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.
