Do You Think It's a Shrewd Move or a Smart Move?

Since chapter 16, peter has flexed his muscles and bowed up several times. Jesus literally described exactly what was going on at this moment in the garden. And jesus turns to him and he says, get behind me, satan. So i dont think its a shrewd move. I don't think it a smart move. But more importantly, it was am that indicates another repudiation of jesus commands on the part of peter. It's not a good look.
