It wasn't limited because being a children's show allowed for a focus on elements that may not have been developed in an "adult" show. Likewise, the show wouldn't have been "limited" had it been an adult show. One it neither greater than the other. Your assumption that adult shows are somehow better than children's media is unsubstantiated.
That assumption thus makes me skeptical of what you mean by "rape". Because when tryhard edgelords like yourself say, "why is there no rape" what they mean is, "why is there no fan service where the hot female character gets railed?" This is the kind of rape you see in most Hollywood films, in cheap exploitation, in the latter seasons of Game of Thrones.
By contrast, works like Berserk or Irreversible have ubiquitous rape but it is portrayed far more accurately - as the expression of power. In the real world, it isn't just your hot waifu that gets fucked, it's ugly girls, old women, young men, boys, older men, etc. Look at the Rape of Nanking. Yes, you had the rape of young beautiful women, but you also had the rape of entire families. That's because rape isn't about sexual attractiveness, but control and domination.
So would Avatar have been improved by rape? Given the framework you, OP, and most Pedowood shills operate on, likely not. Could someone have used the Avatar-verse to deal with issues of sexual abuse? Sure. And it could have been intelligent and compelling. But that would have been unlikely.
And about your image - would the Fire Nation have normalised rape? I don't know much about the cultural practices of the countries the Fire Nation is derived from. Maybe their culture would have a strong taboo against it whereas one of the other four nations did not. Let's be creative, here.
TLDR: OP is probably a sexist creep if his concept of "darker" is "hot girl raped" and not some Battle of Suiyang shit. Why not ask if Avatar would be improved by Iroh eating some dude's face?
