And when it goes wrong the practitioner will lie in your medical records to cover it up. When it goes even more wrong and the person is dead they'll just say "s(he) had serious issues". Having said that, I've seen it do wonders for some people.

Not sure if you're religious it not, but let me phase it like that. God put you on Earth to be you and do it your way. In an evolutionary context, it's a random process where the value of an individual can only be determined in hindsight after you're gone. Hence you need to be you and leave judgement to the ages. If you're at all concerned about that, you're a long way from being cluster B or dark triad, so don't sweat it.
