The minds of people eaters (idk how to spell)

I am really interested in how the brain works of many murders. Mostly because most people couldn't even think of or manage to get away with it. The people that have murdered a ton of people really interest me because many don't feel guilt for what they have done. While when I did some studying I came up with a theory maybe people are just yummy and I can't stop eating them.I don't know anymore I was prepared to write a whole essay but got lazy.
