Human sacrifices
Alright, we think that this list has gone off the deep end and now we are entering some spooky territory. We have never actually seen anyone worship the devil before, but we have heard that it is quite real and terrifying. That all depends on whether or not you believe in that stuff though.
We are not really sure if the devil is real and that he can have an influence on us here on earth, but human sacrifice is something else. Imagine walking around that old farm knowing that people have been sacrificed for Satan there. Talk about a creepy family connection to have so close to home.
