Not a firefighter, though I’m related to some and have had discussions about the morbid stuff with them.

From my end of things, I’ve been around burn victims, and close enough to a fire where someone was burned to death to have smelled what you’re asking about.

Like others have said, during a fire, the firefighters are going to be geared up, so they won’t smell it while it’s happening. The lingering smell isn’t as noticeable after because there’s just too many other smells present. That was true for me as a bystander, and my family have said the same.

But I can’t say it smells different in a way that I could sniff it on the wind and automatically know that it was a person, and not someone grilling. I might guess it was pork rather than beef, but I’d say that venison getting over cooked is closer than pork getting over cooked.

It just smells like burning meat. And it wasn’t even that strong at the fire I was present for. I would have guessed it was something in a freezer or fridge at the time.

The remains that time essentially smelled like burnt meat. Damn near all meat smells the same when burnt. Only thing I can think of that stands out is really oily fish. And even that isn’t so different it matters much because the burnt meat smell is still the dominant odor.

Raw human meat smells the same as raw animal meat usually. I’ve been wrist deep in wounds, infected or not, and I’ve processed freshly killed animals. Only time I could tell a difference between mammals is wild vs domesticated. A lot of game animals smell gamy, and domesticated rarely do, and won’t be as strong.

Imo, if you would have a problem with the smell of burnt human being so close to the smell of burnt animal, chances are that the smell of meat cooking would have already bothered you a little. It does bother some people. But I’ve never known anyone that eats meat suddenly give it up after smelling burnt human. I’ve heard of it, but never met anyone that said it.

Now, there’s a pretty damn common reaction to the immediacy of something like that. Like, don’t ask me to eat a rare steak right after I pack a wound, you dig? But a well done burger? Sure. That’s down to individual tolerances though, and mine is more that when I’m packing a wound, it’s usually in bad shape, likely infected or with necrotic tissue.

And the smell of rotting meat, human or not, will put a lot of people off their feed for a while.

So, I’d say that, overall, it’s less about the actual smell and more about how the individual copes with the knowledge that death and horror are everywhere. The more that kind of thing worries you, the more likely you are to see the connection between how much humans are just another kind of meat, and what we eat. The less it worries you, the less repulsion you’ll feel from similar foods.

It’s why, even when I’m trolling vegans, I ain’t mad at being vegan. They just have different set of associations between meat and where it comes from. Can’t be upset about that at all.
