What you say is like a nice idea, but you have to remember that this is a business. These kinds of comics line the shelves, because they're the ones that sell. Of course, it could very well be that if we had more comics that were more moderate they would sell also, but nobody's willing to take the risk. On top of that, you also require an author that is interested in that - you can't just suck this stuff out of a pen to make money (although often this does happen, they tend to end up being less interesting though).
If the comic is printed out then somebody has to buy it. If the comics aren't bought enough then it just won't work. It doesn't matter whether our ideal society would have us have more moderate comics or not, because it seems that in reality that's not the case. Of course, you can always prove me wrong (and the comic industry) by creating your own comic that does adhere to the criteria you enjoy. You would probably be rather successful if people truly wanted it, because it seems like there is no competition for them. But it seems unlikely.
