Hey, your first post. Welcome. Pull up a chair, pull your shoes off. Have some coffee.
I don't believe God has any such choice as to sin. To state that God has a choice or could face such a decision over a moral dilemma implies that he has ability to be tempted.
He has no weakness, no temptation and therefore no choice to make.
To claim that God could make a choice to sin is to say there is some character defect in God's character.
We're the en***ies with defects, due to sin nature.
(And to think that Mormons believe the Fall of mankind was a good and necessary thing. Oh, Bro-ther!)
