I don't know if you ever read the story of Julius Caesar assassination. For along time there were conflict between Caesar and Senate. Finally a group of senators plan to murder him. They made a false petition and called Caesar to read it.
When he started reading the fake petition, suddenly one of the traitors pulled down Caesar tunic and the other stabbed him in a neck. within the moments the entire group of traitors striking him out one by one. It is said that, there were 60 men in his assassination and Caesar was stabbed 23 times. Among those 60 men, there was one who called Brutus. Brutus was like a son to Caesar, he was highly trusted and accepted in Caesar's inner circle.
It says that when Brutus stabbed him in the back, Caesar turned back and looked at him in shock and said "You too, Brutus??"
For some reason, I just remember this story...
