Well, to be fair, Gallerian was accepting bribes to let serial killers go free and possibly condemning innocent people if they didn't pay up. He wasn't completely innocent there. Aside from this, he was gathering all the sins together for himself, which if not as horrible as Prim in scope might count in Epitomes of Greed due to, well, being all the sins.

That or Prim just wasn't susceptible to the demon.
