Dresden before and after.

“The Germans are not human beings. If you have not killed at least one German a day, you have wasted that day. If you cannot kill your German with a bullet, kill him with your bayonet. [T]here is nothing more amusing for us than a heap of German corpses. Do not count days. Count only the number of Germans killed by you. Kill the German—that is your grandmother’s request. Kill the German—that is your child’s prayer. Kill the German—that is your motherland’s loud request. Do not miss. Do not let through. Kill. Kill, Red Army men, kill! No fascist is innocent, be he alive, be he as yet unborn.”
“Kill them all, men, old men, children and the women, after you have amused yourself with them! Kill. Nothing in Germany is guiltless, neither the living nor the yet unborn. Break the racial pride of the German women. Take her as your legitimate booty. Kill, you brave soldiers of the victorious Soviet Army.”
—Ilya Ehrenburg, Jewish Soviet propagandist
