From a strictly rational perspective, I believe that the greater damage is done to the boy rather than to anyone else.  While some view the kind of actions the kid is accused of as worse than murder and thus justify that the kid will have to register as a sex offender for the next 50-70 years, no rational analysis of the situation can lead to that conclusion.  In 50-70 years, the girls involved will likely barely remember the incidents.  If they do find such sex issues to gravely injure their lives, I propose that we as a society have failed them by teaching that non-lethal or non-mutilating (physically) events are so important or traumatic.  Our society is dysfunctional in many ways and this is one of the extremes.  Our life-long ostracism for less than murder is misguided.
