I'll admit, the necromancy is the most clear and obvious abnormal part of the whole matter. Disturbing the dead is seen as something that You Do Not Do in a large number of cultures, be it for reasons of religion, of respecting natural life cycles, or the fact that it often smells very bad to be dealing with corpses in various states of decomposition. Given how much your world centers around it, the differences only then multiply.
In my experience, belief can make someone do some deeply awful things if they really stick with it. It applies outside of religion to particular leaders or nations too, faith is just the easiest and most obvious example. The religious individuals that murdered my mother or otherwise watched her burn alive believed in their god and that their scripture said that they shouldn't permit a witch to live. Look how much damage that caused.
