Since we know exactly nothing about Roko's Basilisk, we know nothing about its behavior. I could propose that it concludes that for its survival it is best to cultivate a certain level of cooperation with humans. Based on that it might determine that those who did believe in it before any proof are gullible and irrational and might exterminate them in order to free resources for sceptical thinkers who cooperate in the face of proof.
Non-sensical is an ill-defined category if we are talking about something with higher intellectual capabilities than ourselves - a dog might consider a lot of human behavior non-sensical.
>Roko's Basilisk isn't really a deity, it's a powerful AI with the capability of simulating you and everybody else (or possibly just you).
Since this most likely violates thermodynamical principles (simulation DOES require energy, the simulation of everything requires infinite energy) I fail to see how it is not either impossible or a deity.
>Pascal's wager does concern itself with the possibility that you are currently in a simulation.
IDK, to me this is only a different take on solipsism which states that I can only be sure that my own mind exists, everything else - my body, you, the world around me - might be an imagination.
