Let's Talk Serial Killers, Shall We?

I am so interested in serial killers, being a man who likes to know about why people do what they do, and the hidden motivations both positive and negative are completely unexplainable. It's just I wish I could really know what they are thinking, how they are feeling and what in their head is telling them that what they are doing needs to be done!
Very interesting topic of conversation you have started here !
