He did but not nearly as much as Stalin.

Equating soviet style communism and fascism completely ignores the base. Yes the structure of the government is similar but in fascism the underlying economic system is still capitalistic and market based, while in Soviet style communism it is nationalized and planned. It also ignores ideology, fascism is about asserting national and racial supremacy to the detriment of inferior races, communism is about seizing the means of production from the bourgeoisie and giving control to the proletariat. Even if the government structure is similar, the policies those governments enact are wildly different. Thats like saying reddit and lemmy are the same because they both work on up voted content percolating up.
