Its not like it was a long dead corpse, fresh killed is probably not too bad as long as the bowels don’t release too much fluid.
I mean, I wouldn’t mind it that much, probably would be the quietist flight and I get to brag forever about the best passenger to fly next to, the dead body.
Yeah, it probably wouldn't release more than a quart or so of bodily fluids and fecal matter into the cabin.
Corpses have absolutely no control over their bladders and bowels, so buckle up and enjoy the ride!
