Albeit it took longer and it was "gradual" but few of them had the hyper-violent post "vanguard" revolutions events that resulted in some of the worst tragedies in history?

Almost all violent revolutions have resulted in a stain on world history. Yet the (less news worthy) numbers who gradually adopted independent courts and shifted from monarchy to republican/parliamentary power are much higher, and none of them had awful mass murders of people whose ideas weren't "in line" with the revolutionary ideology, not long after the revolutions.
Anyway, it's a fallacy to think that Russia would be fine without the Revolution. Peaceful transitions to liberal democracy are an exception that only happen on very particular cases.
