It's entirely possible, but hard to say for sure. The past\current crop of the world's communist parties are a poor reflection of it as a system of government, seeing as none were really communist in the strictest sense of the world.
And as well, it's pretty damn hard to find any country in the world, regardless of the system of government, that hasn't committed some violation of the rights of its people.
Agreed, every country in existence has done theses things at one point or another
