The Deranged Hit Man
It was formerly believed that the perfect assassin is one under the influence of hypnotism - someone who will be intensely focused on the task, every obstacle trampled upon; someone who will be so sure to get the job done efficiently and cleanly; a lean, mean killing machine. Snap out of it! You may have been watching too many movies and television shows.
As stated, no amount of hypnotism can force anybody to act against his instincts or his moral principles. Yes, you may not help but chuckle like a chicken when, for example, you were chosen as a participant in a hypnotism show. But you may opt not to pull that trigger given that one evil hypnotist tells you to do so. When someone mentions a suggestion as serious as this, something in your mind clicks off automatically and lets you decide rationally. Like when youre tipsy, you may sing My Way without inhibitions and with all the vocal calisthenics you could muster; but you are still aware and you can cut off the song (and probably release your audience from further discomfort) any moment you want to.
One theory on the assassination of Robert F. Kennedy was that the accused did the act because he was hypnotized. It was said that the assassin showed behavior typical of a hypnotized individual. Witnesses said he moved like a robot during the time he shot RFK. Tests showed that he is a highly suggestible, easily hypnotic subject. Still nothing of these was acknowledged, or even presented to the court.
