There seems to be a lot of distortion of Marxism (along with other things ) on this site so Id think we have to do into a bit of detail on what a deformed workers state is and what state capitalism is.
Well on this idea of a deformed workers state Lenin criticized his own government saying this-
Our state apparatus is so deplorable, not to say wretched, that we must first think very carefully how to combat its defects, bearing in mind that these defects are rooted in the past, which, although it has been overthrown, has not yet been overcome, not yet reached the stage of a culture that has receded into the past." (Works, vol. 33, page 487)
This was not the only time he spoke like this
"At present the State Bank is a bureaucratic power game. There is the truth for you, if you want to hear not the sweet communist-official lies (with which everyone feeds you as a high mandarin), but the truth. And if you do not want to look at this truth with open eyes, through all the communist lying, you are a man who has perished in the prime of life in a swamp of official lying. Now that is an unpleasant truth, but it is the truth." (Works, vol. 36, page 567)
"The more such work is done, the deeper we go into living practice, distracting the attention of both ourselves and our readers from the stinking bureaucratic and stinking intellectual Moscow (and, in general, Soviet bourgeois) atmospheres, the greater will be our success in improving both our press and all our constructive work." (Works, vol. 36, page 579)
"If we take Moscow, with its 4,700 Communists in responsible positions, and if we take the huge bureaucratic machine, that gigantic heap, we must ask: who is directing whom? I doubt very much whether it can be truthfully said that the Communists are directing that heap. To tell the truth, they are not directing, they are being directed." (Works, vol. 33, page 288)
"But we have not finished building even the foundations of socialist economy and the hostile power of moribund capitalism can still deprive us of that. We must clearly appreciate this and frankly admit it; for there is nothing more dangerous than illusions (and vertigo, particularly at high altitudes). And there is absolutely nothing terrible, nothing that should give legitimate grounds for the slightest despondency, in admitting this bitter truth; we have always urged and reiterated the elementary truth of Marxism - that the joint efforts of the workers of several advanced countries are needed for the victory of socialism." (Works, vol. 33, page 206)
So Lenin felt that the USSR was not "socialism", not "communism", but a workers' state and Lenin was not afraid to add "with bureaucratic distortions". So he knew there was going to be a fight on to save the USSR from falling into bureaucratic capitalism or state capitalism. He even actively started to fight this until the time of his shooting because of this his health deteriorated till his death in 1924. so it was deformed because it had the seed of a new ruling class of which the new bureaucracy was to become and turn Russia into state capitalism.
Now state capitalism is where you have a new ruling class the state bureaucrats who control the means of production and gather revenue through extracting surplus value from the workers efforts, Thus making a new under class which are alienated from the means of production and the ruling class. Stalin completed this turning the people to nothing more then surfs attached to the state for labour.
