Personally I tend to think that the Bengal famine is better compared to the Holodomor, as it is closer in time, area, and effect. If there is a lesson to these things though, I think it’s that it doesn’t matter what economic system you use of the people in charge are fans of eugenics, and that’s why it’s so important that there be strong independent checks on the government and politicians, minority representation, multi-party rule, etc…
