Actually, doing whatever you want was what got the devil, and us, into this whole mess. It is simply not how Jesus chose to live. John 5.19 - I assure you, the Son can do nothing by Himself. He does only what He sees the Father doing. Whatever the Father does, the Son also does.
You see, even God has built in accountability. Lucifer rejected this. And we get the chance to choose that way of life again.
