This is tricky...
Let's see, evil with no redeeming qualities or anything resembling pathos or humanity to speak of.
The Emperor from Star Wars
Darth Nhilus from KotoR II
Joker from The Dark Knight(He may be right, but he's a complete monster none the less)
The Comedian from Watchmen(Here despite his occasional hints of humanity)
Micheal Myers from the original Halloween(No reason, no pathos, just pure natural evil)
Light Yagami from Death Note(He may think himself justified, but his delusional insanity comes seemingly out of nowhere)
Judge Turpin from Sweeney Todd(The guy exemplifies perversion and corruption)
A betrayer from Berserk, I won't spoil it... you know the one
Alex from A Clockwork Orange
Mr. Burke from Fallout 3
Any one of them would be an exceptional candidate
