Yes it is by the people your talking about. Marshall Sylver tells you himself that he can not make anyone do anything that they really do not want to do. I don't think he said this but the Subconscious has it's own kind of Conscious when it comes to things like KILL SOMEONE KILL YOURSELF these are things that you just won't do under hypnosis unless your crazy already but who knows maybe someone could be persuaded to do these things while under hypnosis. i mean it worked in The Naked Gun Right? KILL THE QUEEN
Your basically putting your conscious to sleep,like you do every day when driving,watching TV,and during many other things throughout the day. you let your subconscious take control and your subconscious has no reasoning,it does what it's told.
