I noticed your edit to Maleficent's page, and I wanted to address something to you:
Although it is indeed rare, there are in fact people in the world who actually do know full well that they are evil and enjoy doing evil. To give a few examples, there's Tamerlame Khan, aka Timur, specifically his quote here right before ordering the sacking of Damascus:
"I am the Scourge of God, appointed to chastise you, since no one knows the remedy for your iniquity except me. You are wicked, but I am more wicked than you. So be silent!"
Another person in real life who actually WAS aware that he was evil and enjoyed it is the Marquis de Sade, and it's clear he knew full well he was evil and enjoyed it from this quote: "Imperious, choleric, irascible, extreme in everything, with a dissolute imagination the like of which has never been seen, atheistic to the point of fanaticism, there you have me in a nutshell, and kill me again or take me as I am, for I shall not change." Which you can read here: http://thinkexist.com/quotation/imperious-choleric-irascible-extreme_in/346903.html
And based on what Jim Smyth indicated regarding the criminals he interrogated, there have been a few of them who enjoyed the evil label as well: http://www.youtube.com/watch?v=Ah51vPzcVEM#t=2m46s Don't get me started on several serial killers such as Son of Sam.
So, yeah, I'd personally suggest you keep that in mind next time you consider adding that tidbit in. Besides, Maleficent openly boasting she's the mistress of all evil makes it very clear she's not like most people who think they're justified and don't view themselves as evil.
That's some pretty deep thinking. I mean, Voldemort thinks he's cleaning up the wizarding world, Yzma sincerely thinks she can make the empire way better than its former ruler, so does Palpatine, Frollo thinks he is doing God a favor, Ultron and Surtur think they are bringing about inevitable evolution, Shan Yu and Ronan the Accuser think their missions are ones of justice, against China and Xandar for what they've done to the Mongolians and the Kree, etc. Thanks for putting in the time to explain that to me so I'm not confused in the future.
