Che Guevara
In Guevara's private writings from this time (since released), he displays his growing criticism of the Soviet political economy, believing that the Soviets had "forgotten Marx". This led Guevara to denounce a range of Soviet practices including what he saw as their attempt to "air-brush the inherent violence of class struggle integral to the transition from capitalism to socialism", their "dangerous" policy of peaceful co-existence with the United States, their failure to push for a "change in consciousness" towards the idea of work, and their attempt to "liberalize" the socialist economy. Guevara wanted the complete elimination of money, interest, commodity production, the market economy, and "mercantile relationships": all conditions that the Soviets argued would only disappear when world communism was achieved. Disagreeing with this incrementalist approach, Guevara criticized the "Soviet Manual of Political Economy", correctly predicting that if USSR did not abolish the law of value (as Guevara desired), it would eventually return to capitalism.
Legacy of Che Guevara
Although to some Che is known as a hero — Nelson Mandela referred to him as: "An inspiration for every human being who loves freedom" — others view him as the spokesman of a failing ideology and a ruthless executioner who did not afford others a proper legal process. Critics point out that Che justified murdering people without knowing if they are fully guilty. They point out that in a May 18, 1962 speech Che said: "We executed many people by firing squad without knowing if they were fully guilty. At times, the Revolution cannot stop to conduct much investigation; it has the obligation to triumph."
