Really, I would say, why stop at just "living well"? Yes, it's certainly a very important way to overcome and render null the actions of those who have wronged you, I'm not downplaying that important part.
But there's also something to be said for actual Revenge. That combination of Revenge and Passion has fueled many of the great works of statecraft, art, science, engineering, music, and yes, the RPG Hobby. So many amazing things have only come to exist because of Spite.
In the modern world's obsession with the Baby-Boomer meme of "niceness", we have forgotten just how significant something like revenge can be in terms of genius.
Clearly, Peter Capaldi hasn't. He was refused the chance to be president of the Doctor Who Fan Club in the 1970s, when he was a teenager, and the BBC PR people apparently mocked him. So he decided to avenge them all, and become Doctor Who. And a truly great, grumpy, and spiteful doctor he is!
