I believe that it is high time that we started a little something... the honoring of excellent villains. Villains who set the standards or broke ground for other villains of today. Villains who deserve a bit of recognition for their... "services" to the world. I will begin by saluting....

The Scorpio Killer, from Dirty Harry. As Dirty Harry, Clint Eastwood became the archetypal action hero. He could not have done that, however, without the help of a psychotic snyper with a taste for blood, played by Andy Robinson. The Killer was a step ahead of Harry Callahan through most of the movie.
Spoiler:
And even when Harry managed to catch up with the Killer and persuade him to give up the whereabouts of his latest victim, the Killer still managed to get off scot free by taking advantage of a technicality in the system.

Everything about this guy, from the "choir boy" face, to the insane, high-pitched voice, the handling of his gun, was wonderfully insane and creepy. His biggest mistake; he was feeling lucky. He should not have felt lucky.

Scorpio Killer (and Andy Robinson) on behalf of Evil, Inc., I salute you. Anyhoo...
