Okay, don't get me wrong, I'm not saying Sableye can't look decent without pupils. Hell, sometimes it works extremely well—if you're TRYING to make it look creepy or derpy. What I'm saying is that when you try to give a Sableye any expression other than a creepy wide-eyed smile, it really doesn't work without the pupils. That is why I decided to start drawing them with pupils long ago, and the same goes for many other artists.

I'm just trying to remind us all of it/explain it in my own comedic way.
