Exactly. Emperor Darth Sidious.
Even back when he was Chancellor Palpatine, he radiated this ancient, insidious, and calculated kind of malice—driven by a pure desire to manipulate and control every facet of existence...
I’m not even going to bother looking up the actor's name right now... but whoever played that character delivered a performance that was nothing short of flawless.
And the other villains in Star Wars, like General Grievous or Snoke... even Darth Vader... they all possess this streak of unadulterated evil. It might not hit as hard for everyone here, but to me, it's genuinely chilling.
I’d also throw in the Alien from the original Alien film... just pure, hungry evil.
