It's kind of odd that you don't get any dialogue options to comment when the character rants about how deceitful, worthless, nasty and useless Selune is - when in a world of present and active deities, and true tangible good and evil (celestials and fiends etc.), it's empirically known and established that Selune is an overwhelmingly good deity - greater deity, in fact, known the realms over for being a good deity, a champion of life and knowledge, and proven so.

But we can't say "Hey, um... you're, ah, a bit misinformed there, friend.. you've been a bit lied to, perhaps..." That option is absent, and it's weird.
