I'm not sure if you know how real hypnotism works. Its not just swinging a pocket watch back and forth, and the subject turning into a thrall. The way it works is that the hypnotist puts the subject into a more relaxed state. If the subject doesn't want to relax, then it won't work. In real life hypnosis is used mostly for therapeutic purposes, allowing the subject to talk, and remember things without any other influnce besides the hypnotist. It's almost like meditation, but with a guide, and suggestions to help find specific things. Once again, no one can be hypnotized if they don't want it, and they don't become mindless thralls.
