@jackstock I have seen some BAD abreactions in my time, unfortunately psychological damage from hypnosis is totally possible. I have had to clean up after it and it's not pretty. The typical thing is an inept hypnotist who is trying to do something way beyond his skill, and / or a subject who failed to disclose a preexisting mental illness or piece of prior hypnosis that was incompatible.
Could it be done deliberately? Probably. You would need a very skilled hypnotist with an intimate knowledge of that particular subjects psychology and a subject who was vulnerable to such a thing. For it to stick the resulting insanity would have to be ecological for the subject, but there are many cases where that could be so; most notably the original poster's case of wanting to be insane. The hidden observer isn't going to protect a subject from a self chosen goal state.
My favorite example is Sgt Shaw (the brainwashed assassin in Manchurian Candidate): Ordinarily you couldn't hypnotize someone into being a killer, but Raymond Shaw as portrayed in the novel is an angry guy who subconsciously constantly wants to kill everyone. A subject who had the Sgt. Shaw ecology would fail to resist the suggestions to kill that 99% of subjects successfully resist precisely because it satisfies a preexisting subconscious need, and he only succeeds in killing someone other than the intended target [b]because[/b] it's more ecological for him to kill his abusive mother (the true source of his rage) than it is to follow orders and kill yet another stranger.
