Capitalism is the only economic system that has the privilege of being evaluated outside of the context of the society in which it exists. When socialism is criticized the political system is always, justly, included; so the purges of Stalin and the homophobia of Guevara are all taken into account. Apply the same thinking to capitalism and you have to count a lot more deaths and injustices: the Irish and Bengali famines, world war 1, climate change, etc.
Add the East India Company's rule in India to the list, 40 million deaths on a conservative estimation.
