There is room for a successful argument that mainstream comic book superheroes have never been heroes and have always been champions of the status quo. I get this argument and can even see its merit. This is not my argument however.
My argument is that once Miller’s Dark Knight stuff broke all sales records there has been a constant downward spiral of even this level of “heroism” and that post-Miller mainstream superheroes are today essentially just sociopathic costumed clowns.
I feel like this would have been more true had it been posted 20-30 years ago. But while there’s some sociopathic types in books today, it’s a relatively small portion of the total.
I’d be curious to see what books in particular you have in mind, maybe from those published in the last month or so. I suspect what you really mean isn’t sociopath, but non traditional-heroic-archetypes. Which I would agree with, protagonists these days tend to be more humanistic rather than god-like.
