This is a thought experiment where we consider the ramifications of holding this belief. In a universe where this belief is held, your existence may be thoroughly miserable. Would you accept that? And even if you did personally, on what basis do you have the right to make this decision for everybody else? The rational and moral behavior is for you to decide your own fate and leave others alone.

If we are waving away the natural laws of the universe (which we must for the hypothetical to be possible) than the consequences can be anything anyone in the sevate chooses them to be, because there is no longer any rule between cause and effect.
