The eyes of a murderer (sanpaku eyes)

Is there a correlation between types of eyes connected to psychologically fucked up people?

Not only do I have really good instincts but a lot of times I can tell if someone is a bad person or not just by their eyes. I’ve never been wrong about someone even if it takes a minute to see their true character.

I’ve noticed with these people (a couple abusers, alcoholics, etc. in my life) that they’re eyes are all the type where you can see the white part of their eyes under the retina which is called sanpaku eyes

This isn’t true for every murderer, robber, rapist, abuser etc. but I’ve noticed with people in my life or people in my area, that this is very common, but I can’t find any studies on it

Also if you have these eyes please don’t be offended!! I don’t mean it offensively I’m just curious if anyone has read any studies on it because I can’t find any
