"Ok, so you passed him. You did it for good reason. You didn't want to crush his dreams. You made a choice that turned out bad. But you never made the actual choice to kill him.

He may have said that it was your fault while you were fighting but he was trying to hurt you. He clearly doesn't believe it if he never blamed you. He loves you and you clearly love him. Isn't that enough?"
