Actually spirits can destroy. Think of Hei Bai. But in this case, La couldn't - as he had given up his spiritual form when he crossed to the mortal realm. What I believe happened was that Aang allowed his powers to be used, in order to temporarily restore La with his Spirit World form, thus empowering La to enact his rage.
