Low punishment? The guy loses his dick, what could be worse than that? Not only can he not rape anyone else, but he has to pee out of a straw! What could be worse for a man hyped on sexual ego?
This is my thinking, the guy who does it with the minor, that's rape and falls under rape. Bad enough for him. The guy with the video camera made it possible that the act could be spread and seen for thousands of pedos to see. So he made it possible for someone to see it and get off sexually to it, and for that enabled thousands of other normal people to possibly become pedos themselves one day when downloading random porn. And the embarrassment factor for the raped is huge, because once something is on the internet it's there for good most of the time.
And as said, "extra punishment" could add in on the rapist. For instance, "extra punishment" could involve a man who brutally raped multiple boys, could have a stick shoved so far up his ass it comes out of his mouth. Just so he knows the feeling.
Of course, has I've been told countless times, that's just my "perverted over-the-edge" thinking. Take it or leave it.
