that COULD have done something good for the world<

That is of course what we as premies believed - and looking back it still seems as though the opportunity SHOULD have been there. But realistically Rawat never could have been a force for good - by the time he was faced with the temptation of power he was already ******UP, and whether one blames his family or his adoring fans or just some biochemical eccentricty of Prem's neurology, he is and was always was going to be a sociopathic narcissist. 

The enduring charge against Rawatism is not one of "what he could have been" but "for evil to thrive it requires only that good people do nothing"  - Rawat was allowed to thrive by "good people who should have known better".
