I guess sooner or later this topic had to appear.I'm verry happy with myself, i like guro and i like living in society, so coming here and seeing guro-hentai is, for me, above actually living the fantasy.If you acctualy do it, you will acquire a state of fear/worry of being caught wich consumes your time and energy and prevents you from achieving your life goals and enjoying life.
To become a serial killer is to leave social life on a second plane as a cover-up and live for the kill.
In other thoughts my favorite serial killer is Tsutomu Miyazaki, but i wouldn't call him an otaku, he had gore films and other things besides hentai, and I don't think his hobby or the rat-man made him do it, he simply chose to step on the other side because society didn't offer much for him, or some other reason, maybe just for fun! :)
Btw i agree with DisgustingP 100%!
