A good though to have in ones mind when thinking about this topics is that you will probably be seen as someone horrible and barbaric with evil-morals by future standards.

Historical materialism perfectly answers your question. Quote from On Dialectical and Historical Materialism by J.V. Stalin:

"It is easy to understand how immensely important is the extension of the principles of the dialectical method to the study of social life and the history of society, and how immensely important is the application of these principles to the history of society and to the practical activities of the party of the proletariat.

If there are no isolated phenomena in the world, if all phenomena are interconnected and interdependent, then it is clear that every social system and every social movement in history must be evaluated not from the standpoint of "eternal justice" or some other preconceived idea, as is not infrequently done by historians, but from the standpoint of the conditions which gave rise to that system or that social movement and with which they are connected.

The slave system would be senseless, stupid and unnatural under modern conditions. But under the conditions of a disintegrating primitive communal system, the slave system is a quite understandable and natural phenomenon, since it represents an advance on the primitive communal system

The demand for a bourgeois-democratic republic when tsardom and bourgeois society existed, as, let us say, in Russia in 1905, was a quite understandable, proper and revolutionary demand; for at that time a bourgeois republic would have meant a step forward. But now, under the conditions of the U.S.S.R., the demand for a bourgeois-democratic republic would be a senseless and counterrevolutionary demand; for a bourgeois republic would be a retrograde step compared with the Soviet republic.

Everything depends on the conditions, time and place.

It is clear that without such a historical approach to social phenomena, the existence and development of the science of history is impossible; for only such an approach saves the science of history from becoming a jumble of accidents and an agglomeration of most absurd mistakes"

Conversely why do we act horrified that someone in the past didn't act according to standards that only exist today and pressures that don't.

We all exist because of those people’s exploits.

That’s basically where the concept of glory begins.

How is simping them any different from calling them "basically Hitler from the past"? If you're talking with your feelings, what you are saying is by definition not-objective, like with simps, but also with haters. I doubt you or OP are any more informed on history than the average Lemmy rando. By starting with the desired conclusion, rather than with arguments, the discussion is already beginning on subjective terms.

same feeling as when people talk fondly of "the great roman empire".

Imagine it's 7500bce... Most humans are still hunter gatherers but in a few places people have started banding together to form cities. The world is savage, hard, and dangerous. Life is short and cheap, and just like chimpanzees today don't feel any moral qualms about murdering rival troop members, humans hadn't really evolved socially to the point of thinking of all humans as inherently "special" or worthy of life... Some could say we still haven't all evolved to this point.

In that context what we were left with was a bunch of sociopaths. And no wonder. Most people would be somewhat sociopathic if their siblings died in infancy or were carried off to be slaves or eaten by wolves, their parents were murdered in front of them, their village was slaughtered and burned, etc. So these city people, and soon the surrounding people's, saw sociopathic behavior as normal and even something to be worshipped. (Again, some of us still do)

Sociopaths don't hesitate to harm other people to increase their own power and wealth, even when they don't really need anything more to live comfortably. In a world where might makes right, this was a huge advantage and the most horrible and brutal sociopaths rose to become kings of their city states.

There is some evidence that hunter gatherers groups would occasionally get a sociopath among them, but more often than not that person would be shunned and banished from the family. It was only when cities became a thing that there were tons of people from many families, so even if you're family kicked you out, you could just find other sociopaths who had been kicked out, and together you could just kill anyone who denied you.

There's also the fact that as soon as people started settling down and using agriculture to create excess food, the hunter gatherers around them started trying to take that food because hey, free food. So then you need to start defending your food stores, and again sociopaths rise to the top because they are the most ruthless "defenders".

Those sociopathic traits continued in the ruling class throughout all of human pre history and history. Right down to today where people continue to worship the sociopaths like Musk, Trump, or even Hillary. It's a childish thought process of "my dad can beat up your dad", which makes me feel safer, even if sometimes my dad also beats me.

Edit: just to add that the only reason we can even have this conversation is because, for the first time in human history, large swaths of the human population HAVE socially evolved to the point of recognizing innate human value, and thus can also recognize sociopathic behavior

(side note: freefall is an awesome webcomic, you should read it!)

Who is "we"? Many of us go to lengths to point out how important historical figures had dark aspects to their lives. This actually makes history far more interesting and relevant.

Mentioning those three names isn't "glorifying" them any more than saying who was in charge of a country during a war was.
