The Joys of Discovering the Roman Underground

St Clemente is great though, and not nearly as busy as other sites. Highly recommended. You can see three different buildings all on top of each other.
But now it's all forgotten and Roman Empire is almost adored.
UPDATE: I honestly don't know what tortures were worse, nazi ones or crucifixions with flayed back, practiced in Roman empire as punishment.
Italian fashists also used a lot of Roman symbolism, but it's understandable because history.
Back to your original point, I would argue plenty of tourism exists for both regimes, focused on what the regime was best known for.
The Romans were known for being an advanced for their time civilization that pioneered many innovations that are still in use today in similar forms. While other things like their tortures existed, it's not how they exist in our cultural consciousness.
People tour Nazi sites that are representative of their place in our cultural consciousness as well, e.g. Auschwitz. Things like the Autobahn are not toured in the same way by WWII aficionados, because that's not their place in the cultural consciousness.
The reality on the ground of "who was worse" is not really relevant, the overwhelming force is how they are remembered.
For example, by any modern ethical standards, an emperor like Marcus Aurelius, or his mentor Antoninus Pious would be considered slaving, war-making monsters, but in the context of Rome and most rulers of Rome's time, they were remarkable paragons of forbearance and ethical nuance, and given the context of their upbringing, this makes them remarkable leaders, not just something so simplistic as cruel war mongers.
By the implicit logic you use, we should disregard the vast majority of major figures, systems and philosophies that have ever existed because they lacked the magical foresight of first having also developed our exact modern ethics (which in any case are often broken today by many respected leaders).
Also, please, there's no comparing the truly deliberate monstrosity of the Nazis to the practices of the Romans. Rome never developed intentional industrial extermination of human lives as a deliberate state policy. The Nazis did, and worse still, did so despite millennia of philosophical moral development being available to guide them otherwise.
Uh, except perhaps for a few centuries worth of persecuting Christians, subjecting them to tortures and deliberately putting them to death by the thousands, creating a basis for the veneration of martyrs in the years to come? Except for that, Rome really didn't intentionally exterminate human lives, right?
The majority of states, historically and today, sporadically or sometimes intensely take human lives to some degree, but this is very different from something like the policy the Nazis applied of wholesale, mass industrialized genocide of entire ethnic/religious classifications of people in the shortest possible time. As quickly as possible exterminating men, women and children using industrial infrastructure, without consideration for anything except destroying them completely until they were gone from the world.
This (again, obviously) is qualitatively and quantitatively very different from the Romans persecuting and sometimes killing Christians across several centuries.
It's very hard to find any one really taking the past literally, as events which happened and could easily happen again. One imagines it's a symptom of how we're born and die: before our birth feels unreal to us unless we have some contact in our lifetimes with people who were alive before it.
This effect becomes more concerning when people try to take advise from glorified people of the past: every roman emporer was a genocidal tyrant, none should be immitated. But here we are.
Also, I had a few typos there in the comment (like letter case). AIs are typically consistent.
