Which Game of Thrones characters are atheists or agnostics?

My answer to Which Game of Thrones characters are atheists or agnostics?

Answer by Vijayendra Mohanty:

Game of Thrones is full of characters who have occasionally doubted the gods. Given the time and space that the GoT universe occupies, it might actually suffice to have a rationalist to answer this question.

I think one character, more than any other, fits the bill.

Ser Davos Seaworth

Davos pays tribute to the gods like everyone else of course, but it's lip service. He makes decisions based on common sense and rationality. He is not a true believer like the red woman. He is not a man raging against his fate like Tyrion. He is not someone who even blames the gods for his losses.

He lives in the knowledge that he is a small part of a large world that he cannot control. So he does the best he can with what he has.
