Grimm have no souls, humans have souls, therefore human cannot equal grimm, no matter how hard you try to justify it.

it's not that grimm can't use aura, it's that their fundamental existance precludes them from having it to begin with.

Have you watched WoR Grimm? we don't know where they come from, but we know exactly how they work.
