How many unrelated people were executed or imprisoned during and right after 1917 and 1905? How many of the revolutionaries were 'removed' by their own for sticking out?

During the civil war and afterwards, how much the fate and life of common people depended on the whim and 'perception of loyalty to X' ? In order to prosper (or even survive) your allegiance would have to be flexible enough to adapt quickly, or you'd get eliminated. As the saying goes, 'the tall poppies get cut first' - no matter if you were for or against the revolution.

1917 was a result of picking a fight with authority, but the aftermath of 1917 was to eliminate anyone else who'd pick a fight with authority - both outside and within the revolution.

This is what I mean by 'keep your head down'. There's a curse "may you live in interesting times". Living in such times teaches you and the whole society to be mindful about what you say, careful if your beliefs are perceived as proper, and not to pick a fight with authority.
