Probably no unrelated people at all were executed or imprisoned in 1917 or 1905. Even for the most frantic career revolutionaries it wasn't uncommon to flee from the deportation and live illegally in Russia or to emigrate.
I don't think what you are describing is in any way specific to Russian Revolution and Civil War. If reasoning like that is justified, you can 'prove' the same thing about any society that lived through a social calamity.
"Probably no unrelated people at all were executed or imprisoned in 1917 or 1905" -- are you serious? Really?
There were bloody purges after 1905 enforcing 'summary punishment' against, say, everyone living in a specific village, in order to make a warning for others. My local area lists 500 official executions of revolutionaries, but 2000+ 'collateral deaths' happened in the process.
1917 was followed by (1) a civil war, (2) class warfare - reprisals against millions of people where the fact if you were killed or deported was determined in part by wealth, but in part by your connections and local denouncements. (3) internal conflicts such as Tambov rebellion which also meant that you can easily lose everything for something your neighbor did.
Most societies that lived through a social calamity did not endure long periods of internal treachery affecting not a small prosecuted minority but huge parts of population - well, Pol Pot and China Cultural Revolution did, but I'd argue that they had similar effects on their societies.
