y'know this actually made me think of a good plot for a short spinoff:

Hardcore christian person finds the death note, spends some time researching who the most evil people are, then follows a year of writing one name every day after which they go through a ritual and prayers and then repeat the next day, and at the end they finish by writing their own name because they know humans can't be trusted with that power and consider themselves to have simply been the hand of god and now it's time to face His judgement.

Basically just literally Silas (the white haired dude) in the Da Vinci Code.
