(I hope it's the appropriate forum - if not, feel free to move the topic, mods)
I was wondering: does anyone here read "true crime" books, books on criminal psychology or similar works (some Internet resources, maybe?)? If so, I have a question: do you know any good (meaning, non-sensationalist and reliable) works on serial killers?
I'd be interested in a book (or some other work) that examines why such people commit their crimes. Something that would really examine their minds, what exactly was making them kill etc. I'm especially interested in the whole "compulsion to kill" notion - I've seen mentioned quite often in relation to serial killers, but what does it mean exactly? Have they really been people who had a literal, OCD-like or kleptomania-like compulsion for murder, or is it more of a metaphor?
Also, are there any good books on serial killers who turned themselves in and / or expressed regret? For instance, the Wikipedia article on Jeffrey Dahmer seem to suggest that he was genuinely sorry for what he has been doing?
I'm asking as a part of research for a possible RP...
