I think I once or twice met a villain who didn’t, who just wanted everyone dead for their own amusement and all the arguments were met with “but, you see, I don’t care.”
...which means they were answering questions rather than trying to kill people^W^W amuse themselves.
Usually, these villains actually find it amusing to see humans fail to grasp their motivations, and/or are stalling in order to get an opening through which to kill people.
I don’t feel like enumerating examples, but I feel like I usually don’t find it convincing (and that it’s usually the heroes stalling and the villains helpfully cooperating).
