"Etu Brute" is a Latin phrase meaning "And you, Brutus?" It is famously attributed to Julius Caesar, a Roman general and statesman, during his assassination in 44 BCE. The phrase symbolizes betrayal, as Brutus was a close friend of Caesar but participated in the conspiracy to kill him. The expression has since become a cultural reference for unexpected treachery, often used in literature and popular media. It highlights the themes of loyalty and betrayal, particularly in political contexts, and serves as a reminder of the complexities of human relationships, especially among those in power.
