I don’t think this case would be highly unique, I am sure there is more then one SP that has been or is involved in something less then morally correct. I have been asked before if these skills are so dangerous why are people being taught them?
To paraphrase the link, it’s all about ethics. You could make the same argument about martial arts ( This was relevant at the time of the conversation ) . Anyone can walk up to you and lay one right in your face, so what do you do? Well you can try to avoid those types of people but sometimes that is not possible. Or you can learn how to defend yourself, also the bad guys can do that too. Either way there is still going to be a jerk that will punch you in the face, and it’s all about passing along an excellent moral compass to those you can.
