Perhaps the "magic is about emotion" quote might reference why cora and regina turned evil; it's not the magic that corrupts, but their feelings that corrupt their magic. IE: Both had broken hearts and sought a way to escape from their broken hearts thus they desired power and thus used magic for their purposes.
