Its hard when everything that is yours is not yours anymore and your at the mercy of another. The goal being as such would be to fight for whats yours, but when your being told that your life is the way it is because its supposed to be that way, then its not as simple as it was the first time around. The oppressive forces all had control and superior knowledge that was the prime advantage, but knowledge is power and that is the power that Douglas sought out to achieve, to be oppressed no more.
