This scene in New Moon

I always found this scene in New Moon weird. Edward is mad at Rosalie because he made the decision to commit suicide. It's true that she was wrong to inform Edward of Bella's situation like that, but Edward is the guilty one, he is the one who chooses to go to Volterra to die, no matter what the Volturi's response is. He doesn't inquire, doesn't tell anyone about his choice, not even Carlisle, he puts his family in danger and because of him the Cullens became a target for the Volturi afterwards and at the end of the book we have to blame Rosalie and the whole family agrees with him and pampers him like a prince. But instead of acknowledging his wrongs in front of his family, the story almost absolves him by putting Rosalie in a negative light.
