Except in those days they were considered cheap entertainment and they certainly didn’t dominate cultural output the way they do now. There was also a difference of treatment. The ubermenschen is not just about explicit super heroes, it’s more about the shift toward heroes with a destiny so manifest, and plot armor so thick, that they are morally justified in doing anything. The John Wick style “fuck you i’ll shoot up a night club cause some guy shanked my dog” which is written to feel entirely justified to the audience. And he’s right cause he wins in the end, just like the 80s action guy who’s totally justified in crashing dozens of cars during rush hour cause he kills the one bad guy in the end. It’s pretty distinct from comics culture which was actually pretty moralistic, at least that’s how i understand it.
