I tend to agree with Rosebud .. waste not, want not. I'd cut away the darkened layer plus an extra half-inch just to be safe. Then taste. If the "stinky cheese" taste/smell has gone through the whole block .. toss it.
The thing with rancid fat/oil is that "rancid" means the fatty acids have oxidized. Oxidized fats (and also oxidized cholesterol) are bad news for health as well as your nose. In the case of butter, the main fatty acid .. butyric acid or butyrate .. will develop the tell-tale stinky cheese odour when it becomes oxidized. So even if it looks okay, if it smells cheesy .. it's done for.
