The Irish potato famine, or the famines in India were absolutely caused by malevolence. You don't 'accidentally' have a famine in a country that is, in the middle of the famine, is a net exporter of food.
The Irish famine is in particular awful as the British wrapped themselves up in heart-wrenching moral concerns. They wouldn't want the poor Irish wretches becoming dependent on charity -- so what if the pig eats better than the farmer.
I didn't say it wasn't caused by malevolence. But it wasn't caused by "capitalism" as an organizational structure for the economy. My point is simply that while capitalist countries often kill people through malevolence or negligence, socialist countries do both of those things, and are also uniquely adept at killing their own people by destroying previously functional production systems.
