That could be, but I also have to say as someone who has done it in VO roles that it is a lot of fun to play a villain because you get away with chewing a lot more scenery and your character is either so broadly-written that you can have fun with the broad choices or so complex that you have make a lot of fun with the details. And I know I personally have never played a role in between. I don't know that the former really requires empathy, but you can still be hated for your roles when you play the former all the time.
I imagine at her level, which I was nowhere near, she got to have fun playing the complex villain whenever she wanted after that Oscar. And if I had her talent, I would too.
I got to do a sort of evil business guy monster character for a game and I got to do a heavy Brooklyn accent, which is my favorite accent to do, so I really enjoyed that.
