Elliot and Mr. Robot are technically the same person, but they are also two separate personalities within Elliot’s mind. Elliot suffers from dissociative identity disorder (DID), which is a mental condition in which a person has two or more distinct личности, each with its own thoughts, feelings, and memories.
In Elliot’s case, he created the Mr. Robot personality as a way to cope with his childhood trauma and to protect himself from pain. Mr. Robot is a confident and charismatic hacker who is the exact opposite of Elliot in many ways.
Throughout the course of the TV show Mr. Robot, Elliot and Mr. Robot work together and against each other to achieve their own goals. Elliot wants to bring down the corrupt E Corp corporation, while Mr. Robot has more personal and selfish motives.
In the end, Elliot and Mr. Robot are able to integrate their personalities and become one whole person. This is a difficult and painful process, but it is the only way for Elliot to truly heal and move on with his life.
So, to answer your question more directly, Elliot and Mr. Robot are the same person in the sense that they are both aspects of Elliot’s personality. However, they are also two separate individuals with their own thoughts, feelings, and motivations.
