I've tried to combine the two loglines (forgive me if I know not what I do :)

'Faithless' rang better in my ears. Also, by adding the cast and himself, I felt the stakes rise, for it could kill them too.

Thank you.

Thanks Savino.

I was going for a coward needing to overcome his fears, but the theological angle could work too.
