EDIT: I should point out that I also almost completely ignore alignment. I really liked the idea from 4e of most regular guys being completely unaligned, since that's pretty much what I was already doing to begin with.
EDIT EDIT: It also occurs to me that maybe you were just legitimately asking me some further questions about this instead of not "getting it." As I said at the beginning of the quoted portion, these gods aren't really into worshippers in the traditional D&D sense, and Freeporters in this version of Freeport weren't often religious, but they were highly superstitious. Basically, they respected the ability of a really powerful supernatural entity to really screw with their day if it wasn't properly appeased. I didn't give any thought to metaphysical or afterlife considerations; basically the gods were just angry pricks who needed to be propitiated so they didn't destroy you. I kinda looked at the relationship of the Aztecs with their pantheon as an example for how this would work. Or, for that matter, most other real world pantheistic religions. It's not a question of gods trying to attract worshippers by means of their agenda, their promises of an afterlife, or anything like that. It's a question of the gods demanding respect, and threatening to wipe you out if you didn't give it to them.
That said, they were still rehabilitied from a PR standpoint sufficiently that it isn't unthinkable that someone would worship them. Someone who spends a lot of time on the sea might decide to devote more than the customary prayers and pre-journey rituals to Dagon, for instance.
