Draedon is very detached from morals. Even when performing atrocities for Yharim's Forces, he seems to treat it strictly as business. The horrors he committed have as little emotional weight for him as an office worker attending a meeting. It's only ever been fuel for the furtherment of his true goal: complete knowledge of the arcane. It's only when they're researching that they seem to feel anything beyond malaise and canonically a gamer.
