Depends on the setting. I've been in campaigns where news of our party arriving induced hiding in barns and such. Violence in comics has a long history (Sergeant Rock comes to mind, The Haunted Tank) and every super hero in the Marvel and DC universes. FWIW Belkar's violence seems to be comic relief, in the main ~ making fun of murderhobos and munchkins. Folks who don't play D&D may not get the joke. True with a lot of art.
And sometimes, a banana is just a banana. (Dan Akroyd, SNL, in a parody of Sigmund Freud)Sometimes a goblin is just a goblin and if the author wanted them to represent humans, they could've just as easily used a different group of humans.
