Sexual deviants are very dangerous indeed. Look at how dangerous PR was and how his sexual deviancy escalated to murdering Libby Squire.
Sexual deviants cannot control their urges, and the factors in their life at a given time can decide how far they go. Indecent Exposure one day might become murder the next day if say an argument has taken place, or his urge for sexual gratification has built up to a point where he is going to take what he wants, whether he harms someone in the process or not. Sexual deviants often view women as objects rather than human beings, they are disposable to them and only good for one thing.
They are able to lead double lives and usually claim to have never considered harming their partner because they actually know them as a person and are usually unable to become aroused without some kind of Paraphilia involved. Which is why they hunt at night for unwilling victims. They want someone who is genuinely terrified to taunt and attack. They want to feel powerful and in control. For them even if their partner was willing to perform certain acts, roleplay consensual non consent etc eventually it will not be enough because they need an actual victim who is unsuspecting and unwilling.
It’s all about their sexual gratification, the element of having a woman completely powerless and honestly afraid for her life is what thrills these men and once they graduate from flashing in McDonald’s to physically attacking women there’s often no going back. All MOO.
