You want to constantly feel like you're skinned alive? The only way the pain stops is if they wear the skin of another organism, and that only lasts for about a day, you'll feel like you've been degloved entirely for your entire fucking life, from the moment you've been born, skinstealers have their own skin but the pain is just a part of their biology to ensure survival.
I have killed a man before, you can find the body in Richmond, Virginia, you'll know it's there when you see the large red stone I used as the weapon on the dirt,
