I personally have no real problem with seeing a more realistic view on combat, but I don't want to see it just to see it. That to me is the hard line to draw.
At the risk of sounding like the idiots who blame television for moral decay, I do believe we're witnessing a true desensitization that makes this sort of violence simply normal to young people. There's a whole genre of television now devoted to watching people get seriously hurt on home video. Not a nerf ball to the nuts like the old days, but serious and lasting injury. The worse the better.
Hell, we don't even think anything of a movie that shows Superman's bastard son killing a guy.
We used to laugh when the A-Team made a point of showing the villains crawling out of every wrecked car, no matter how well they'd been blown up.
Maybe I'm just old now, but I'd rather have that in my insubstantial entertainment (and that is what we're talking about here) than this other extreme.
Sorry to be rambling. There are coherent thoughts in here somewhere. Rough day.
The Punisher Archie crossover gives this question a resounding yes.
Actually, Archie started as a backup feature to a Superhero comic called Pep. He eventually took it over.
