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.
