Sans' left eye blinks when he attacks.

Undyne the Undying's left eye shoots lasers.

Mettaton EX's left eye is not being covered by his hair.

Mettaton NEO's left eye is not damaged.

Your FIGHT command is always on the left side.

So...

Left = violence.

Right = peace.

Because peace is the RIGHT thing to do.
