What's the time frame? If it's modern you gotta put in some pop culture icons that might be linked to some sins, sorta depends on your moral position.
JFK, Oswald, Elvis, Michael Jackson, Marlon Brando, Frank Sinatra, Ghandi, Kurt Cobain, Churchill, John Wilks Boothe, Steve Erwin, Anna Nicole Smith, Tupac/Bigge, Malcom X
The above do not reflect my beliefs but I think might work better than more obscure historical figures, even if their evil is more severe. Dante wrote about a lot of contemporaries.
