Question: Why would Rex, a US soldier who fought to protect his country, turn traitor and decide to become a man who wanted world domination?
Question: In the flashback scene of Rex entering the secret facility, what was he looking at on all of the computer screens and why would he use them later on after he faked his death?
Answer: He was left for dead by his own comrades, badly injured by an airstrike that they called down on his location. He would likely say that his country turned against him, not that he turned on them.
