Gao Xiaosong said that the Soviet Union was dark, cruel, and had almost no bright spots.

It always seems to make no sense, because the more oppressive some things are, the more they will retreat (refer to a certain country). Does it mean that the Soviet Union has some valuable qualities that I have not seen?
