I know. Disgusting... I will say this though, as a psychology major, mind control is theoretically impossible. Hypnotism, however, is not. But there's a catch; hypnotism isn't magic. It's actually quite lame compared to how the media portrays it. In order to be susceptible to hypnosis, you MUST be agreeable to the actions you are being told to do. For instance, you cannot be hypnotised to kill somebody unless you, yourself, are okay with doing so. Hypnotism is merely convincing somebody to do something they wouldn't normally do. This of course doesn't mean it can't be dangerous when used on particularly weak-minded or morally-ambiguous people. Subliminal messaging can be particularly harmful.
