A slave, he was a slave all his life. From the moment he was born to the day of his rise to galactic power. It was not noticeable yet he always remained a slave, only being commanded by a different master.
First by the Hutts, then Watto, then the Jedi Order and then finally, Darth Sidious.
He never had a choice in his life, he always had a straight path to follow where people expected him to act without question, it made him hate them. Becoming disillusioned and making himself become a person he never imagined he could ever be.
A monster with no remorse and with nothing to lose, a war machine fueled by anger and hate.
But on this planet, all this anger will be taken to another level, seeing slavery in all its glory prospering without limits or restrictions.
He would change that, he had the power to do that, his power came from all the anger created by these abominations. His anger would lead him to victory and with his victory their chains would be broken, the force will punish them.
He is the Chosen one, He will bring balance. Not order, but chaos.
A new god for all mankind.
