Venezuela's bloodiness is in part because of CIA funded violent opposition. Venezuela while a basket case now, is still a "what if" in a world without CIA interreference and unilateral sanctions.
China is odd. It is an autocratic repressive regime with their recent founder having the 2nd highest body count of any leader. But, it is also the most impressive story of raising an slice of humanity from poverty into a strong middle economy.
Western countries think about peace & human rights in isolation. What recent democratic nation has managed to elevate itself from abject poverty to being a strong middle economy, with no natural resources ride to infinity. India might have something to show over the next 30 years, but as of today, they started off richer than China at independence and find themselves miles behind. All of Singapore, Taiwan, Korea, Thailand & Japan had their growth occur under incredibly repressive govts. They might seem peaceful countries today, they certainly weren't that during their growth.
> moral equivalence
Moral equivalence can only exist when all other variables are the same. Norway might claim moral high ground on account of being an egalitarian nation, but its entire economy is oil. Remove the oil, and you might see their claimed unwavering morals waver.
