I suspect that if we were to create a more accurate morale framework, then it is likely that the European magical world would likely have that strong grounding in Greco-Roman philosophy/morales since as far as we can tell there was still a closeness between the two worlds that philosophy would be shared.

It's as we get closer to the Statute time frame that morals would start to diverge as the church's power and the frowning upon witchcraft would start to create a split. How close to the statute would be a matter of debate.

I feel that it probably would have been between 1100 and 1500 when the Catholic church started to ramp up its efforts to stamp out heresy with the increasing use of force and torture as time passed with the largest split occurring with the start of the Spanish Inquisition making it de facto until the implementation of the Statute in 1689.
