In January 1957, as his diary from the Sierra Maestra indicates, Guevara shot Eutimio Guerra because he suspected him of passing on information: “I ended the problem with a .32 caliber pistol, in the right side of his brain.... His belongings were now mine.” Later he shot Aristidio, a peasant who expressed the desire to leave whenever the rebels moved on. While he wondered whether this particular victim “was really guilty enough to deserve death,” he had no qualms about ordering the death of Echevarría, a brother of one of his comrades, because of unspecified crimes: “He had to pay the price.” At other times he would simulate executions without carrying them out, as a method of psychological torture.
