You're absolutely right. I was trying to be concise and in turn made it sound pretty accusatory.
There has been a number of investigations by both the British and Indian governments since the famine. The general consensus is that it was caused by bad management and unresolved socio-economic issues over any purposeful acts of cruelty.
I personally don't think Churchill actively encouraged the famine in India, but he was an ardent supporter of maintaining the empire by any means necessary.
Stalin, Pol Pot and Mao Zedong have all committed atrocities far worse. And I do agree that Leopold belongs on that list too.
