Uriel strikes me as the White God’s go to guy, so he has his fingers in lots of pies.
The Knights, Starborn, afterlife enforcement - we have only seen the tip of the iceberg.
Malcolm is most likely a special soul, and shepherded by the Angel of death because his good work attracted the oppositions special attention, most souls do not get this attention. Because of who he was he volunteered to work after he was due for his reward in heaven, he wasn’t conscripted to work his way into heaven like Jack Murphy, whose deal came about because his suicide was prompted by external supernatural forces.
In a similar fashion Murphy and Hendricks were conscripted by Odin, they will eventually go to heaven/Valhalla etc. Murphy as a former Knight was a sure thing for Heaven, Hendricks really benefits from this deal, that’s not where you would expect him to go.
Jack Murphy’s case is more analogous to Hendricks than Malcolm’s.
