It's true that the original army command wasn't a big Hitler fan, but it was still an enabler. Like all the aristocracy who looked down on Hitler and thought they could use (and contain) him.

The thing with the German army ("Wehrmacht") is that for decades Germans told themselves that sure, SA/SS were evil and did horrible things, but the Wehrmacht was "clean", so granddaddy never did anything wrong, he was only defending his country.

Then in the nineties, https://en.m.wikipedia.org/wiki/Wehrmachtsausstellung came along, showing how the common Wehrmacht committed its share of atrocities.

When I went there with school I actually had my grandmother calling me on the phone, in tears, telling me that her husband was no murderer.

This exhibition ripped apart a few lies we Germans had told ourselves about our honorable Wehrmacht.
