Who is the greatest movie villain of all time?

The Kurgan from Highlander deserves a mention…

 If you haven't seen this 1986 movie, it's about a race of immortals compelled to fight one another with swords, oh and they can only be killed byhttps://rb.gy/kbe8vu decapitation. Anyway, it's perhaps best not to question that too much.

 The Kurgan (Victor Kruger) is presented as the strongest of this immortal bunch, he's already 2500 years old when Connor MacLeod (the Highlander) first encounters him in 1536.
