Holocaust Question Hypothesis- How did some of Hitler's soldiers disagree with him and what did they do about it?

I chose this question because not a lot of people know or think of the opinions of the Nazi soldiers. They were just displayed as horrible people, but not a lot of people thought about putting themselves in their shoes.

The Nazi soldiers that didn't want to follow Hitler's ideals diffidently had an internal struggle between wanting to serve and following Hitler's orders. They wanted Germany to be victorious against the other European powers, but not through the way that Hitler was doing it. Some maybe didn't like murdering Jews to win the war while others didn't like their fascist government made by Hitler. Either way, they wanted to take him down in some form of way.

There were planned attacks against Hitler within his own army. One example of this is when Hitler was in a meeting, this was a bomb planted underneath the table that went off during the meeting. Hitler obviously survived, but with minor injuries. It was later known that a high ranked soldier did it.
