What to do about magicians, who have powers that they acquired without the help of demons, and who can use those powers for good as well as for ill, is a tough call. Likewise with people who have superpowers that they've always had, and that they can't shed.
Imagine we discovered that there were telepaths living among us, people who could undetectably read our minds, in a way that we couldn't block. Or imagine that there were people who could undetectably control into our minds, in a way that we couldn't block. Would we be justified in locking them up, or even killing them?
