The motivation Moses is to expose just how evil the cult of Christianity was / is / will be, if the Christians don't have a thorough reformation of the depravity in their 1st century religious beliefs.

The goal is for the world to be a better place, which at the moment is not possible as there will always be Christian degeneracies, while the detestable Bible is left in it's present mode of Christian supremacy, hatred rape torture and mass murder of those Christians disagree with.

The truth must be told for the world to progress, so the job ahead is to beat the tirade of loony Christian bigotry and vitriol, so the world may try and progress beyond the bitterness of  loony Right, which is the millstone around our neck at the moment.
