So many call their friends backstabbers, but few literally are. That was probably Caesar who coined that term, or at least someone referencing Julius Caesar. "And you too, Brutus?" His wife had a bad dream about him going out, and he should have listened to her. Everyone wanted to kill him, and a good number of people there did.
