I agree, but I think the goal here is to provide a racial diety for pretty much any type of character. Elves who go over to the dark side have Lolth to worship if they want to stay within (more or less) the Seldarine, the gnomes had Urdlen long ago (and now Garl's dark twin), the dwarves have always had various grimmer figures (and a very nice evil entity now), and halflings need something comparable. I know a LOT of people who play psycopath halflings for some reason (and well before Order of the Stick came on the scene), and now they have a diety that lets them be both very halfling and not particularly cuddly.
More troubling to me is the apparent decision to only detail two halfling dieties at all, and give the others a cursory treatment.
