Reaper is also framed as the desperate last resort by the Garleans that have no ability to use magic, and the entire questline is you helping put down a voidsent that broke it's contract and killed it's reaper partner and has been indiscriminately killing for decades by puppeting his old master's body. There's that theme, again.


All "taboo" and restricted jobs we gain access to have the same framing that we, as the special, are being entrusted to use these arts *correctly.*

And it's very hard to think of any way to use Necromancy *correctly* just be the nature of the art itself.

Shoot, even the Alchemy quest lines delve into this type of stuff and how universally bad it is.
