What happen to blind people? U can't see their eyes, does that means they have no souls?
And not all normal people with good, healthy visions have souls. They can be cruel and evil. So I guess these people have the dark souls or soul-less.
People always say, to know the truth from someone, look them in the eyes. My questions are would you get the truth by looking into someone's eyes? and how do you know that person doesn't deceive you? don't eyes ever lie?
