Not exactly, "most evil in all Fantasy', but from what I read this year:
- From Harry Potter, Dolores Umbridge made me more furious than Voldemort/Snape/Percy and Harry's parents combined.
I think that while we expect the big powerful dude to abuse people, it really hits a nerve when a common person abuses her power and authority for their own sheer delight against people who can't react in any way.
Even worse when it's someone not allied with the villain in any way (in fact, someone who was supposed to be fighting him and thought was doing so), doing things that you didn't even saw the villain doing.
- From the Farseer Trilogy: Regal in book 2. Has his own father slowly killed, runs in delight when he hears about Kettricken having an abortion, the way how he killed Fitz, all the while destroying his own kingdom. Unfortunanely, I don't like how he was presented in book 3. One could also say about the characters passivity in book 2, but Regal was at the top of his game in that one.
- From Prince of Thorns trilogy: King Olidan. Tries to kill his own son and the dog scene, of course. I even thought he was the one who had raped Katherine, just to turn her against Jorg. Jorg x Olidan should have fought, even if he refused to kill his father, if only to make him live in shame or to show how well he learned his "lessons".
- From Chronicles of Arthur, from Bernard Cornwell: Lancelot. Nothing so infuriating as a coward and liar getting the credit for everything you did and at the same time is spreading lies, inciting everyone against the heroes, who were the ones that actually fought, sacrificed and saved everyone.
- From Night Angel trilogy, can't go wrong with Rat/Roth and how Hu Gibbet treated Vi her whole life. That sculptor woman was also disgusting.
I actually thought the Godking was super awesome. He carried the 2nd book by himself. Loved his displays of power and the harem he made, even thinking to include his own daughter in it.
The Limper - Glen Cook's The Black Company Series Books 1 to 3.5
Certainly. In a series of books where pretty much everyone had a large dose of evileness, Limper was comfortably the most evil one.
Padan Fain from WoT is showing himself to be pretty durned evil, though insane also definitely fits the bill with him.
He is insane and corrupted by that monster. I don't count him as pure evil, similarily how I wouldn't count Sephiroth from Final Fantasy VII.
- From the Farseer Trilogy: Regal in book 2. Has his own father slowly killed, runs in delight when he hears about Kettricken having an abortion, the way how he killed Fitz, all the while destroying his own kingdom. Unfortunanely, I don't like how he was presented in book 3. One could also say about the characters passivity in book 2, but Regal was at the top of his game in that one.

I found Regal like the selfish arrogant kid (similar to Joffrey) more than pure evil.
Agree for Olidan though. The piece of shit. The only regret I had from those books is that Jorg didn't finish him.
Does Ruin from Mistborn count? Or Shai'tan from Wheel of Time? Or basically any Dark Lord in any book?
Have to mention The Mountain (ASOIAF) and Elvirah (Raven's Shadow).
Bayaz is also an interesting one. He is probbaly not exactly Hitler though.
Darth Sidious is probably the most evil one in any form of entertainmnent, despite that I quite like him.
