If your skin is well soaked with salt water, 12V can absolutely kill you.
I seem to recall reading that one guy killed himself with a 6 V battery: he wanted to know what the resistance of the body (sans skin!) is, so put a needle into each of his hands. The plan was to measure resistance/current. The current killed him.
Plenty of people got killed by 48 V or thereabouts (electric welder). I have seen some images, gruesome.
