I fear that...
Again it's another case of putting a stop to a "cause" of something, where when what happens in reality is most of the sick writings by the real sicko's are kept private until they are discovered in their hideout, along with a stew of human and vegs. But, becuase there are soooo many sickos, thousands per million apparently (situations like this require immediate statistics! Even if they are made up, it's all part of proving a point), since there are sooo many sickos then they need to arrest someone, otherwise it will be business as usual (usual as in it's ALWAYS been this way), they'll find the sicko when he/she messes up and gets caught, mostly becuase insanity is almost always careless, and most of the famous genius sickos only exist in dramatizations in film and in the "NEWS". And like most witch hunts, the people arrested, though not legitimate sickos on a sociopolitical level, will make the Gov look as though they are accomplishing something, kind of like a good number of "law breakers" today.
Now, back to reality, assuming that the Great Overmind exists that connects humanity to all life and inter-dimensional beings, then I would say yes, depraved thoughts may be disruptive to the overall health of the Overmind, and in response, it would be in the interest of those who share the mind to take out the sick minded. Lucky for us, the higher life forms seem to understand simple social changes can fix it all, otherwise I think a world wide Sodom-Gomorrah action would have taken place by now. Not to mention, the sick minded tend to be self destructive and take themselves out all the time either on purpose or thought slipping up and getting caught.
To real-reality, what has caused the widespread nature of the less than appropriate writings/fantasies/rages has a lot to do with extremely poor marketing strategies used by the media giants where money is more important than social consequences and precedents that they create. Back in the 80's a lot of the big US stars were always playing their TV persona's when they are in public (remember Pee-Wee Herman and what happened to him when people found out he was a human?), or even today with so many who are now adults STILL believe "professional wrestling" is real and not a huge extremely violent-like Cirque du Soleil. Seeing the face of some who sees the facts with digital rewind and slomo, from having seen it personally, it's like watching a kid find out Santa is not real (I used to have fun with that as a kid, but as I grew up I stopped resenting the kids for their stupidity and started resenting the parents instead, I could have been a professional sociopath, but thankfully I learned empathy early enough :P So now I'm just a sarcastic pretend-sociopath, Do unto others, blah blah and all that).
Honestly I think their should be an insane law against witch hunts, and the fanatics that stoke them, so that they would know what it is like to be a criminal for something as simple as a thought, idea, or belief.
Most of the sociopaths I know, or have read about, have been spoiled brats (not monetarily), who have been allowed to get away with anything they want becuase their doting parents are too stupid to see the signs of their kids careless actions. If they aren't spoiled, then usually they are left so isolated and alone socially they will decide on their insane ideas all on their own because of the lack of consequences. Consequences that, with the right amount of empathy, should be doled out by the perpetrators onto themselves, which shows another way in which society fails "us" (life forms that don't develop their own sense of empathy are usually killed by their fellow life forms, or banished form the pack). They have no respect at all for their fellow stupid humans, enjoy inflicting pain on others becuase they feel the person deserves it (usually it's mental pain), and they love playing with people's heads becuase they think they are the only ones that know how easy it is to do so (everybody is stupid, right? and yes, that does mean you too), and they have the advantage becuase in the fight against wrong thinking, the rest of us are not allowed to know how easy we are to fool. Hence, laws like this one leads to the prosecution of the innocent, and a free reign for the real psychopaths because they know that this is happening and probably can't believe their luck, becuase it keeps people looking away from trouble becuase they can't recognize it when they see it, becuase they are told to see it everywhere. Sounds almost like the stories from DR Congo and the Sudan, the angels who are sent in to save the innocent are really the demons, and the "demons" they are fighting are just trying to not die or be raped anymore. This kind of thing is happening all over the world in one way or another to most of us, and just shows that those who create the laws to protect us form the sickos are doing a horrible job becuase a lot of them ARE the worst of the sickos.
