That's not exactly true. I keep seeing this misinformed idea that Goblin was some minor figure until he sold a bridge to Gwen Stacy, but the truth is Green Goblin was always intended to be a major threat from the very start. The only rogue in the L-D era who consistently escapes justice and prison time, and who had a big buildup about his identity as planned by both Ditko and Lee. Mysterio, Scorpion, Kraven, Vulture, Chameleon, Dr. Octopus...yeah those can be described as "just another villain to Spider-Man" but Green Goblin was always more than that.
I agree with you about the other stuff. Obviously Zdarsky is bringing a sense of modern judgment to those stories. If you did a story like that today, you couldn't do what Peter did originally in the L-R era and let him go with Norman's sympathy being largely out of some kind of class biases that Stan Lee had (i.e. Norman being an upstanding citizen), he's a Dad (but clearly not a good one) and he can reform and be a better Dad to Harry (even if his amnesia gives him serious issues and prevents him from taking responsibility for his actions and so truly redeem himself). Today we know a lot about enabling, and the danger of not reporting or calling abusive or sick people to authorities or properly protecting the people around them from harm. I had big problems with Spider-Man 1 and the whole "Don't tell Harry" thing which is rooted in the L-R era and Peter's first decision to spare Norman from justice. I mean that was presented by Raimi as this earnest plea from Norm an about not wanting Harry to see him at his worst (which doesn't make sense since he was always a terrible parent to him), but what you forget is the whole bunch of people Norman murdered leading up to that. Including the people at the parade and those kids he likely traumatized for life at the bridge by his terrorist actions. In real-life, if Bin Laden or some school shooter or the Oklahoma bomber said, "Don't tell my son" do you think people will honor that? Why is Harry Osborn's precious feelings more important than justice to the victims of the Green Goblin? The entire emotional center of the trilogy is keyed on you buying that, and I never did, so to me Spider-Man 1 worked until the ending of that film and the later films are crippled by that direction in the story.
Bendis brought that issue in his miniseries The Pulse where Ben Urich called out Peter for not doing enough to bust Norman Osborn or stop him from his seasonal killing sprees. And that led to Norman going to jail for the first time in over 40 real-time years publication history. No other Marvel villain rivals that or any DC villain for that matter. Kingpin's been in jail (and out) Dr. Doom has been deposed time and again, and even jailed I think once (though it might have been a doombot), same with other villains. But Norman Osborn thanks to Peter not wanting to hurt that drug-addled loser Harry Osborn's feelings, never got to see the slammer until Luke, Jessica, the Bugle, made Spidey wise-up and sent Norman to the slammer.
The Cap and Vietnam is similar. Today the version of Captain America that everyone accepts and loves, the one Chris Evans plays is "loyal to nothing, general--except the Dream". That's his character. But obviously the brand of Captain America is different. So if you put Steve Rogers and have him behave in character in Vietnam, that's what he would do. This article talks about that. (
