your feeling for Dutt is understandable. But your over exaggeration of his dream to see developed India, etc., is unwarranted. As long foolish indians keep selecting and electing scoundrels, there will definitely be many more Rajas, Marans, Kalmadis, pawars, Chavans, etc., who does not want either the country or its people to grow but only their family grow.
Like the love and affection the great blind king of Mahabaratha had on Duryodana though knowing his crude behavior, Dutt also loved his dear son Sanjay and saw to it that his party relapsed POTA and TADA for the sake of his son else Sanjay would be lingering in Tihar or Belgaum jail for life.
Be realistic. I am sure, you will have the same feeling for your near and dear when their time comes.
