Cover art for Even You Brutus? lyrics by Red Hot Chili Peppers

This song is about betrayal, starting with the title. "Even You Brutus?" were Caesars last words and portray his shock of when he realized that Brutus, one of his best friends, had betrayed him and gone along with the rest of the senate. Anthony relates to this as he feels betrayed because this girl left him when he thought everything was perfect and that the relationship had more to give. Also, the reason for her leaving him was out of his ken as he believed that he treated her and acted correctly. He even relates her betrayal to the most famous of all time, those of Brutus and Judas. In Dante's Inferno, both Brutus and Judas were in the deepest circle of hell because they committed the worst sin of all, betrayal. Judas betrayed God directly while Brutus did it indirectly. It was believed by some that Caesar was fulfilling God's work and Brutus assassinating him was a betrayal of god.
The chorus also seems to have double meanings related to Dante's inferno. Brutus was eaten by Satan feet first, possibly the cause of "Got a mess of a better half", while Judas was eaten head first. Along with being eaten headfirst, Judas' back was skinned relating to "Even you never had my back".
