I have NO idea what any of that means...
Oh, um... have you ever heard of Terry Pratchett's Discworld series? Samuel Vimes is the head of the City Watch, and regardless of what ranks he's been awarded with, feels that he is, and always will be, A Watchman, and knows that that identity of being a Watchman keeps him from being just as bad as the scum he hunts. The encounter that I mentioned is a scene in the book Thud! where he's been possessed--somewhat--by a being known as the Summoning Dark, a "quasi-demonic entity of pure vengeance" that had been called by some dwarves in response to their murders.
The Summoning Dark is running around the deserted city of Vimes' mind, and it's being followed. By Something. And just at the end, when Vimes is ready to exact vengeance--not justice--on the dwarves in question, he stops. No one would know if he killed them all. But he stops. And in his mind, the Summoning Dark has just met Vimes' own personal Watchman, the Watching Dark. "He created me. Quis custodiet ipsos custodes? Who watches the watchmen? Me. I watch him. Always." [...] "But I think you misunderstand. I am not here to keep darkness out. I'm here to keep it in." And then he, this personal avatar of Vimes' belief in justice, evicts a semi-demonic avatar of revenge. Without help. Without ritual. Without anything other than pure belief in Justice over Revenge.

Now, to keep this from thread-jacking, I'll say this: Uriel is the Watchman, right? And the Watchman needs to consort with lowest of the low as part of his work, all the while remaining incorruptible, must remain vigilant, and be willing to do violence, not only to others, but to his peace of mind and soul, so that others may live in peace.
Translating that into game terms is going to be a bit of work... any thoughts?
