If you are saying that the German army behaved badly because they killed civilians then I'd have to say you must be blind to the fact that in "modern'" war, Civilians ARE targets. The Americans and the British killed way more "innocents" than the germans killed of there "innocents" Spare me the "we did it cause they did it" aurgument, before any war ends civilians ALWAYS become legitimate targets.
NOTE: I am not endorsing the practice, merely stateing the obvious, Ethnic cleansing is a whole different subject, but as i said before, it has, is, and will be a reality for longer than I will live, it is going on today as we speak. While the Nazi were one of the best (not the best, I believe the Soviets topped them) at the practice, there's factions out there today that promise even greater slaughter in the name of any number of causes.
