We did similar atrocities, war brings out the worst in people, not the best. I served with many of the WW II guys, they told me that a lot of bad s#!t happened in WW II and Korea. As the population grows and moves beyond the WW II years, that village may end up as a condo complex. All that is needed is for someone to offer enough $$$$ to the politicians to allow the purchase and make the change. Politicians can change history, and they often do.
Well, generally not.
It's one thing if individuals or units commit atrocities vs. the institutionalized atrocities of the Nazis.
Individual US units have committed atrocities but there was no general policy of encouraging or even requiring such atrocities in US units as there was in the Waffen SS and Wehrmacht.
Limited reprisal actions were still allowed under the laws of war before WWII, but the Germans committed atrocities far beyond anything remotely sanctioned. In Poland, for instance, I think they started out with 10 Poles killed for every German killed by the Home Army. By 1944 I think it was up to 100. It was so bad that in a few places the Home Army was able to strike deals where they would forego killing German soldiers off duty in the streets if the Germans would forego the reprisals.
