I think I'd have fun with it. I put 100% passion into the things I love, so rest assured I'd be doing my villainessing with a certain finesse.

I truly enjoy playing a villain who makes the protagonists think. Question their own path. Perhaps turn to the dark side. Eloquence shrouded in darkness and a touch of charisma.

Ooo, those are fun! I'm not positive I have the skill to play one, though.
I'm more fond of utterly brutal villains. The one who likes to play with their food; methodically separates the heroes from all they love before completely destroying them, physically or mentally.
I know it's not deep, but if played just right, it can be the most terrifying experience.

I wholeheartedly agree. I have a villain who was driven mad by possession. He is a terrifying experience. Unpredictable. Ruthless, yet never at his own command. Always following the will of demon within. Forcing the protagonist to chose between the ones they love of the home town they grew up in. Holding their prayers just within reach only to snatch them away and feed on their essence as they wallow in despair.

Entirely. In fact, my favourite character is just that: a literal demon from the deepest layer in Hell.
It actually got to the point in the RP where our characters were a little too irreparable. Hah, whoops...!
Regardless, it was a pleasure to play him. He was a charismatic character whose motives were as clear as well-polished glass: Wrath. Piss him off, and he'll sink the entire ship just to take down the captain. That includes himself. He'd accept the most horrible death imaginable if only it meant his enemies had the same one as he. He'd do it with open arms and a grin.
