The Soviets were no better when...

Not to say which is right and which is wrong (maybe leave it to historical expert) but, at some point, including or even especially WW2, didn't all or even most sides, not just Soviets and/or Nazis, commit "bad deeds" and "atrocities" and that unlike movies like action movies or even war movies, there were no total simple divisions into "good guys" and "bad guys" categories and no one official errrr "happy end"?

P.S. Have to say that I myself am Russian and since I was born in 1986 you could say I am a child of the Soviet Union. I have to say though, whilst it is true that no Russian completely denies the bad things that Soviet regime was guilty of, the mass murdering regime of Stalin and whatnot, most of them, as far as their own families are concerned, still legitimately recognize the end result of WW2 and us the Soviet war veterans as heroes who did the right thing and generally stopped a massive Nazi catastrophe and are proud of their history there. But are they completely wrong? Or is it not that simple? Can we maybe separate heroism and war crimes or is it far too difficult? If its the latter, how and why did Soviets manage it and have proudly lived with it for so long? And yet how come elsewhere it became known but no IN Russia and USSR?
