It's an inherent logical conclusion from not only Leninist theory (...)

It's not at all. What's your justification for this reasoning?

Lenin betrayed what was initially a very anarchist and spontaenous in nature revolution but Lenin just used it to launch his state bureaucracy in power and then leading to the brutal suppression of working people immediately after the "revolution."

How was the establishment of the bourgeois Provisional Government anarchist in nature? Also spontaneity manifests itself as the politics of reaction — trade unionism. We have to divert energy towards building a working class revolution rather than demanding concessions whilst remaining subordinate to bourgeois rule.

Also how did Lenin use the Russian Revolution to 'launch his state bureaucracy' when the Bolsheviks' whole aim was to hand control to the soviets? That aside when you talk of 'brutal suppression' immediately after the revolution I think you're forgetting to mention that a civil war broke out and 14 armies including the US and UK invaded to oust the Bolshevik government.
