Most people placed Enchantment as a kind of Evil.
Due to the number of Mind Control spells it has.
Charm, Suggestion, Dominate, Sleep, Hold, Insanity.. All effects that Enchantment specializes in.
In Necromancy, only a certain spells have the [Evil] Tag.
Mostly ones that animate the dead. Necromancy does have spells that can be used to damage or re-kill undead critters, so a Necromancer would be your go-to person for dealing with restless dead folks.
“She'd become a governess. It was one of the few jobs a known lady could do. And she'd taken to it well. She'd sworn that if she did indeed ever find herself dancing on rooftops with chimney sweeps she'd beat herself to death with her own umbrella.”
