The very next paragraph read as follows:
Before the dissolution of the Soviet Union and the archival revelations, some historians estimated that the numbers killed by Stalin's regime were 20 million or higher.[5][6][7] After the Soviet Union dissolved, evidence from the Soviet archives was declassified and researchers were allowed to study it. This contained official records of 799,455 executions (1921–1953),[8][9][10][11][12] around 1.5 to 1.7 million deaths in the Gulag,[13][14][15] some 390,000[16] deaths during the dekulakization forced resettlement, and up to 400,000 deaths of persons deported during the 1940s,[17] with a total of about 3.3 million officially recorded victims in these categories.[18] According to historian Stephen Wheatcroft, approximately 1 million of these deaths were "purposive" while the rest happened through neglect and irresponsibility.
You can't blame all the deaths on Nazis.
I just want to know if those excess deaths are part of the Marxist ideology or not. You say the USSR was a country following Marxist theory. At least 7 million people died either because they were killed by the state or died through negligence. Are all those deaths explained away by "The war caused their deaths" and "They deserved it anyways"? Were a significant number of them killed despite the USSR being marxist or because of it?
