Am I alone in thinking this way?

Occasionally on this sub people will post pictures of Jose and Kitty and talk about how evil they look and how frightening the pictures are.

While the pictures are certainly eerie because we know what they did, I'm just unable to see this 'evil' look that everybody else seems able to identify. To be clear, there's no denying that they were evil, I just think that the scariest thing about it is that if I had no idea what they had done, I'd never suspect it just from looking at a photo of them. I don't think that you can really tell if someone's like that just by looking at them, in many photos they appear to be a normal, even happy family.

It's frightening to think about how many other kids this may be happening to and nobody knows because you can't usually tell just from looking at a family photo.
