The phrase about omelette and eggs (or rather its direct counterpart, about timber and chips) ended up as the unofficial primary justification for Stalin’s Great Purge, so the point about strange bedfellows stands. Twentieth-century Russia is in general a good example of what happens when you systematically eradicate the country’s elites, regardless of how unfairly they have gotten into the position or how miserable everybody else is.

The broader point, dating back to at least the French Revolution, is that once you establish the precedent that killing opponents is a way to win, it only takes a decade or two before the most ruthless killers become the winners. All proxy metrics are bad, including electability, but this one is especially awful. I’m more puzzled by why some violent movements do seem to have had some success than by why most didn’t.
