Of course Rupert Murdoch is evil. This shouldn't be surprising. Let's analyze his name.
First, your cartoon evil genius name needs a good suffix. -ock, -ok, and -och are all variant spellings of a classic with long, demonstrable history of Sinistrosity:
Morlock, Gorlock, Doc Oc, Spurlock, and to a lesser extent, Hordak.
Then, you need a stem on which to append that suffix. Evil-sounding nouns are all good candidates. Hate, Death, Hell, Crime, or in a nice self-referential twist, Evil. But to really cap off your evil cartoon genius, you just can't beat an evil-sounding adjective. Maim, kill, rape, belch-- I think we can all agree that those are evil verbs. But across all cultures, times, and places, no evil activity is more universal than murder, which is why I suggest appending the evil suffix "-och" to the evil stem "murd." Murdoch. Now that sounds evil!
How about a first name? Here it gets complicated. Even in the case of cartoon villainy, you don't want your genius to fall victim to overkill. That's why there aren't many badguys named Evilman Killestro or Hatebringer Deathovich. Evil geniuses should have that element of genteel panache to them, like Professor Moriarty, or Dr. Evil, whose first name, "Dr." connotes many long years of study at evil medical school, as he would be quick to point out.
Overkill avoidance is therefore the reason why your evil cartoon genius must have a boring, whitebread, WASPy name. In naming our cartoon evil genius, we must employ Chiaroscuro, the method of the Italian masters, in which bold contrasts between light and dark heighten the impact of the composition. To highlight the patent evil of the surname, the first name should sound elegant and refined, such as James, Winston, Preston, or Huntington. Be careful not to employ the diminutive version of these names, because that will immediately convert your genteel evil genius into a superhero, or worse, a hero's childlike bubbly sidekick. Following the the above examples, no super villain should ever have a first name like Jimmy, Winnie, Presto, or Hunt-Hunt. So forget that. Ignore the diminutive temptation. If you stick with high-falutin' pretentiousness, such as an English adaptation of the German name Hroberahtus which itself is a variant of Robert, you should be set.
Yes. Rupert. Perfect.
And that's why, when it comes to evil cartoon geniuses, Rupert Murdoch takes the cake. Without paying for it. Because that's stealing. And it's what evil geniuses do.
