The "bias"

Lets start with the Onion, war crimes all over, most of them coming from soldiers who have suffered terribly during the war; their families - dead, their friends - dead, friends' families - dead and raped.
So the Soviets soldiers go wild when they finally reach Germany, some start even earlier in Poland (you know what a man is like after not being with a woman for years). Hate has been growing in them since the first days of the war and now going all this wanted them to take revenge on the Germans, even if civillians weren't much involved, but it's not like they're gonna care about that.
Horrible war crimes, children raped (sometimes) but women were  almost always raped (even tho the number can be exaggerated, but this is a whole other mess that I dont want to get into right now)  . Also destruction of property on purpose and pillaging (those are also war crimes)
