Answer: After the events of Vladimir Lenin’s death Stalin began to take power. When Stalin went to Lenin’s funeral, Joseph Stalin would keep on referring to Lenin as, "the great Lenin," creating the illusion that he was more loyal to the soviets and Lenin, then his opponent Leon Trotsky.
However, in comparison to what Khrushchev had to say about Stalin, the two are completely different. Khrushchev was a very anti-Stalin leader, even spending most of his presidency trying to de-Stalinize the U.S.S.R. Khrushchev repeatedly referred to Stalin as a "cruel dictator." Khrushchev eventually spent the rest of his life while under KGB surveillance.
