Personally I'm more into Ed Gein. The guy was a poor loner, who was warped by a twisted mother and a series of tragedies. In comparison to Ed Bundy he seems like a really innocent serial killer.
Nah, it's not weird. I know loads of people (including myself) who find reading about serial killers really interesting. Of course, there is a difference between being really interested and knowing about serial killers in a lot of detail, and actually wanting to commit similar acts yourself.
I think you all need to calm down lol.
