Does Seanchan have Stedding?

I am on my fifth or six reread and currently finishing Winter’s Heart. I’m always struck by how the Seanchan seem to twist or pervert people and powers into technologies for destruction and domination. They turn Saidar into a weapon, and they turn Ogier into killers (not just when they get angry like Loial does but all the time).

On this reread, it finally occurred to me to wonder whether there are any Stedding in Seanchan? If not, does that explain the transformation of their Ogier gardeners? If the Longing doesn’t kill you, does it turn you vicious?
