10. Stalin wanted to create a half-human, half-ape hybrid
This might be one of the most exciting and surprising things that you have ever heard about Stalin. There aren’t confirmed sources that can say that it is completely true, but it could be if we consider that he had a mental illness.
He ordered to Russian scientists to create a super warrior that would help him win every battle. Those warriors would be half-human and half-ape, they would have greater strength compared with a man, but they would also have underdeveloped brain. He considered that this would be necessary because they would be easier to control and to manipulate.
