I'm not disagreeing. I'm just saying that there is no connection between personal character and the ability to develop that kind of power: it is entirely possible to have a "Darth Vader" of internal power, and many people are wary of the pursuit of power in any form.
George Ledyard gave an example of a guy who certainly misused his aikido power. Maybe aikido itself should never have been revealed to the public?
Many people think that any kind of martial arts training at all is motivated by the desire to make oneself a walking weapon. Would that be true?
