I think it's just easier to write a strawman theist into a game than it is to write a strawman atheist.
A strawman theist is someone who brainwashes people into doing what they want by saying it's what god wants. In this situation, it's the people who have to show them that no, there is no god/cults are bad.
A strawman atheist is someone who does believe in a higher power but doesn't want to be bothered by moral constraints. More often than not, they get what's coming to them by god/society punishing them in some way. Unless we're playing as god, that doesn't write well into a game plot. The boss would get what's coming to him off screen or through social interaction. If the player kills him or ruins his life, he's going against the teachings of most religions. The player would be robbed of the satisfaction of putting an end to his evil, athiest schemes.
