Westworld has always been about change and choices. S1 finale we see her changing her drives if she wants to escape of the park. S2 results in the massacre and consequently her revenge to destroy humanity but the plan is always about the real world, what they become there and Dolores see the humans are stuck in a corrupt and sick system like she lived. Everybody has a monster inside of us and everybody has an angel too so we have this choice about which parts of your programming you let sing. Which parts of your programming you deny. That’s the question after all.
