Delilah betrayed Samson, Brutus betrayed Caesar, and if those examples aren't enough to shatter your faith in humanity, one time Shirley lied to Laverne and told her she had not, in fact, seen her purse after having lost it when she never asked if she could borrow it in the first place?!?!
But in the eyes of Twilight fan and frequent uploader nuttymadam3575, never has the world witnessed such an unjustifiable tragedy as Kristen Stewart's directly aimed betrayal of her! Oh, and of Robert Pattinson. He's probably really sad, too. Really, when you break it down, it's just a classic love rectangle.
