In this case, given that Churchill was prime minister of a colonial power, its more akin to starving POWs while siphoning their crops to a different locale; a crime in any post war court. Your analogy is way off base.
Would also add that part of the crop failures thing is because the British forced the locals to grow cash crops over several centuries. Funny how independent India has yet to have a drought that escalated into a famine and has effectively dealt with droughts huh?
As for "Western society", that you modestly imagine yourself as a representative of/spokesperson for, I'm British. I have never met a single person in my entire life who had a positive opinion of Churchill, with views ranging from contempt to indifference.
Outside of Conservative/Establishment circles, among people who know more about him than a handful of speeches he made, Churchill is rightly loathed. He was an objectively bad person.
He was supported during WWII because, unlike others in the cowardly Quisling British Conservative Establishment, he actually wanted to fight Hitler, albeit for his sense of 'supremacy' over Germany/Hitler than any particular morality.
Once Hitler was defeated, in spite Churchill's ego-maniacal interference in the war effort that caused countless unnecessary deaths and catastrophes, he was rejected by the people in every single general election.
Unfortunately for Britain, and for Obama's grandfather who Churchill tortured along with thousands of others, the "democratic" British electoral system allowed him to become PM again, despite receiving far fewer votes than his opponent.
Sounds like an election Stalin would be proud of.
If a person on the street who is starving asks me for food, and I decline and yell some epithet about the homeless, and keep walking, any reasonable person would consider that less evil than if I shot that person while yelling that epithet.
At the end of the day, the direct cause of the famine were crop failures and the invasion of Burma, not Churchill's inaction. At the end of the day, the direct cause of the millions of deaths in famines in the USSR was Joseph Stalin's mass collectivization.
You should remember it, because, to put it bluntly, if you ever said that in Western society, you would be laughed out of the room.
