2) Agent Smith in The Matrix.
A truly scary character, particularly considering the film's genre and the time it was made. Most "oaters" make me cringe at least a little these days, and Shane is no exception, but George Stevens got some performance-of-a-lifetime turns on that film, and when the opportunity arises, I always take the time to watch it.
"Prove it."
Other fave hayburner baddies:
I didn't care for the film much but Bruce Dern delivered an amoral and creepy portrayal of "Asa Watts" in The Cowboys.
Of all the performances in the original True Grit, I probably like Robert Duvall's take on Lucky Ned Pepper the most. A dangerous guy and a hard case, but not frightful.
