And bit of an error.
1. The USA, Britan, France, etc. allies were not in the Battle of Berlin. Only the Soviet Union. The other allies took control of predetermined areas of administration after the Russians conquered Berlin.
2. The Nazi's showed no mercy towards those of Slavic decent, to them, they were just one step above Jews and should be enslaved (even today there is a bit ethnic racism against them as they are considered intermingled with Mongols).
3. Soldiers in the Red Army would liberate their villages, homes, etc. as they moved towards Germany and discover, mass graves, villages completely wiped out, Jewish extermination camps, etc.
4. Some Soviet Generals did ask their troops not to mass murder, rape, etc. civilians, but were under no illusion they could stop it, too many wanted revenge, and what they did still didn't reach up to the level what the Nazi's did to them.
5. A lot of those Civilians in Berlin were armed as they were given orders to fight to the last man, woman and child...and a number did. Children were given anti tank grenades and told to hide until a Soviet tank came by, run, activate it under the tank and hide. Many Nazi's told them that they would shoot them if they abandoned their positions.
6. And finally, a lot of Nazi officers fled out of Germany using their influence and wealth. Others surrendered to the western allies, all the while knowing the slaughter their populace would go through due to the orders they gave them.
You can't use that comparison.
