They are evil, yes, but beyond evil; I don't believe that there is even a word for just HOW evil they and their ilk truly are.
Well, after what happened in Vegas, it could be said they are Stephen Paddock level evil. Paddock Heads? Paddocked? Not really fair to the other people with the same last name though who did nothing wrong.
I generally don't like to give someone so evil the notoriety by saying their name but since the similarities are so striking I made this one time exception.
