If they do that then the GP's rearing of them has failed already. If one hasn't managed to instill at least that minimum of sense into them by the time they're old enough to even contemplate that, then they'll just do it anyway, as soon as their parents unlock the shackles and let them out into the daylight on their 18th or 21st birthday.
Yeah, so what? How the fuck else are they supposed to grow up?
