Did you even pay any attention to the story of the games? Because it doesn't sound like you did.
Neither the King of the Wild Hunt, nor Jaques de Aldersberg are evil.
de Aldersberg (Alvin) is a source and can travel through time and space. There is a prophecy on the Witcher books that the world will freeze and humanity will die. He traveled into the future and saw this the end of humanity with his own eyes, so he decided to save the humanity by creating mutants that can resist the frost and lead the humans to the south, were they can survive. His saw himself as the savior of humanity and because of this he thought his actions were justified.

Lodge of Sorceress:
Evil bitches? Really?You reduce the 10 women of the lodge to that?
The main goal of the lodge of sorceress is to create a state under their rule, which includes the whole north. Creating a united state, which power can match the power of Nilfgaard is in their opinion the only possibility to create a balance of power between the North and Nilfgaard and finally end the repeating wars with Nilfgaard and the conflicts between the Northern states
And there is someone on the level of Tywin Lannister. The guy voiced by Charles Dance:

I know Jacques is Alvin. He's still unleashing mutants that he cannot control and allying with people like Salamandra, causing no end of trouble, and the game makes it clear that his visions are no justification. ''This sword is for monsters'' and all that.
I haven't played TW3 nor dwell in its lore forums so I can't say anything about how the King looks like in that game. As we see them in TW1 and the marketing for TW3, they run around destroying villages and tried to kill Geralt. It's nice to know TW3 will make them something else, but this info wasn't present in TW1.
So basically yes, their motivation is power from what we see in-game. They take over the dragon, attempt to cause chaos to further their own ends, and get outplayed by basically everyone else. I've played the game, I know what their deal is. Hasn't changed my opinion of them.
I concede that Emyr can indeed be considered as such. I just hope they portray him well in TW3.
Still leaves lot of card carrying villain in the series. Loredo, Henselt, the Professor, the Reverend, Azar Javed, the Ambassador. The ratio isn't different from Dragon Age's as I see it, which also has a mix of straight up villains (Branka, Howe, Meredith, Erimond) and more complex ones (Loghain, Arishok, Calpernia, perhaps Flemeth and Fen'Harel).
