Lenin wrote ‘State and Revolution’ in 1917, while he was hiding from the Russian secret police. The book describes the inherent nature of the State as a tool for class oppression, a creation born of one social class’s desire to control all other social classes. Drawing on detailed quotes from Karl Marx and Friedrick Engels, Lenin lays down a Marxist view of the state, describes how a working-class revolution will overthrow it, and goes further in showing how social democracy is not enough—even in democratic republics such as those enjoyed by many western countries today, the ruling class is still in control of society, and will never relinquish power. According to Lenin, a Communist revolution is the only remedy for class struggle. This work by Lenin is important to communist thinking and the Marxist concept of the state which is clearly and concisely expressed in this book. Without doubt this is a classic work and will give the reader important concepts in the theory of Marxist-Leninism.
Though clearly what happened in the USSR in the 20s was something different from what he wrote. What you saw in Russia in that period was a response to an ongoing civil war, followed by the rise of Stalin.. who, yes, really did believe in brutal authoritarianism.
All these Stalinist states (and I would classify China this way too) will pay lip service to Leninism as a way to seek ideological legitimacy. But their "official" readings of Marx and Lenin are very... creative... shall we say.
But it's 1:30am and I should no be getting into this argument.
The core distinction between Marxists and many forms of Anarchists, as early as during the dispute in the First International between Bukharin and Marx, was their view not on the long term dismantling of the state - where they agreed - but the role of the state in the transition from capitalism to socialism, where the anarchists wanted the state dismantled immediately, while Marx argued the state could serve a role in a transition, itself becoming a tool to execute the changes necessary to change society.
In his works on the Paris Commune he explicitly criticised the Communards for failing to take the next step and destroy the bourgeois state. While that could certainly have been replaced with a proposed federation, a key distinction was that he celebrated the bottom up delegation of authority, which is hardly compatible with "command and control" if any part can withdraw.
As such, libertarian Marxism directly opposed to the very existence of a state became a thing, based in large part on his writings on the Paris Commune.
Capital is a doorstop, but I have heard that past chapter one which talks about the labor theory of value, the reading is much more breezy.
However, while some of these books are dense, even rural peasants have been able to read and metabolize these books, so don't despair!
You want actual evidence of what actual major socialist thinkers thought of the state during the time when socialism was most relevant, read Marx's 18th Brumaire or read Lenin's State and Revolution and come to your own conclusions.
