Answer:
Stalin's rule was neither good or bad, it had some good aspects and some bad aspects.
Step-by-step explanation:
The positive aspects of Stalin's rule are mainly two: his economic policy was successful in the sense that he managed to finally industrialize the country, since at the time his rule started, the USSR was essentially an agrarian country.
The other positive aspect is that he led the Soviet resistance to Nazi Germany, and, at the cost of 25 million Soviet lives, managed to help in the defeat of Nazi Germany.
The negative aspects are also economic in nature, because his agricultural economic policy failed several times, and led to various episodes of famine, including the Holodomor.
The other negative aspect is in the field of civil liberties and civil rights. Stalin imprisoned people in the gulags, sent political opponets to execution, and even erased people from official records.
