i think it’s a sign of how (thankfully) far removed we are from that kind of violence that achilles’ dragging of hector’s corpse is so often framed mostly as an act of extreme disrespect, or only some brutal show of triumph. personally i think that’s underselling both achilles’ intention and what the trojans must be thinking as they watch it happen.
hector’s corpse is divinely protected so it can’t be damaged by the greeks after death; all that effectively happens in the iliad is that his body gets dirty. but under normal circumstances (and i’m not gonna impose realism on mythology, but the iliad is famously detailed when it comes to bodily trauma), the physical reality of dragging a corpse along stony ground for miles would be severe disfigurement and dismemberment. first the skin would wear off, then soft tissues, then extremities would start to detach. i think the iliad’s original audience would be aware of that as an intended outcome.
achilles (who doesn’t yet know that hector’s body has been granted divine stasis) doesn’t just want to parade his enemy’s corpse, he wants to tear it apart (“i only wish that this fury inside my heart would drive me to carve you to pieces and eat your flesh raw…”), he wants it to not resemble a human anymore. he wants hector’s blood and flesh to circle the city of troy. he wants to make it impossible for hector’s family to gather the pieces of him to cremate and that way hector’s spirit won’t find passage into the underworld. that’s what the gods are preventing from happening, they’re not just keeping the corpse pretty for priam to pick up later.
