It was on one of his motorcycle journeys that Che witness the exploitation of workers and farmers as well as intense poverty that provoked him to make a change. Admiring Guatemala's president Jacobo Arbenz Guzmán redistributing land to the peasants, Che met the Castro brothers, Fidel and Raúl in Mexico in 1955. Che helped Fidel overthrow the Batista government in Cuba and set up a communist government that came with a free healthcare system. Che was peculiarly enough not involved in the healthcare despite his qualifications and was in charge of the La Cabaña Fortress prison where during his time, he had 144 people executed under his extra judicial orders. Later on, Che was appointed president of the national bank of Cuba and helped with Cuba's trade relations by shifting from the United States to the Soviet Union (Russia and 14 other states and he also improved literacy rates in Cuba up to a 96% rate.

The one group Che hated wasn't a minority but rather an organization, the Central Intelligence Agencey (CIA for short). The CIA backed a group that forced the man he liked (in an idolizing way) Arbenez to step down and Che almost immediately saw the US as an imperialist power. The CIA (who were also the subject of a parody song by Weird Al Yankovic) hired advisers to aid the Bolivian army to kill Che who was trying to help the Bolivian civilians topple their government in 1967. Che was captured on 8 October 1967 and was killed the next day.
