> That is a delusional take on the Bolsheviks.
I don't really want to argue in detail about the character of the Bolsheviks. I agree they were extremely ruthless, and that they created a lot of the norms and institutions that Stalin later used.
Taking a bit of a step back, however, I think most of this stuff is pretty normal for the winning party in a civil war, especially a revolutionary party. It was an extremely chaotic situation, and if they were not the kind of bloody-minded, ruthless people they were, it's really unlikely they would have been successful.
If you take the Finnish civil war, for instance, there was systematic use of terrorism by both sides, and in the aftermath, the victorious whites essentially went on a political purge, imprisoned socialists en masse, etc. The 'whites' in Korea killed hundreds of thousands of 'communists' and 'suspected communist sympathizers' during the Korean war. The liberals in the French Revolution (Robespierre, etc) killed enormous numbers of people. Civil wars are like that. Revolutions are like that. As 'winners' of this kind of thing go, the Bolsheviks are really pretty mild.
Ultimately, I think the Tsar's Russia was a deeply sick system that had to go, one way or another, and if the Bolsheviks had not had Stalin, the period of violence would have turned into a normal state with a fairly normal post-revolutionary democratic deficit, that would have been resolved in a way compatible with the (actually very lofty) goals of the revolution.
