The Sith took everything from me. Ripped me from my mother's arms. Murdered my brother. Used me as a weapon. Then cast me aside, abandoned me. Once I had power, now I have nothing. 

Too late for what? The republic to fall? It already has but you just can't see it. There is no justice, no law, no order, except for the one that will replace it. 

It was I who languished for years, thinking of nothing but you. Nothing but this moment, and now the perfect tool for my vengeance in front of us. I never planned on killing you, but I will make you share my pain, Kenobi.
