basically Ford has been cultivating the hosts for 30 years to allow them enough time to become self aware, Arnold originally wanted to close the park because he wanted them to become self aware without the game running, Ford knew he couldn't afford to and Arnold decided to stop him by wiping out the hosts and himself, this didn't work. Ford then with the financial backing of William (MIB) let westworld carry on, William pursuing the maze (which was the hosts becoming self aware) and creating a real world where you could kill but be killed. Ford was using it all to allow the hosts to become self aware by suffering time and time again he felt that was the key to consciousness. At the end Fords new narrative was the hosts to take over by firstly wiping out the humans including himself. I'm interested in the other worlds they obviously have such as Samurai world and how they are affected.
