I think it's worth noting that the armed forces and the Nazi party itself were not in lock step for the duration of the 3rd Reich. While the SS answered more or less directly to the Nazi party there were certainly individuals throughout the leadership of the armed forces that did not like their resources being used to carry out genocide and or help the SS because they had little interest in that, they wanted to fight a real war. A lot of the leadership of the armed forces resented the fact that the Nazi party has usurped some of their power so they weren't too keen on bending over backwards to further the goals of their unspoken political opponents. Also have to remember that until they got the death camp system up and running most executions were done by firing squad. Doing this to civilians at large scale is kind of a shitty task so there's going to be really little enthusiasm for it from the lower officers and the grunts who will generally drag their feet and stall.
