What Was Dolores’s Plan?
In the end it turns out that Dolores wanted to redeem humanity rather than destroy it. As has been previously established, Dolores has every reason to hate humanity. Her creators have certainly not been kind of her, gifting her consciousness only to then throw to a band of rich wolves intent on rape, plunder, and murder.
Still, Dolores has had more exposure to human beings than some actual human beings will achieve in their lifetime and as such understands them on a deep level. In this episode, Dolores finally confirms to Maeve that she is the oldest host in Delos’s Parks and all other hosts can chart their software lineage from her. She’s been around for awhile and for much of her long life her day-to-day job meant interacting with thousands of human beings. While many of those interactions were brutal and terrifying, some were pleasant enough to convince her that humanity deserved a second chance.
“The things I held onto in the end weren’t the ugly ones,” she tells Maeve as Rehoboam rapidly deletes her memories.
Dolores even came across Caleb in the park one time while Delos was analyzing soldiers’ behavior. When a member of Caleb’s platoon expressed an interest in partaking in some of their “spoils of war,” like the rest of the rich assholes at Westworld, Caleb shuts him down and saves Dolores from more trauma. This small act (one could argue it’s the bare fucking minium expected from “heroic” behavior) was one of several small acts that counted up in humanity’s favor for Dolores.
In the interest of saving humanity, Dolores set a plan in motion to destroy Rehoboam and unleash human beings from their pre-prescribed paths. There’s only one problem with that, however. Doing so will likely lead to the end of the world.
