I see where you're coming from. They do look pretty mean but those are still considered angel eyes. They aren't staggered and angled like the set of pics below yours. The angel eyes have more of a halo look to them where the demon eyes are more like half circles that look like mean eyes looking at you.

 

When the angel eyes came out they were called halos, like an angel, so when someone made the red ones they called them demon. I guess the definition has changed. I recall the demon eyes being on a gray m3, but I can't find the pictures now.
