my theory on the left eye thingy:
we all know our right brain and left brain cross over in their wiring,,,, God said something about if you you see such and such thru your right eye, you should rip it out…??? which could mean whatever it is they see thru their right eye, comes from the left therefore the black eye could serve as 'constant reminder which eye to see out of or which way to look at the world
Could it be 'punishment' when these people start to think about joining the human race again. I believe the 'right eye' 'sees' the good v evil sides of the brain
kapish? 😶🤷♀️
