See. I don't think Uriel's gambit with Harry was equal to Lucifer and Hell's actions in Small Favor, which is why I think Uriel has a long game in plan for Lash in making her into a REAL angel, say the Death Angel we see in Ghost Story that is familiar with Harry.
So, part of Lash + part of Harry=>Bonnie. part of Lash + Uriel's Investment=>Death Angel
Uriel's other balancing act was to allow Harry to tap into Soulfire, which was the other side of the same coin as Hellfire per WOJ.
IF Harry has Hellfire, he can access Soulfire. If he has access to Soulfire, he can access Hellfire.
He can't access both at same time though per WOJ.
We know Angels can use both. I don't know if mortals can. This power is the SAME COIN, however.
Uriel wants to destroy a galaxy: hellfire.
Uriel wants to create something: soulfire.
So, its like destroy vs. create; chaos vs. order.
Now if you are an angel that goes around mainly destroying everything, you aren't heaven's angel. This is all consistent I believe with WOJ.
#259 “Does the same apply to hellfire/soulfire. What would happen if Harry were to take up Lasciel’s coin and then try to use soulfire and hellfire together? Would that result in Harry dying horribly?”
Those are different. They’re really two sides of the same coin–but they can’t really exist together like that. They aren’t explosively reactive, but they aren’t additive, either. Which one came into the person to be used would depend on the person who was using it, and what they were using it for.
Angelic types have access to both. Which one they use is partially what determines what /kind/ of angels they are. (Emphasis added)
