If you had tons of power, I bet you'd want to do something with it to, if for no other reason than to figure out what you can do, and investing in a planet seems to be the most effective method for them (in addition to lining up with the intents).
I wonder if that Shard or a different one could be Jealousy. God's righteous jealousy is a huge theme in the Bible, particularly the Old Testament, and we know Brandon bases some of this on those attributes. Jealousy separated from the other attributes/mandates of God would be a dangerous thing, though, and a likely partner for Odium (though one just as willing to stab Odium in the back as Odium would be to stab it in the back).
