>Why does "necromancy is evil" bring out the biggest contrarians who suddenly want to play good necromancers, while "necromancy is okay" makes people ambivalent?
Because there are these two types of people:
1) That wants to subvert the trope either because they think it makes them smarter than "everyone else" or because they just genuinely just curious and want to try things they haven't tried before.
2) That are impartial and don't really care for the ideals and morality that 1) is interested about, to them necromancy is not any more or less special than other forms of magic.
The main reason it brings this is out because it is rooted in D&D's dreaded alignment system, which in itself is a source countless problems that plague this game since its conception. This is one of those problems, some people like (1)s consider the alignment and morality of the game to be important and try to apply the alignment system and modern day morality to the games they play. Others like (2)s are aware that this is a can of worms that shouldn't be opened because it adds very little to the game and in worse cases it can easily ruin the game for everyone.
