Everyone has to start somewhere. It's not as if a young boy from Tikrit woke up one day and decided he would be known as "the Butcher of Baghdad." It's far more likely such a boy would just become a butcher. (And for the record, Saddam Hussein was trained to be a lawyer.)
Also he was apparently a god-damned hipster 70 years before it was a thing.
The estimated number of people killed by Stalin's regime and its policies range between three and sixty million Soviet citizens, with the higher victim estimates being more common among experts.
