Essentially that could save the lives of people but would it ? If it's one function is to stop the creation of Roko's basilisk then at some point in time it could have the same goal as the basilisks itself, but this time instead of it being "Torture people who didn't help create it" but instead "Torture people who didn't help prevent it". So it creates a paradox in a way that to stop the basilisk it has to be the basilisk itself.
