the fucking nazis were literally racist against slavic people, they did not take prisoners during their invasions, they sent them to death camps. to suggest that the soviets and the nazis were allies is patently absurd, their ideologies are diametrically opposed and you can do literally any cursory research to confirm the opinions of the people involved. literally read anything the nazis wrote about the soviets at the time, or anything the soviets wrote about the nazis. other users have already provided the context for those agreements, which you ignore. The soviets had tried to establish treaties with the allies before the molotov-ribbentrop pact, which they refused. it was an act of desperation to give the USSR time to establish military production factories and supply lines before the war. to spin that into an alliance is simply irresponsible historiography.
