I Take Full Responsibility, I Should Have Left It

Moses asks Aaron, what did these people do to you that you have brought such a great sin upon them? We would want to see an acknowledgement of the gravity of what he's done. And instead, Aaron says, "Let not the anger of my Lord burn hot" This is a bad confession; it's not any kind of a statement of repentance. It's a bad sign about Aaron's own spiritual state here.
