I'm not a half-god!
I'm Mr. Brightside
True pain is real because even hardened heroes shed tears from it. Yes, there were some terrible tortures in the Middle Ages...
Yes. The only major drawback of pain is that it leaves unpleasant marks on the body. If I had a device that stimulated only the nerves without damaging them, I would use it every day. It is rare to feel pain in a civilized lifestyle, and that's a pity. It helps me feel alive. Of course, given the above, I cannot torture myself; why spoil the existing shell? It will still be useful.
