1) They seen it in the past and can't get it out of their minds and it becomes a fetish.
2) They always want to see the murderer's point of view but don't actually want to commit the act itself. (a lot of guro fans say this, and it doesn sound credible)
3) It's like hate-art, used to direct their frustrations somewhere else.
I don't like guro either so the best thing to do is get the hell away from there as soon as possible, block the address using a password that's freakishly long, and get drunk just to try and forget what you saw.
I try and give these guys the benefit of the doubt that most of them are whackin to this stuff and that its mostly psychological stimulation as opposed to physical, but I know thats bullshit. One guy explained to me that his "appreciation" for guro is fantasizing about putting people he hates or stereotypes he hates into some of those pictures (sort of like those games on newgrounds only a little more f'd up). Another offered up an explanation as to him picturing himself being a superhero and swooping in and magically saving these girls (damsel in distress or whatever). One other guy admitted plainly to being fucked up and enjoying torture and whatnot, "Its like another form of bondage, only going a little further".
As long as it stays in the comics online, you can do whatever the fuck you want. Rest assured that there are no shortage of people willing to stop you from doing shit like this for real.
Okay, you know, I still had a little faith in the human race. Just a little optimism in the back of my mind.
But knowing that there are people who can actually beat off to this sick shit has effectively removed any hope I had.
I'm just going to sit here and wait for the impending apocalype, once God finds out about this site.
See, to me the whole RIPPING PEOPLE'S ORAFICES OPEN FOR SEXUAL PLEASURE is the disturbing part, but I guess I've come to terms with the whole pedophilia thing. Now I've got a whole new world to repress.
