The disturbing) thematic, because in this park humans can perform different actions without consequences, that is, they can move by their lower instincts in a world where they do not have to answer for their actions. For this, they use the hosts (robots) in a scenario similar to the Wild West.
This premise makes many people's fantasy go beyond the accepted boundaries of society. For this reason, there is a large number of deaths on a frequent basis. There, the hosts may die a dozen times in a single episode and be revived, to continue their narrative or start a new story.
Bernard Lowe
This leader in the park's programming division doesn't realize he's also a host until quite late in the first season. This makes him shoot himself in episode 9 "The Well-Tempered Clavier." At the end of the second season he is killed by Dolores, because she needs his control unit, later she brings him out of Westworld, becoming one of the few who survived.
Peter Abernathy
Dolores' father dies a number of times during the plot. He is part of his daughter's narrative, where a group of outlaws attack them on their ranch. There, the Man in Black, a human, gives free rein to his most perverse desires on many occasions.
This host has to be changed, because he begins to show flaws after seeing a photograph that had a human in his possession. The new body follows the same storyline as Peter, until Dolores wakes up and begins to be aware of her reality.
Hector Escaton
He's a most wanted bandit in Westworld, with the terrifying attitude so typical of the wild west. He assumes his role of killer and predator and enjoys it. The leader of the town's gang of thugs has been killed several times, some of them in or near the Mariposa Saloon and at the end of the second season in the battle of the Valley, so he adds up to about four deaths on screen.
Armistice
She's a first-generation host, which means she's one of the oldest in the park. Her character is very tough, ruthless, brutal, and nothing stops her. This member of Hector Escaton's band has died four times on screen, including a murder by the Sheriff, one by Maeve, one by a guest, and one at the end of the second season, where a lot of characters die.
Maeve Millay
This character, like Dolores, questions her reality from the first episodes, after she begins to have memories, especially of her daughter in the first narrative she has in Westworld. Her narrative is changed when she commits suicide after seeing her daughter murdered. From then on, she works in the town's brothel.
Her traumas and memories motivate her to inquire about what happened. She is part of Ford's plan to get the hosts to wake up, but she makes decisions for herself, like staying to find her daughter. She provokes their death at various times to gain access to the Westworld control table to understand what it's all about.
Dolores Abernathy
This host is innocent and sweet, but later changes when she understands her reality and leads the rebellion of the robots. Dolores is the eldest host and for that reason has been reset on a number of occasions. Her seemingly happy existence, in the beginning, is truncated by the death of her love Teddy Flood, her father Peter, and by being the object of obsession for the Man in Black.
She has died on several occasions, such as at the Abernathy Ranch, both at the hands of the Man in Black and by bandits. She has also committed suicide when the park was on test in the beginning and has been killed by the Confederates and by Bernard at the end of the second season, although she is still alive.
Clementine Pennyfeather
Clementine is one of the most used host by humans. First at the brothel of Sweetwater the Mariposa, where she works alongside Maeve, where she dies again and again. And then, she becomes a weapon that causes the hosts to kill each other at the end of season two.
She is often discarded and after this battle she is pushed aside again, so she fulfills her destiny once again in front of the humans. Clementine is one of the oldest hosts. Her role is played by repeating the welcome line to customers and she is scheduled to replace Maeve at the brothel if necessary.
Teddy Flood
In a world of robots designed to fulfill human fantasies, like murder, Teddy is the most killed host. Ford once mentioned that Teddy has died 5747 times. This character returns again and again to Dolores in her love plot.
Among the deaths he experienced on screen that can be ed were those executed by Dolores, the Man in Black, Tenderloin, Angela, and even himself at the end of the second season, when he realizes that his beloved Dolores has manipulated him in the same way as the humans, to help her in the extermination she has planned. Teddy's gentle nature prevents him from continuing and he prefers to end his life.
