I don't understand Roko's Basilisk. It seems like a mild twist on Pascal's wager, and like Pascal's wager, it has the following problem: I don't see a convincing argument that we actually know what behavior the Basilisk/God actually wants. It's equally plausible to me that the Basilisk/God wants people to be brave and live out their beliefs (which might be "I think this concept makes no sense") and would actually punish the craven pursuit of a different action in the hopes of pleasing the Basilisk/God.
As long as we're suspending enough disbelief to take seriously the prospect of a deity that wants to punish us, it seems like a pretty small jump to believe that we can't predict how that punishment is going to get decided. So, rather conveniently, we can just live without thinking too hard about the Basilisk/God.
