You are surprisingly right. I know people who served in IDF and would prefer to have nothing in common with those criminals. Generalizing to them would be wrong. It is not voluntary service, different people are required to serve. But people aside, is IDF as institution rotten? It is not generalization to say „yes“, when such things happen. An institution is an entity with the agency to prevent such things and not only did it fail, it covered up. Is Israeli government complicit? Hell, yes, same reason.

There were people in the German army (Wehrmacht) who wanted to have nothing in common with those criminals. Some even tried to kill Hitler and get rid of the regime.

Not the majority though, else the wehrmacht would have done less war crimes.

I think this depends on whether you draw the boundary at "refuses to do X even when killed for it" or "wouldn't have done X on their own".

Most soldiers who disagreed with the Nazi left the Wehrmacht by 38 (or were pushed out, or were beaten and restrained for month in 'black site', often disaffected warehouses where socialists and Communist were 'retrained', basically proto-concentration camps).

In 42-43 some were reintegrated forcefully, and those I agree do not bear responsibility for the Wehrmacht war crimes.

My grandmother had a lot of stories about the Wehrmacht and was very disappointed that they were basically whitewashed from their pedophilic rapes, public executions and other group punishment.

IDF is an army of Israel, not some unknown militant group.

Israel is a state, as they call "democratic", which elected officials who have control to stop these crimes, but not stopping deliberately.
