With 8 billion people in the world, even with the 4 billion when I was born, there's enough genuine evil[0] in the world to wreck anyone with even the slightest capacity for empathy. I have no idea if this documentary is or isn't at that level, because I have enough going on without wading into Indian politics.

Will this documentary cause its viewers to end whatever specific ills are shown within? I presume so, otherwise it wouldn't be getting censored.

Will it cause any specific person to effect that change? Probably not, most of us have no influence whatsoever over Indian politics or economics.
