Very honestly - I’ve still not read the book entirely and I have started because I felt some feeling of guilt myself for being a Russian living outside Russia. I think that’s actually exactly what Jaspers, along with his students (the book is basically a dialectic lecture written down with results of work of his class from one semester), was trying to figure out. So I am not the best person to lecture you about that.
From as far as I have read these distinctions are exactly what allow people to talk about guilt, responsibility, trauma, the past, etc, without judging everyone by the same standards. Like, a criminal is judged by the court who defines for a crime they committed. A politician who took part in ordering crimes will be judged by the victor of a war. A soldier (just like a secretary) will be judged in dialogue with others and by his conscience for their individual actions, even if they were following orders. And a normal person who looked away or didn’t actively do their best to stop the atrocities that happen in the world, well, this person’s metaphysical guilt can basically only be judged by a metaphysical instance itself, be it God or another undefined transcendence. Basically all of us bear the latter.
They are very distinct and do not have the same repercussions. It is without doubt that political leaders have a much different, much more facetted responsibility for crimes committed. And we should focus on that. But this does not clean the people who followed their orders from all guilt, and their responsibility and crimes (against humanity) will be judged, just in a different way.
Edit: I’ve added a better phrased summary in my original comment above, since I have realized that translating German political philosophy isn’t my strength exactly.
Again - there is and must be a distinction between the blame, responsibility and guilt of an 18 year old uneducated soldier, nurse etc and a political leader. But this does not automatically absolve the former from all responsibility and guilt. You should and hopefully do focus on the latter’s guilt and responsibility, as it is much larger than the others’. Focussing on the people who follow orders is not what I would advertise for and this isn’t the intent, it is actually the exact opposite. By differentiating different aspects and kinds of guilt you have tools and language at hand to talk about it without putting everyone in the same boat.
It is not a black and white issue. Everyone got blood on their hands - you and me included - just in different amounts, in different ways.
