i do agree here 100% that Koba was worse than Hitler , whats about you ? who of them was Worse ? A Brief History On June 11, 1937, Soviet dictator Joseph Stalin had 8 of his top army generals executed as part of The Great Purge. From 1934 to 1940 Stalin had vast numbers of government, party, and army officials murdered to satisfy his paranoid delusions that everyone was out to get him. This left his military in bad shape when war came, stripped of many of its most capable officers, but just another day for “The Man of Steel.” Stalin was a bad person indeed, and although Hitler is generally regarded as the most evil man in history, Uncle Joe gives him a run for his money. Who else do you think is as bad or worse than Hitler? Digging Deeper 10. The Great Purge, 1934-1940.
