Joseph Stalin - His policies led to the imprisonment, deportation, exile and execution of many of the Russian citizens. His policies that changed Russia from an agrarian society to an industrial power so disrupted the country's agriculture that it created the catastrophic Soviet famine of 1932-33. The campaign that resulted in the Great Purge saw the execution of hundreds of thousands. This included major figures in the Communist Party. I remember listening to reports of his death in 1953.
Stalin did not fight during the First World War. As a child he had been struck on two separate occasions by horse-drawn carriages, causing permanent damage to his left arm, and exempting him from the front. 1918.
