As an artfag that has spent hundreds of hours looking at peoples faces and bodies and carefully replicating their features, I can say that 99% of us have asymmetric features to one degree or another.
This is just biological bilateral-symmetry developing and shifting as we grow from an embryo to an adult. Hiccups happen along the way that makes one ear lower than the other, Or one eye sit farther back in the socket than the other.
The nuance of our idiosyncratic asymmetry is what makes us recognizable individuals, and not mirror reflections of each other. In particular, I don't think catching unflattering photos of people's asymmetry reveals anything about their potential deviancy. Just go look in the mirror and look for what's off on your own face.
