A stupid question about fried eggs

So this morning I fried bacon before my eggs, I guess for the first time ever when I have cooked. I didn’t take any of the grease out before cooking my eggs and because of that my eggs basically instantly cooked.

I typically cook my eggs with butter at a medium/high heat. As such my fried eggs always ended up more like scrambled eggs than a fry. Do people normally fill their pans with oil/grease to fry their eggs like I did today? I Had about a quarter of an inch(1cm) of grease in my pan.
