Okay, but it clearly demonstrates that the framing of Lenin as the fascist scumsucking mass-murderer-in-waiting that he was does not require hindsight, as numerous socialists at the time, by your own admission, recognized that fact.
That's... not what I was saying though? Whether Lenin had the makings of a tyrant or not, he had to have believed in the revolution or he wouldn't have dedicated his life to it (which, love him or hate it, that's exactly what he did). Lenin had been a professional revolutionary for more than 20 years by 1917, and the idea that this was all an act so he could eventually seize ultimate power is frankly ridiculous without some hard evidence. Extraordinary claims require extraordinary evidence.
That is an incredibly naive position to take. People willingly suffer for all sorts of fucking reasons, and principles are pretty far down the list.
I mean unless he got himself expelled from university and derailed his career for material gain, it'd have to be principle.
He also didn't espouse socialism in public.
"Why," I asked Hitler, "do you call yourself a National Socialist, since your party program is the very antithesis of that commonly accredited to socialism?" "Socialism," he retorted, putting down his cup of tea, pugnaciously, "is the science of dealing with the common weal. Communism is not Socialism. Marxism is not Socialism. The Marxians have stolen the term and confused its meaning. I shall take Socialism away from the Socialists. Socialism is an ancient Aryan, Germanic institution […] We demand the fulfilment of the just claims of the productive classes by the state on the basis of race solidarity. To us state and race are one."

So your answer to the question is 'no'.
No? The answer to my question is "Hitler," but also of these the one I know is Kai-shek, and that guy was absolutely a true believer... in radical conservatism, rule by the ultra-rich and somehow also Georgism??? Either way current or future tyrants craft their ideologies at least in part to justify their rule, making them essentially rationalizations, in which case yeah mass murdering dictators had ways to rationalize their atrocities. It's impossible not to kill thousands or millions of people and not feel something about it; that's just not how people are built.
