It's difficult to differentiate between "government" and "business", particularly where the two entities are strongly interrelated, as with both the Nazi and Soviet states.
You've omitted the case of Britain, who killed off a quarter the population of a country, largely through business interests:
Estimates of deaths in the business-operated slave trade run as high as 60 million, at a time when the total global population was 500m -- 1 billion (1/16th to 1/8 of today's population, very roughly 1/6 to 1/2 that of the WWI--WWII period). Recordkeeping was not especialy precise, as contrasted to the IBM-tallied slaughter of Jews by Nazi Germany.

Discussions of who's to blame and fingering "government" gloss over far too much to be especially meaningful except in ideological debate.
