Malgus (Earth-5171)

"The reason of my banishment was very... ridiculous. I would've thought to turn back to the Light Side, then get back to the Dark Side, but I'm too late to do that. I've disgraced my own friends, the Sith, I disgraced myself, one of the mightiest Siths in existence, and I have betrayed the Sith Order. However, rather than being hateful towards them, I was supposed to say thank you. My exile, my losses, my hatred, my rage and wrath, all of those, just made me stronger. Behold, the true master of the Dark Side."
