Given that the Reds killed tens of millions of their own during peacetime, the odds are against it having been as bad the other way.

Many ( most? ) of the killed were not "red" or even ethnically Russian ( see for example https://en.m.wikipedia.org/wiki/Holodomor ). Many of the "reds" were not ethnically Russian either. Your "of their own" doesn't really makes sense.

I meant their own people. People under their rule.
