitter days in prison.

Those 10000 days in prison, but this never made Nelson Mandela to leave what he was doing. He loved what he did and he would repeat to again if he had been arrested again and imprisoned again! He has his bigger picture in view!
